0115 <H2>3. Items for migration of the user code</H2>
0116
0117 Listed here is some relevant information on developments included in this
0118 release, some of which may require migrations (mainly for advanced uses of
0119 features in Geant4) in order to upgrade from release 9.0 to release 9.1.
0120 Note that a full re-installation of libraries (or a full recompilation) and
0121 a recompilation of user applications is required.
0122
0123 <P> </P>
0124 <B>Geometry</B>
0125 <P> </P>
0126 The revision of <TT>G4TessellatedSolid</TT> required a name change for some
0127 public methods. User code making explicit use of these methods should migrate
0128 accordingly.
0129
0130 <P> </P>
0131 <B>Low Energy Electromagnetic physics</B>
0132 <P> </P>
0133 The prototype interfaces of beta-version <TT>G4DNA*</TT> processes have been
0134 replaced by a unique process. Prototype user code is required to migrate; in
0135 principle the migration is limited to replacing <TT>typedef</TT> statements.
0136
0137 <P> </P>
0138 <B>Standard Electromagnetic physics</B>
0139 <P> </P>
0140 The <TT>G4Cerenkov</TT> process was changed from being an <TT>AlongStep</TT>
0141 process to a <TT>PostStep</TT> process. Custom user physics-lists that
0142 include <TT>G4Cerenkov</TT> must be changed accordingly:
0143 <PRE>
0144 pmanager->AddContinuousProcess(theCerenkovProcess);
0145 </PRE>
0146 to:
0147 <PRE>
0148 pmanager->AddProcess(theCerenkovProcess);
0149 pmanager->SetProcessOrdering(theCerenkovProcess,idxPostStep);
0150 </PRE>
0151
0152 <P> </P>
0153 <B>Hadronic physics</B>
0154 <P> </P>
0155 Gamma level file warnings in <TT>G4NuclearLevelManager</TT> have been
0156 suppressed, so if an isotope has no data, no warning will be issued.
0157 To turn them on again, set the pre-compiler flag <TT>GAMMAFILEWARNING</TT>
0158 as follows:
0159 <PRE>
0160 CPPFLAGS += -DGAMMAFILEWARNING
0161 </PRE>
0162 and re-build the library in
0163 <TT>processes/hadronic/models/de_excitation/photon_evaporation</TT> of Geant4.
0164
0165 <P> </P>
0166 <B>Fast Parameterised Simulation</B>
0167 <P> </P>
0168 The process <TT>G4FastSimulationManagerProcess</TT> (<TT>G4FSMP</TT>) can be
0169 used for trigger fast simulation models. These can be attached either to a region of the primary 'mass'
0170 geometry or to a region of a parallel (ghost) geometry.<BR>
0171 In the first case, the user has to attach an instance of the <TT>G4FSMP</TT>
0172 process as a <TT>PostStep</TT> process to particles having a fast simulation
0173 model in the mass geometry; this remains unchanged.<BR>
0174 A change is required in the second case, of a ghost geometry: the <TT>G4FSMP</TT> process now must be attached as an <TT>AlongStep+PostStep</TT>
0175 process to particles having fast simulation models bound to regions of the
0176 ghost geometry.<BR>
0177 The <TT>AlongGetPhysicalInteractionLength()</TT> method of the <TT>G4FSMP</TT>
0178 process must be placed second-to-last in this case (i.e. after the Multiple
0179 Scattering, but before the Transportation processes). An example is given in
0180 the physics-list defined in <TT>examples/novice/N05</TT>.

0183 <B>Data Sets</B>
0184 <P> </P>
0185 This release introduces a new data set and two new versions.
0186 Please see the last section for the corresponding details.
0187 <UL>
0188 <LI>New data for neutron cross-sections, G4NDL.3.12.</LI>
0189 <LI>New low-energy data set, G4EMLOW.5.1.</LI>
0190 <LI>New data set for nuclear shell effects, G4ABLA3.0 used by the new ABLA .</LI>

