0102 The installation of <B>CLHEP-2.0.4.2</B> is mandatory for consistency in the
0103 definition of masses and widths of particles. Earlier versions of CLHEP may
0104 link, but they will not give correct results.

0121 <H2>3. Items for migration of the user code</H2>
0122
0123 Listed here is some relevant information on developments included in this
0124 release, some of which may require migrations (mainly for users of advanced
0125 Geant4 features) in order to upgrade from release 9.1 to release 9.2.
0126 Note that for all users a full re-installation of libraries (or a full
0127 recompilation) and a recompilation of user applications is required.

0132 An additional optional Boolean argument has been added to the signature
0133 of <TT>ComputeSafety()</TT> in <TT>G4Navigator</TT>. Any class inheriting
0134 from <TT>G4Navigator</TT> has to adapt to the new signature.

0139 Masses and widths of particles have been updated to be compliant with
0140 PDG-2008. To maintain consistency this requires the upgrade to a new
0141 version of the underlying CLHEP library (CLHEP-2.0.4.2), which includes
0142 up-to-date constants as used by Geant4.

0148 <LI>Geant4-DNA processes:<BR>
0149 new elastic scattering models are available for electrons, replacing the
0150 old ones. The user may use in his/her physics list either the Screened
0151 Rutherford model or the Champion model; the models are alternatives and
0152 must not be used together.<BR>
0153 To use the Screened Rutherford model in the physics list, one should
0154 define the elastic process as follows:
0155 <PRE>
0156 typedef G4DNAProcess<G4CrossSectionElasticScreenedRutherfordHE,
0157 G4FinalStateElasticScreenedRutherford>
0158 ElasticScreenedRutherfordHE;
0159 typedef G4DNAProcess<G4CrossSectionElasticScreenedRutherfordLE,
0160 G4FinalStateElasticBrennerZaider>
0161 ElasticScreenedRutherfordLE;
0162 </PRE>
0163 and register it as follows:
0164 <PRE>
0165 processManager->AddDiscreteProcess(new ElasticScreenedRutherfordLE("ElasticScreenedRutherfordLE"));
0166 processManager->AddDiscreteProcess(new ElasticScreenedRutherfordHE("ElasticScreenedRutherfordHE"));
0167 </PRE>
0168 More details can be found in the advanced example <TT>microdosimetry</TT>.<BR>
0169 To use the Champion model in the physics list, define the process as follows:
0170 <PRE>
0171 typedef G4DNAProcess<G4CrossSectionElasticChampion,
0172 G4FinalStateElasticChampion> ElasticChampion;
0173 </PRE>
0174 and register it as follows:

0220 <UL>
0221 <LI>New <I>locator</I> classes and options are available for identifying the
0222 intersection point of a charged particle in a field. These are Simple, Brent,
0223 and Multi-level and allow the user to investigate tradeoffs between increased
0224 accuracy and CPU speed according to the use case.
0225 Multi-level is used by default to provide for robustness; the Brent method
0226 is introduced as an alternative.</LI>

0229 <B>Detector description persistency</B>
0230 <UL>
0231 <LI>A new module for importing detector descriptions in ASCII text format
0232 is now part of Geant4. Such a description can be used as an alternative
0233 to GDML or other persistency techniques, and is provided with a corresponding set
0234 of UI commands.</LI>
0235 <LI>GDML: the GDML plugin module adds export capabilities,
0236 and thus replaces completely the external GDML module required in older versions
0237 of Geant4. The GDML schema has been upgraded to support missing
0238 solids and parameterisations.
0239 The new GDML-3_0_0 schema is now recommended.</LI>
0240 </UL>

