0112 <H2>3. Items for migration of the user code</H2>
0113
0114 Listed here is some relevant information on developments included in this
0115 release, some of which may require migrations (mainly for users of advanced
0116 Geant4 features) in order to upgrade from release 9.4 to release 9.5.
0117 Note that for all users a full re-installation of libraries (or a full
0118 recompilation) and a recompilation of user applications is required.

0122 <B>Configuration</B>
0123 <P> </P>
0124 <UL>
0125 <LI>The CMake system for installation replaces the old Configure script.
0126 CMAKE has been extended to cover all features.
0127 Complete information on how to use the new CMake system can be found
0128 in the User Installation Guide (Note: the old Configure script has been
0129 removed, as planned).</LI>
0130 <LI>Geant4 now comes with an embedded CLHEP module (based for this release on
0131 version 2.1.1.0 of CLHEP), which includes the subset of CLHEP library
0132 classes required by Geant4. On installation there is a choice between using
0133 this embedded module or installing CLHEP as an external library.
0134 Through the GNUMake system, the use/installation of the external CLHEP
0135 is triggered if the environment variable <TT>CLHEP_BASE_DIR</TT> is set;
0136 otherwise the embedded CLHEP module is used.
0137 With the CMake system, the embedded CLHEP is selected by default.</LI>
0138 <LI>An additional package, <TT>expat</TT>, required by the the new hadronic
0139 <TT>lend</TT> module is also included in the <TT>externals</TT> directory and is
0140 built automatically on Windows. On Linux or Mac, the <TT>expat</TT>
0141 library available in the system is used instead by default.</LI>

0156 <LI>All classes describing interactions of electrons, positrons and photons
0157 (Livermore and Penelope based) have been upgraded to the common software
0158 design adopted by both Standard and Low-Energy electromagnetic domains.
0159 Users are invited to use these upgraded classes following the migration
0160 procedure described in the following page:
0161 <A HREF="https://twiki.cern.ch/twiki/bin/view/Geant4/LoweMigration">https://twiki.cern.ch/twiki/bin/view/Geant4/LoweMigration</A>.
0162 The old obsolete classes have been removed from the Geant4 kernel.

0181 <LI>Number of reference physics lists is reduced. Nearly all EM 'variant' physics
0182 lists are no longer available as a class
0183 in the library (e.g., FTFP_BERT corresponds to a class in the library,
0184 FTFP_BERT_EMV does not exist as a class). However, EM options are all easily available from
0185 updated <TT>G4PhysListFactory</TT>, allowing to use any EM option on top of a
0186 base hadronic physics configuration (e.g., it is possible to request "FTFP_BERT_EMV" by name).</LI>
0187 <LI>The implementation of physics-list constructors (builders) has been revised.
0188 Ordering numbers for processes are no longer used. Old method is still allowed but
0189 it is recommended for a custom user's
0190 physics list to be revised to be compatible with the new mechanism.</LI>

0200 For code that is portable between previous releases and this release,
0201 it is necessary now to use the signature:
0202 <BR>
0203 <TT>void G4Exception(const char* issure, const char* errorCode, G4ExceptionSeverity severity, const char* comments)</TT>
0204 <BR>
0205 Note: the <TT>enum G4ExceptionSeverity</TT> has been defined since Geant4
0206 release 5.0 and its values are:

