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 8.3 to release 9.0.
0120 Note that a full re-installation of libraries (or a full recompilation) and
0121 a recompilation of user applications is anyhow required.
0122
0123 <P> </P>
0124 <B>Geometry</B>
0125 <P> </P>
0126 The static constants for the geometrical tolerance <TT>kCarTolerance</TT>,
0127 <TT>kRadTolerance</TT> and <TT>kAngTolerance</TT> which used to be defined
0128 at global scope, have been now removed.<BR>
0129 Advanced applications making use of such constants in the code are required
0130 to retrieve the values for Cartesian, Angular and Radial tolerances through
0131 the class <TT>G4GeometryTolerance</TT>, a new class providing the methods,
0132 respectively: <TT>GetSurfaceTolerance()</TT>, <TT>GetRadialTolerance()</TT>
0133 and <TT>GetAngularTolerance()</TT>. Applications with setups of unusual
0134 dimensions (e.g. smaller than <TT>1 mm</TT> or larger than <TT>1 km</TT>)
0135 can now adjust these values, and must do so before creating any part of
0136 the geometry description. Please see the User's Guide for Application
0137 Developers for the details.
0138
0139 <P> </P>
0140 <B>Biasing & Scoring</B>
0141 <P> </P>
0142 <UL>
0143 <LI>When defining a parallel geometry for importance biasing, the parallel
0144 geometry now must inherit from <TT>G4VUserParallelWorld</TT>. This
0145 has a <TT>GetWorld()</TT> method which creates a (named) copy of the mass
0146 geometry world volume and later retrieves it.</LI>
0147 <LI>The different parallel and mass sampler classes have been combined into
0148 one <TT>G4GeometrySampler</TT> class which requires the following
0149 instantiation, e.g.:
0150 <TT>mgs(detector->GetWorldVolume(),"neutron");</TT><BR>
0151 An additional set method defines whether or not the sampler is in a
0152 parallel geometry: <TT>mgs.SetParallel(false);</TT> </LI>
0153 <LI>When a parallel world is created, then parallel navigation must be activated. An application with physics list that uses the <TT>AddTransportation</TT> method will automatically use
0154 <TT>G4CoupledTransportation</TT> which is picked up by the creation of
0155 the parallel world copy.</LI>
0156 <LI>All scoring can be implemented only through the Primitive Scorer
0157 classes. Users utilising the older scoring classes will need to migrate to using Primitive Scorers. The same functionality is provided apart from G4ScoreTable, but scorers are now attached to logical volumes (in place of geometry cells).. This requires
0158 explicit copy numbers to be utilised for the same logical volume and the
0159 <TT>GeometryCell</TT> methods should be accessed through the physical
0160 volume <B>and</B> replica number method.</LI>
0161 <LI>A demonstration of the new biasing and scoring is available in
0162 <TT>examples/extended/biasing/B01</TT> and <TT>B02</TT>.</LI>