0242 <B>Interfaces & Visualization</B>
0243 <UL>
0244 <LI>The layout of the Qt interface, <TT>G4UIQt</TT>, which was introduced in
0245 release 9.1 as a <I>Beta</I> release, has been improved. It now supports both common
0246 versions of Qt: Qt3 and Qt4, and provides all the functionality of previous
0247 graphical user interfaces (such as Xm, Win32...). Also implemented a help
0248 widget to easily browse the entire Geant4 command system.</LI>
0249 <LI>Major Improvements have been made to the Qt visualization driver. This
0250 driver now includes all of the capabilties of the other OpenGL drivers,
0251 but adds additional controls to rotate, translate, zoom, to export to many
0252 graphics formats (jpeg, eps, ps, pdf) and to easily create visualization
0253 movies.</LI>
0254 <LI>The 2D drawing capability has been extended; added in previous release just
0255 for <TT>G4Text</TT>, it now also include <TT>G4Circle,
0256 G4Polyhedron, G4Polyline, G4Polymarker</TT> and <TT>G4Square</TT>.
0257 It allows placement in the 2D "screen window". Useful for tasks such as
0258 creating legends or logos that stay put on the screen while you otherwise
0259 rotate, translate or zoom the visualization.</LI>
0260 </UL>
0261
0262 <B>Low Energy Electromagnetic physics</B>
0263 <UL>
0264 <LI>The Doppler broadening effect is added in <TT>G4LowEnergyCompton</TT> and
0265 <TT>G4LowEnergyComptonPolarized</TT> (using identical model in both
0266 cases).</LI>
0267 <LI>Ionisation cross sections for particle-induced X-ray Emission (PIXE)

0273 <LI>New Paul model for K-Shells (<TT>G4PaulKCrossSection</TT>).</LI>
0274 </UL></LI>
0275 <LI>Added new stopping power model for ions, using by default ICRU 73 data
0276 tables. New templated classes are <TT>G4IonParametrisedLossModel</TT>
0277 and <TT>G4IonParametrisedLossTable</TT>.</LI>
0278 <LI>Geant4-DNA processes:
0279 <UL>
0280 <LI>New charge transfer process by incident protons: two cross-section and
0281 one final state policy classes: <TT>G4CrossSectionChargeTransferCH</TT>,
0282 <TT>G4CrossSectionChargeTransferExp</TT>,
0283 <TT>G4FinalStateChargeTransferProton</TT>;</LI>
0284 <LI>Two new total cross section classes for electron elastic scattering in
0285 liquid water below and above <TT>200 eV</TT>:
0286 <TT>G4CrossSectionElasticScreenedRutherfordLE</TT> and
0287 <TT>G4CrossSectionElasticScreenedRutherfordHE</TT>;</LI>
0288 <LI>New alternative elastic scattering model for electrons in liquid water
0289 from C.Champion's model: <TT>G4CrossSectionElasticChampion</TT> and
0290 <TT>G4FinalStateElasticChampion</TT>.</LI>