0229 <H2>4. New Developments and Capabilities </H2>
0230
0231 <B>Geometry</B>
0232 <UL>
0233 <LI>It is now possible to define volumes with material in
0234 parallel geometry layers.
0235 The volumes created can complement or overlap the standard 'main' geometry for tracking.
0236 This new capability is called a "layered mass geometry".
0237 Zero, one or more additional layers for the mass geometry can be used.
0238 This is an enhancement of the existing functionality for parallel
0239 specialised geometries, which has been used for scoring, fast simulation,
0240 shower parameterisation and event biasing.
0241 The registered parallel geometries are scanned now for material.
0242 A side effect of this new capability is that all geometries and all regions
0243 in the each world defined are now scanned for their material.</LI>
0244 </UL>
0245
0246 <B>Materials</B>
0247 <UL>
0248 <LI>Applications with many materials can reduce their memory footprint
0249 by using the new <TT>Base Material</TT> capability.
0250 With it, materials with the same composition but different density
0251 will share entries in the tables of all electromagnetic processes.
0252 Tables with cross-sections, stopping
0253 powers and ranges are precomputed only for base materials.
0254 Any number of materials with different names and densities can be built from
0255 one base material.
0256 So, for example,it is now possible to define large number of "water" materials
0257 with slightly different densities. Only the base "G4_WATER" physics tables
0258 will be built at initialisation; these will be scaled at run time for all
0259 derived materials .</LI>
0260 </UL>
0261
0262 <B>Standard Electromagnetic physics</B>
0263 <UL>
0264 <LI>A new tune of the Urban multiple-scattering model for electrons is
0265 provided. Is is named <TT>G4UrbanMscModel95</TT>. This features
0266 higher accuracy of electron scattering and stability of energy
0267 deposition when the step size is varied. The model is currently set as
0268 the default for electrons and positrons.</LI>
0269 <LI>A new model for Bremsstrahlung, <TT>G4SeltzerBergerModel</TT>, is now
0270 used by default at energies below <TT>1 GeV</TT>. The model is based on
0271 tabulated cross-sections published by S.M. Seltzer and M.J. Berger.
0272 It provides agreement with the low energy Livermore and Penelope models
0273 below <TT>10 MeV</TT> and the standard relativistic model at <TT>1 GeV</TT>,
0274 improving the most over the previous 'standard' Bremsstrahlung model
0275 in the energy range from <TT>1 keV</TT> to <TT>1 GeV</TT>.</LI>
0276 <LI>New biasing options are provided which can be used both with standard
0277 and low-energy electromagnetic physics. They include cross-section biasing,
0278 forced interaction, and secondary particle biasing. The secondary particle
0279 biasing consists of Bremsstrahlung splitting and Russian Roulette. All
0280 these options can be activated per process, particle, energy and
0281 geometrical region via UI commands or C++ code. </LI>
0282 </UL>
0283
0284 <B>Hadronic physics</B>
0285 <UL>
0286 <LI>Interactions of antibaryons (including antihyperons) and light antinuclei with
0287 matter have been implemented in the Fritiof (FTF) model. This model is valid
0288 for incident antibaryon energies from <TT>0 to 1 TeV</TT>, and for incident
0289 antinucleus momenta from <TT>150 MeV/c/nucleon</TT> up to <TT>2 GeV/c/nucleon</TT>.
0290 Corresponding antibaryon and antinuclear cross section classes have also been
0291 added. New processes were added to handle inelastic reactions of antideuterons,
0292 antitritons, anti3He and antialphas.</LI>
0293 <LI>Cascade models
0294 <UL>
0295 <LI> Bertini
0296 <UL>
0297 <LI>The Bertini cascade is interfaced to the pre-compound and de-excitation
0298 module, enabling improved generation of low energy secondaries. This
0299 option is fully benchmarked, and is targetted for applications sensitive
0300 to the spectra of low energy nuclear products.
0301 <LI>An interface for re-scattering the fragments of the high energy
0302 string models has been created. This is an early stage development.