0199 <H2>4. New Developments and Capabilities </H2>
0200
0201 <B>Geometry</B>
0202 <UL>
0203 <LI>Introduced new navigation for phantoms and similar regular
0204 structures. The new algorithm provides fast navigation
0205 and no memory overhead for voxels phantoms and similar geometries.
0206 An option is available to skip volume boundaries, when the volumes on either side hold the same material. The example in <TT>extended/medical/DICOM</TT> has been
0207 revised to demonstrate the usage of the new parameterisation required and the corresponding navigation. In addition it
0208 enables comparison against existing algorithms, including the nested parameterisation (which had reduced memory overhead) and the older 3D optimisation.</LI>
0209 </UL>
0210
0211 <B>GDML detector description persistency</B>
0212 <UL>
0213 <LI>A plugin-module for GDML can be installed optionally in Geant4. This replaces the dependency on the external GDML (GDML-2.X series) library. The new
0214 module includes all the features supported in the old GDML library for
0215 importing GDML descriptions, except for handling of parameterised volumes
0216 and material optical properties. (These will be added in a future version
0217 of the new plugin.) It remains possible to use the old external
0218 GDML library, if needed.</LI>
0219 </UL>
0220
0221 <B>Low Energy Electromagnetic physics</B>
0222 <UL>
0223 <LI>Fully functional capabilities of physics processes in liquid water for
0224 microdosimetry simulation are provided in this release; details can be
0225 found in <I>S. Chauvie et al., "Geant4 physics processes for
0226 microdosimetry simulation: design foundation and implementation
0227 of the first set of models", IEEE Trans. Nucl. Sci., vol. 54,
0228 no. 6, Dec. 2007</I>.</LI>
0229 </UL>
0230
0231 <B>Standard Electromagnetic physics</B>
0232 <UL>
0233 <LI>Non-ionizing energy loss is filled by ion ionisation processes and is
0234 available to user actions.</LI>
0235 <LI>The new process <TT>G4ionGasIonisation</TT> is available. It is recommended
0236 to be used for simulation of ion transport in low-density media.</LI>
0237 <LI>The process <TT>G4CoulombScattering</TT> was verified and is proposed to
0238 be used instead of the multiple scattering process for simulation of
0239 scattering in low-density media.</LI>
0240 <LI>The <TT>G4ScreenNuclearRecoil</TT> process developed by the Vanderbilt
0241 University group is available with the extended example <TT>TestEm7</TT>.
0242 This process is an alternative to the multiple scattering process for
0243 ions.</LI>
0244 <LI>The simulation of energy loss of the classical magnetic monopole is
0245 provided. The example of Physics List with the monopole is available with
0246 the new extended example <TT>exotic_physics/monopole</TT>.</LI>
0247 </UL>
0248
0249 <B>Hadronic physics</B>
0250 <UL>
0251 <LI>Extended applicability of the Binary cascade. <TT>G4BinaryCascade::Propagate()</TT> method is first released. This allows
0252 the use of the Binary cascade to transport the remnants of a high energy collision, as it has become model in the high energy
0253 framework (<TT>G4TheoFSGenerator::SetTransport()</TT>). This feature is
0254 aimed for expert use currently, as validation is starting.<br>
0255 The binary cascade can now be used for pions, benefiting from a bug fix for
0256 incident pions; validation is in progress.</LI>
0257 <LI>The first, alpha release of the new INCL (Liege) cascade module is included. This will be an alternative to the
0258 Binary and Bertini cascades, are already offered in Geant4, and valid up
0259 to <TT>3 GeV</TT>. It has been converted from the Fortran implementation and its validation is ongoing.</LI>
0260 <LI>First, alpha release of new QMD (quantum molecular dynamics) nucleus-nucleus
0261 interaction code. Its validation is ongoing.</LI>
0262 <LI>High precision neutrons: G4NDL 3.12 data set is now released. This uses
0263 JENDL entries for Cd isotopes, and adds four new elements with their
0264 corresponding isotopes: <TT>Hg</TT>, <TT>Ra</TT>, <TT>Br</TT>, and
0265 <TT>La</TT>.</LI>