0294 <B>Standard Electromagnetic physics</B>
0295 <UL>
0296 <LI>Cubic Spline interpolation of <tt>dedx</tt> and cross section tables is
0297 enabled by default. Better interpolation was found to increase stability
0298 when varying transport parameters, such as cuts, of energy deposition of
0299 hadrons. The old variant of linear interpolation is available as an option.</LI>
0300 <LI>A new process, <TT>G4eMultipleScattering</TT>, specialized for simulation
0301 of <TT>e+ and e-</TT> multiple scattering has been added.
0302 This process in turn uses a new model, <TT>G4UrbanMscModel2</TT>, which is
0303 based on the <TT>G4UrbanMscModel</TT> of previous releases but has an
0304 improved sampling algorithm and has been retuned to experimental data.
0305 Several reference physics lists such as <TT>G4EmStandardPhysics</TT> now
0306 use this new <TT>G4eMultipleScattering</TT> process.</LI>
0307 <LI>A new class <TT>G4WentzelVIModel</TT> for multiple scattering of muons and
0308 hadrons is available as a prototype for validation.</LI>
0309 <LI>New bremsstrahlung model class, <TT>G4eBremsstrahlungRelModel</TT>, includes
0310 advanced description of LPM effect; it can be applied for electrons and
0311 positrons with <TT>E > 1 GeV</TT> and provides gamma spectra which agree
0312 well with thin-target experimental data.<BR>
0313 The density suppression effect in the old <TT>G4eBremsstrahlungModel</TT>
0314 has been reviewed and improved.</LI>
0315 <LI>The <TT>G4IonFluctuations</TT> model has been updated: at high energy
0316 it uses <TT>G4UniversalFluctuation</TT>, which provides Landau tail of
0317 fluctuations.
0318 At low energies it uses Gaussian distribution based on experimental data.</LI>
0319 <LI>The <TT>G4Cerenkov</TT> process now enforces a step limitation at the
0320 Cerenkov threshold and a new user defined step limitation provides for
0321 smoother X-ray emission.</LI>
0322 <LI>A new <TT>G4EmSaturation</TT> class is introduced for sampling of Birks
0323 saturation.</LI>
0324 <LI>A new <TT>G4ElectronIonPair</TT> helper class based on the ICRU'31 report has
0325 been added; it can be used for sampling electron/ion pairs in sensitive
0326 detectors.</LI>
0327 <LI>A new <TT>G4EmConfigurator</TT> class can be used for configuration of
0328 models in physics lists.</LI>
0329 <LI>Initialization of <TT>SubType</TT> has been added for all processes.</LI>
0330 <LI>The printout describing processes, models and their parameters
0331 initialised for a run have been upgraded.</LI>

0340 {
0341 fHadronElastic = 111,
0342 fHadronInelastic = 121,

0347 };
0348 </PRE></LI>
0349 <LI>Bertini cascade:
0350 <UL>
0351 <LI>Barrier penetration has been added to the Coulomb barrier.</LI>
0352 <LI>A bug in the final state multiplicity sampling has been fixed, thereby
0353 correcting the quasi-elastic peak which was too large.</LI>
0354 <LI>Very low values of two-body internal pion cross sections above
0355 <TT>7 GeV</TT> have been brought up to PDG values.</LI>
0356 </UL></LI>
0357 <LI>Binary cascade: the cascade part remains unchanged, however, changes in
0358 the pre-compound and de-excitation code will affect results for low-energy
0359 secondaries.</LI>
0360 <LI>The INCL/ABLA cascade/evaporation model is now officially released.
0361 It can be used for incident <TT>p, n, d, t, 3He, alpha</TT> and
0362 <TT>pions</TT> from <TT>200 MeV</TT> up to <TT>3 GeV</TT>, on nuclei
0363 ranging from carbon to uranium.</LI>
0364 <LI>The quantum molecular dynamics (QMD) model for nucleus-nucleus collisions
0365 is now in <I>Beta</I> release. It is valid from <TT>50 MeV</TT> to
0366 <TT>5 GeV</TT>.</LI>
0367 <LI>The class <TT>G4GlauberGribovCrossSection</TT> now provides a smooth
0368 transition with the Barashenkov cross sections at <TT>90 GeV</TT>.</LI>
0369 <LI><TT>G4ChargeExchangeProcess</TT> and <TT>G4ChargeExchange</TT> model are
0370 now ready to be used in physics lists; the low energy threshold is set to
0371 <TT>1.0 MeV</TT>. </LI>
0372 <LI>Several improvements have been made to the pre-compound model.
0373 Missing pieces of theory were added and several code fixes
0374 were made to <TT>G4PreCompoundModel</TT> and related classes.</LI>
0375 <LI>De-excitation and evaporation:
0376 <UL>
0377 <LI>Several corrections to the multi-fragmentation model to ensure it
0378 conforms with the original SMM model. These were donated by authors
0379 of the SMM model and collaborators.</LI>
0380 <LI>New inverse cross sections and fixes of evaporation probabilities</LI>
0381 <LI>FermiBreakUp is now switched off by default.</LI>
0382 <LI>The pairing correction in excitation energy have been fixed in
0383 <TT>G4GEMChannel</TT>.</LI>
0384 </UL></LI>
0385 <LI>Nuclear mass tables: in order to use nuclear masses consistently throughout the
0386 the hadronic code, changes have been made for the usage of