0303 <LI>Bug fixes in the three-body final state reactions provided slightly
0304 better angular distributions of final state hadrons.</LI>
0305 <LI>Memory churn (allocation and de-allocation of memory) was significantly
0306 reduced throughout the model.</LI>
0307 <LI>A new nucleon-coalescence model is available, for improved production
0308 of energetic deuterons and light ions. It is not the default
0309 in existing configurations, due to the extra CPU cost.</LI>
0310 <LI>Gamma-nucleon channels were added for future use, but are not activated.</LI>
0311 </UL></LI>
0312 <LI> Binary
0313 <UL>
0314 <LI>The excitation energy used for re-scattering was improved.</LI>
0315 <LI>The large energy non-conservation observed for hydrogen targets was fixed.</LI>
0316 </UL></LI>
0317 <LI> INCL/ABLA
0318 <UL>
0319 <LI>The first version of INCL++, based on the INCL4.6 model, was released.
0320 It supports proton, neutron and pion projectiles up to <TT>3 GeV</TT>
0321 and uses the native <TT>G4ExcitationHandler</TT> for nuclear
0322 de-excitation after the cascade.</LI>
0323 <LI>The INCL light ion model now supports incident ions up to 18-Oxygen.</LI>
0324 </UL></LI>
0325 </UL></LI>
0326
0327 <LI>Nuclear de-excitation models have been improved to allow <TT>G4PhotoEvaporation</TT>
0328 to be used for nuclei with <TT>Z > 100</TT>. Users may now include their own photo-evaporation
0329 data files. Several improvements were also made to the Fermi-Breakup model to
0330 improve behavior for light (<TT>A < 17</TT>) target nuclei.</LI>
0331
0332 <LI>Several elastic scattering cross-sections, models and processes were extended to
0333 handle antimatter projectiles. These include
0334 <TT>G4WHadronElasticProcess</TT>, <TT>G4AntiNuclElastic</TT>
0335 and <TT>G4CHIPSElasticXS</TT>.</LI>
0336
0337 <LI>A new module which handles quasi-elastic scattering has been created. It is
0338 extracted and now separate from the CHIPS code where it originated.
0339 It is used by all physics lists.</LI>
0340
0341 <LI>Low energy neutrons interactions based on data-libraries:
0342 <UL>
0343 <LI>The Geant4 Neutron Data Library (G4NDL) is now based on the ENDF VII database
0344 exclusively.
0345 Its new version, G4NDL 4.0, is required for use with the High Precision (HP)
0346 models with this release.</LI>
0347 <LI>New translations of alternative neutrons database (ENDF, JENDL, JEFF,
0348 MENDL, CENDL), are being made available separately from IAEA.
0349 These can be used with the current HP neutron models, for studies of systematics.</LI>
0350 <LI>Thermal scattering is enabled in the HP neutron models and the appropriate
0351 data files have been added to ENDF/B-VII, with the exception of para (ortho)
0352 H and D, liquid (solid) methane and benzene.</LI>
0353 <LI>New low energy neutron models (LEND) which use the Livermore neutron database
0354 have been released. They use the GIDI interface to the database.
0355 All information on this database will be maintained and updated by Lawrence
0356 Livermore National Lab.</LI>
0357 </UL>
0358 </LI>
0359
0360 <LI>Radioactive decay has been extended to handle forbidden beta decays and
0361 spontaneous fission. The corresponding data set has been updated to
0362 reflect this.
0363 The radioactive decay code was also corrected to allow atomic relaxation of de-excited
0364 nuclei produced during alpha and beta decay. Bug fixes in the internal conversion code
0365 now provide better agreement with deexcitation gamma spectra. Also, new code and
0366 messenger commands now allow directional biasing of decay daughters, including e-, e+,
0367 gamma, n and alpha.</LI>
0368
0369 <LI>Improved muon-nuclear reactions are implemented in <TT>G4VDMuonNuclearModel</TT>.
0370 Here, the LEP models that used to handle the meson interactions are replaced by
0371 the Bertini Cascade. A new cross-section class, <TT>G4KokoulinMuonNuclearXS</TT>,
0372 was developed which splits out the cross-section code which was formerly
0373 hard-coded into the old muon-nuclear process.</LI>
0374
0375 <LI>Energy and momentum checking at the process and model level can now be enabled
0376 by environment variable. </LI>