0269 <B>Physics Lists</B>
0270 <P> </P>
0271 <P>
0272 Several new physics lists are offered, providing new configurations or new
0273 modeling options. Feedback via the Hypernews Forum on physics lists is welcome.
0274 The new physics lists are:
0275 <UL>
0276 <LI><B>FTFP_BERT</B> and <B>QGSC_BERT</B>: both of these reduce the use of
0277 parameterized modeling. For proton, neutron, pion and kaon induced
0278 inelastic hadronic interactions the parameterized model is not used.</LI>
0279 <LI><B>QGSP_DIF</B> and <B>QGSP_BERT_DIF</B>: for diffractive scattering of
0280 proton and neutron at high energies a diffractive scattering model
0281 provided by CHIPS is used.</LI>
0282 <LI><B>QGS_BIC</B> and <B>FTF_BIC</B>: offering new developments of
0283 Binary cascade. For more details, see the detailed notes.</LI>
0284 </UL>
0285
0286 <B>Command-based scoring</B>
0287 <UL>
0288 <LI>The user can
0289 use this new ability to score on an arbitrary three-dimensional scoring mesh, using only new user commands. No user code needs be
0290 written to apply the scoring. It utilises a parallel world making the mesh geometry
0291 can be independent of the mass geometry. An arbitrary number of physics
0292 quantities to be scored and filters affecting these scorers can be assigned
0293 to the mesh. After scoring has been applied (i.e. after the run), the user
0294 can visualize the score map and also dump scores into a file. Relevant
0295 UI commands are listed in the Application Developers Guide, and the new
0296 <TT>extended/runAndEvent/RE03</TT> example demonstrates their usage.</LI>
0297 <LI>Command-based scoring is in Beta release; commands and methods are subject
0298 to modification in future releases. Feedback will be greatly appreciated.</LI>

0309 <UL>
0310 <LI>Improved simulation of the high-energy gamma tail for muon Bremsstrahlung
0311 (rare process, important for background simulation - NA49).</LI>

0313 becomes stable versus modification of the cut in range.</LI>

0318 <LI>Fixed problem reported by ATLAS of high energy collision of <TT>sigma+</TT>
0319 and a nucleon producing a high energy backward proton. This problem has
0320 been in the hadronic code since the beginning and was due to incorrectly
0321 selecting evaporated nucleons as leading particles. At <TT>1 TeV</TT>
0322 incident energy, this type of event occurred 0.5% to 1% of the time when
0323 the HEP models are used. After the fix, no high energy backward nucleons
0324 are observed, with the effect that such events will not exist to mimic
0325 exotic reactions.</LI>
0326 <LI>Bug fixes and completed implementation of theory in <TT>G4PreCompoundModel</TT>
0327 and <TT>G4Evaporation</TT> have produced a 10-15% increase in neutron flux
0328 for <TT>2.5 GeV/c</TT> protons incident on <TT>Pb</TT>.</LI>
0329 <LI>Correct time is now set for secondaries, instead of global time. This will
0330 primarily affect neutron times for users of the HP neutron package.</LI>
0331 <LI>An angular distribution bug in Bertini cascade has been fixed. Previously,
0332 double differential cross sections showed an excess of events at high
0333 energy and small to medium scattering angles. The fix removes this by
0334 using an <TT>exp(t)</TT> distribution for nucleon-nucleon scattering above
0335 <TT>2.8 GeV</TT>. This will result in only a small reduction of average
0336 particle energy in the secondaries.</LI>
0337 <LI>Bug fix in quasi-elastic scattering may cause shower shapes to be a bit
0338 shorter and wider when using QGSC/QGSP physics lists.</LI>

0373 The following message can be written to standard output at the end of a program:
0374 <PRE>
0375 G4Transportation: Statistics for looping particles
0376 Sum of energy of loopers killed:
0377 Max energy of loopers killed:
0378 </PRE>
0379 It provides the total energy (in <TT>MeV</TT>) of tracks killed due to
0380 excessive number of steps ('looping') during the simulation, and the maximum
0381 energy of such a track. Such behaviour can be due to looping in magnetic fields
0382 or encountering problems at geometrical boundaries.
0383 <P></P>
0384 In case either of these reported energy is significant, we recommend to
0385 increase the verbosity of <TT>G4Transportation</TT> to obtain information for
0386 each track killed. A user can change the threshold energy above which particles
0387 are not killed using the method <TT>SetThresholdImportantEnergy</TT> of
0388 <TT>G4Transportation</TT>. The default value is <TT>250 MeV</TT>.

0741 <UL>
0742 <LI>Modified behaviour of <TT>G4Navigator</TT>
0743 for small straight steps - when a track does less than the safety.
0744 Before only a simple, quick estimation of the starting point's safety was done, using the
0745 last available value of the isotropic safety (from the Navigator).
0746 Now the navigator is called to compute this safety. This improves the value
0747 and avoids roundoff issues. It gives better stability in comparisons with
0748 CoupledTransportation. The costs are additional calls to the Navigator.
0749 A new method <TT>EnableShortStepOptimisation</TT> controls this.