0452 <UL>
0453 <LI>the bug fix to multiplicity sampling resulted in cutting the
0454 quasi-elastic peak height in half, more in line with the binary
0455 cascade;</LI>
0456 <LI>the same fix increased the multiplicity and decreased the mean energy
0457 of pion secondaries, thus shortening the length of showers in
0458 calorimeter tests by roughly 2% (depending on the physics list);</LI>
0459 <LI>CMS test beam studies show a significant reduction in non-linearities
0460 in energy response to MIP like particles between <TT>5</TT> and
0461 <TT>10 GeV</TT>;</LI>
0462 <LI>improvements to the Coulomb barrier have significantly reduced the
0463 number of protons below <TT>20 MeV</TT>.</LI>
0464 </UL></LI>
0465 <LI>Improvements in the precompound model have resulted in more realistic
0466 neutron spectra at low energies. For <TT>22 MeV</TT> protons on aluminum,
0467 for example, the neutron spectrum now falls exponentially, as expected from
0468 data. Before the changes, this spectrum was more or less flat.
0469 This results in proportionally more neutrons at lower energies.</LI>
0470
0471 <LI>Performance measurements carried out on realistic setups when using
0472 <TT>QGSP_BERT</TT> for <TT>50 GeV pi-</TT>, show an improvement of about
0473 25% in CPU time. A slight degradation in performance of 1 to 3% is instead
0474 measured for <TT>QGSP_EMV</TT>.</LI>

0485 <P></P>
0486 The following known issues affect the cylindrical scoring mesh feature and
0487 are expected to be fixed in the next release.
0488 <UL>
0489 <LI>Rather frequent warning messages may be issued during tracking by the
0490 <TT>G4Navigator</TT>, concerning zero-length steps. This does not affect
0491 the correctness of the results and has been identified in the cases
0492 where a track enters at exactly the center of the top/bottom circular
0493 face along the local z-axis of the scoring cylinder.</LI>
0494 <LI>Speed of transportation in cylindrical mesh is known to be non-optimal
0495 and will be improved in the next release.</LI>
0496 <LI>A problem for some scorers which use the volume size for cylindrical
0497 mesh is identified due to faulty calculation of the geometrical volume
0498 in such configurations. The following scorers currently should not be
0499 used for cylindrical meshes (unless you hand-correct for the volume
0500 after results are obtained): <TT>G4PSCellFlux, G4PSDoseDeposit,
0501 G4PSPassageCellFlux, G4PSCylinderSurfaceCurrent,
0502 G4PSCylinderSurfaceFlux</TT>.</LI>

0516 <H2>7. Compilation Warnings</H2>

0518 There may be few compilation warnings on some platforms.
0519 We do not believe that any of these lead to incorrect run-time behaviour.

0527 <H2>8. Known Run-Time Warnings</H2>
0528
0529 The following message can be written to standard output at the end of a program:
0530 <PRE>
0531 G4Transportation: Statistics for looping particles
0532 Sum of energy of loopers killed:
0533 Max energy of loopers killed:
0534 </PRE>
0535 It provides the total energy (in <TT>MeV</TT>) of tracks killed due to
0536 excessive number of steps ('looping') during the simulation, and the maximum
0537 energy of such a track. Such behaviour can be due to looping in magnetic fields
0538 or encountering problems at geometrical boundaries.
0539 <P></P>
0540 In case either of these reported energies is significant, we recommend
0541 increasing the verbosity of <TT>G4Transportation</TT> to obtain information for
0542 each track killed. A user can change the threshold energy above which particles
0543 are not killed using the method <TT>SetThresholdImportantEnergy</TT> of
0544 <TT>G4Transportation</TT>. The default value is <TT>250 MeV</TT>.