0468 <H2>8. Known Run-Time Warnings</H2>

0470 The following message may be written to standard output at the end of a program:
0471 <PRE>
0472 G4Transportation: Statistics for looping particles
0473 Sum of energy of loopers killed:
0474 Max energy of loopers killed:
0475 </PRE>
0476 It provides the total energy (in <TT>MeV</TT>) of tracks killed due to
0477 excessive number of steps ('looping') during the simulation, and the maximum
0478 energy of such a track. Such behaviour can be due to low-momentum particles
0479 which loop in magnetic fields (a physical effect, which can consume a lot of
0480 CPU time for little )
0481 or being abandoned due to being stuck at geometrical boundaries.
0482 <P></P>
0483 In case either of these reported energies is significant, we recommend
0484 increasing the verbosity of <TT>G4Transportation</TT> to obtain information for
0485 each track killed. A user can change the threshold energy above which particles
0486 are killed more reluctantly (only after significant additional effort) using
0487 the method <TT>SetThresholdImportantEnergy()</TT> of <TT>G4Transportation</TT>.
0488 The default value is <TT>100 MeV</TT>.

1321 <LI><TT>G4ReactionProduct</TT>: use <TT>G4Allocator</TT> for dynamic
1322 allocation to reduce memory churn.</LI>
1323 <LI><TT>G4HadFinalState</TT>: store vector of values instead of pointers
1324 to reduce memory churn. Improved constness of argument passing and
1325 functions, and reduced creation of temporary objects. Drop unneeded
1326 staleness flag. Removed <TT>AddSecondary()</TT> interface. Added
1327 interfaces to merge two final states together.</LI>
1328 <LI><U>Models</U>:

1339 </UL></LI>
1340 <LI><B>Binary Cascade</B>
1341 <UL>
1342 <LI>Set E/p checking limits for energy non-conservation checks.
1343 Fixed large energy non-conservation for Hydrogen target (vector for the
1344 final state was not cleared before use). Also moved check for Hydrogen
1345 to <TT>ApplyYourSelf()</TT>.</LI>
1346 <LI><TT>G4GeneratorPrecompoundInterface</TT>: added code to calculate
1347 excitation energy as difference of initial-final state, to allow for
1348 energy conservation for string models. Reduced problem of energy
1349 non-conservation. Fix to add fragment nucleus to reaction products
1350 when no de-excitation. Replaced loop to decay input secondaries with
1351 new <TT>G4DecayKineticTracks</TT> utility. Fixed memory leak in to

1360 <LI><B>Bertini Cascade</B>
1361 <UL>
1362 <LI>Developed infrastructure to support using Bertini as a "rescattering"
1363 model for the output of the FTF simulation.</LI>
1364 <LI>Make cross-section tables self-registering at job initialization.</LI>
1365 <LI><TT>G4NucleiModel</TT>: added optional
1366 argument to <TT>reset()</TT> with list of collision points, for
1367 copying cascade state when rescattering. Optimised computation of
1368 "rho". Reverted length scales to "2.82" factor. Compared local
1369 kaon/hyperon cross-section tables with sum-of-exclusive tables
1370 from <TT>G4Cascade*Channel</TT> classes.
1371 Fixed bug in <TT>G4InuclNuclei</TT> constructor (mom,A,Z,Eexc,model)
1372 to properly set excitation energy; caused energy non-conservation in
1373 de-excitation code. Changed kaon potential to be positive, not
1374 negative, so slow kaons will occasionally be captured.
1375 Removed obsolete local cross-section arrays;
1376 use standard tables, which are numerically equivalent.</LI>
1377 <LI><TT>G4CascadeInterface</TT>: added support for capturing random-engine
1378 state for debug at each <TT>ApplyYourself()</TT> or <TT>Propagate()</TT>
1379 invocation. Simplified <TT>NoInteraction()</TT> to
1380 have no particles returned, but use <TT>SetEnergyChange()</TT> to
1381 communicate to tracking that real track should be stopped and deposit
1382 all its energy. Only projectile is copied to final state, not target
1383 nucleus. If accept/reject loop fails (maximum retries), return initial
1384 state untouched rather than last generated cascade. This avoids
1385 exposing an elastic scattering event under any circumstances.
1386 Use new <TT>G4DecayKineticTracks</TT> in <TT>Propagate()</TT> to
1387 handle short-lived inputs. Set up for E/p checking by
1388 <TT>G4HadronicProcess</TT> in constructor; set internal E/p limits
1389 (currently 5% and <TT>10 MeV</TT>).</LI>
1390 <LI>Simplified cascade test-and-repeat loops; do four-momentum balancing
1391 with nuclear fragment, now used exclusively as <TT>G4Fragment</TT>,
1392 at end of cascade, not after de-excitation.</LI>
1393 <LI><TT>G4CascadeCheckBalance</TT>: added non-limit ctor and explicit
1394 limit setting.</LI>

1396 filled by <TT>copyWoundedNucleus()</TT> for initialization of
1397 <TT>G4NucleiModel</TT>. Reduced number of retries from 1000 to 100.
1398 For pre-cascade rescattering, put
1399 resonances, or any particle which cannot be propagated by Bertini,
1400 directly onto output, without decaying.</LI>
1401 <LI><TT>G4CollisionOutput</TT>: added non-const accessors for lists.</LI>
1402 <LI><TT>G4LorentzConvertor</TT>: added diagnostic messages in <TT>rotate()</TT>.
1403 Drop most "intermediate" kinematic parameters used in rotate,
1404 in favor of somewhat more direct vector operations.</LI>
1405 <LI><TT>G4CascadeChannelTables</TT>: use <TT>FindTable()</TT> to determine
1406 if table has been created already or not. Added new gamma-nucleon
1407 interaction states.</LI>
1408 <LI><TT>G4CascadeGamNChannel, G4CascadeGamPChannel</TT>: new final state
1409 tables for gamma-nucleon interactions, with final states up to 9-body,
1410 using the same energy binning as pion-nucleon.</LI>
1411 <LI><TT>G4Cascade*Channel</TT>: added new constructor argument for all
1412 cross-section tables. Removed all namespace self-instantiations
1413 to fix incosistencies in initialization across platforms.</LI>
1414 <LI><TT>G4Inucl*Particle</TT>: modified all constructors to take the model
1415 code as an optional argument, so that subclasses don't have to set it
1416 manually.</LI>
1417 <LI>Fix in <TT>G4ElementaryParticleCollider</TT> to hide no longer used
1418 "mult" argument to <TT>getMomModule2toMany()</TT>; removed special
1419 "mult==3" case.</LI>
1420 <LI>Fix in <TT>G4CascadeT1NNChannel</TT> to final 9-body final-state list
1421 for both nn and pp: existing entries violate charge.</LI>
1422 <LI>Added protections in <TT>G4LorentzConvertor</TT> for <TT>rotate()</TT>
1423 applied to at-rest system (i.e., <TT>z-axis ~ (0,0,0)</TT>), and
1424 simplified calculations.</LI>
1425 <LI>Updated to reduce memory churn in <TT>G4IntraNucleiCascader,
1426 G4FissionStore, G4Fissioner, G4CascadeInterface,
1427 G4InuclElementaryParticle, G4BigBanger, G4ElementaryParticleCollider</TT>.</LI>
1428 <LI><TT>G4EquilibriumEvaporator</TT>: improved building of final-state
1429 particles to reduce creation of temporaries.</LI>
1430 <LI><TT>G4CollisionOutput</TT>: use <TT>resize()</TT> and set/fill to
1431 eliminate temporary copies. Added diagnostics and fixed bug with
1432 momentum units.</LI>
1433 <LI><TT>G4CascadParticle</TT>: added functions to explicitly set all data
1434 members, including initial path and generation, to support changes
1435 below. Re-order member functions in set/get pairs.
1436 In <TT>getPathToTheNextZone()</TT>, check
1437 for zero momentum (<TT>pp < 1e-9</TT>) and return zero path-length;
1438 this will support capture at rest.</LI>
1439 <LI><TT>G4CascadeCoalescence</TT>: NEW factory class to implement