0169 A few methods of the interface classes <TT>G4VEmModel</TT>,
0170 <TT>G4VEnergyLossProcess</TT>, <TT>G4VEmProcess</TT>,
0171 <TT>G4VMultipleScattering</TT> were revised, in order to reduce memory
0172 allocations. All classes inheriting these interfaces were modified accordingly
0173 (see detailed list of changes). Advanced users with derived classes must make
0174 similar changes.
0175 </P>
0176 <P>
0177 Old implementations of physics processes, of configurations frozen in release
0178 5.2, have been removed (see below detailed list of changes).
0179 </P>
0180 An enumerator of step limitation algorithms of the multiple-scattering process
0181 has been introduced. It replaces a boolean value . The step limitation types
0182 are:
0183 <UL>
0184 <LI><TT>Minimal</TT> - equivalent to the original algorithm, as implemented in Geant4 7.1 and earlier releases.</LI>
0185 <LI><TT>UseSafety</TT> - the current default, which makes use of the geometrical safety</LI>
0186 <LI><TT>UseDistanceToBoundary</TT> - the most advanced, recommended for accuracy in the
0187 cases where no magnetic field is set.</LI>
0188 </UL>
0189 As in releases 8.0 to 8.2, the minimal option (which used to be called
0190 'no step limitation') results in fewer steps, and typically provides less
0191 stability than the other options.
0192
0193 <P> </P>
0194 <B>Hadronic physics</B>
0195 <P> </P>
0196 <UL>
0197 <LI>Isotope production counting flag is now set to OFF by default.
0198 If desired, user code must switch it on using the method
0199 <TT>G4HadronicProcess::EnableIsotopeCounting()</TT>.
0200 Isotope production models allow users to specify their own
0201 isotope production mechanism and data set, or use G4NDL to get
0202 the production cross sections. If no model is specified,
0203 the largest final state nuclear fragment becomes the produced
0204 isotope. If enabled, isotope production will occur for any
0205 hadronic model. Only users who have specifically assigned an
0206 isotope production model in their physics lists will be affected
0207 by tghe above change.</LI>
0208 <LI>The old variable <TT>NeutronHPCrossSections</TT> defining the path where
0209 to load the G4NDL data set has been renamed to <TT>G4NEUTRONHPDATA</TT>,
0210 so that this variable shares the G4 prefix used for other environment
0211 variables; therefore the user environment must be changed accordingly.</LI>
0212
0213 </UL>
0214
0215 <P> </P>
0216 <B>Physics Lists</B>
0217 <P> </P>
0218
0219 Removed physics lists <TT>LHEP_HP, QGSP_HP, LHEP_BIC, LHEP_BIC_HP</TT>
0220 and <TT>LHEP_PRECO</TT>, which were marked obsolete in release 8.2.
0221 Users are encouraged to evaluate <TT>QGSP_BIC</TT> as a replacement of
0222 <TT>LHEP_PRECO</TT> and <TT>LHEP_BIC</TT>. The list <TT>LHEP_BIC_HP</TT>
0223 is replaced by <TT>QGSP_BIC_HP</TT>. In place of the remaining lists
0224 (<TT>LHEP_HP, QGSP_HP</TT>) we suggest to evaluate <TT>QGSP_BERT_HP</TT>
0225 and <TT>QGSP_BIC_HP</TT>.<BR>
0226 Also removed physics lists using the <TT>Mars13</TT> leading particle classes,
0227 i.e. lists with a name containing <TT>_LEAD_</TT>.
0228 <P>
0229 The components for electro-magnetic physics have been renamed and three
0230 variants are now available:
0231 <UL>
0232 <LI><TT>G4EmStandardPhysics</TT> - the default</LI>
0233 <LI><TT>G4EmStandardPhysics_option1</TT> - providing similar physics to
0234 that implemented in release 7.1</LI>
0235 <LI><TT>G4EmStandardPhysics_option2</TT> - using <TT>sub-cutoff</TT>
0236 options, which enable lower production thresholds for delta-electrons
0237 near geometry boundary.</LI>

0269 <LI>The structure of UI commands was changed: a new directory
0270 <TT>/process/msc</TT> contains all commands for multiple scattering.
0271 New UI commands are added to control the parameters of the Multiple
0272 Scattering process:
0273 <UL>
0274 <LI><TT>/process/msc/Skin</TT></LI>
0275 <LI><TT>/process/msc/RangeFactor</TT></LI>

0278 <LI><TT>/process/msc/LateralDisplacement</TT>.</LI>
0279 </UL></LI>
0280 <LI>The interface to <TT>G4EmProcessOptions</TT> is modified to be consistent
0281 with this change.</LI>
0282 <LI>As a result, the possibility to change the values of parameters between
0283 runs is now extended to all parameters which can be defined via the UI.</LI>
0284 </UL>
0285
0286 <B>Hadronic physics: Neutrons</B>
0287 <UL>
0288 <LI>When using the high precision neutron module, a user may now choose to
0289 force the use of the Photon Evaporation model, instead of the neutron
0290 capture final state data. The environment variable
0291 <TT>G4NEUTRONHP_USE_ONLY_PHOTONEVAPORATION</TT> must be
0292 set to do this. For cases in which the final state data does not exist
0293 in the G4NDL data library, this model was already used and thus there is
0294 no change. </LI>
0295 <LI>A user can force high precison neutron code to use only exact isotope
0296 data files, instead of allowing nearby isotope files to be used. In this
0297 case if the exact file is not available, the cross section will be set to
0298 zero and a warning message will be printed. To enable this, set the
0299 environment variable <TT>G4NEUTRONHP_SKIP_MISSING_ISOTOPES</TT>.</LI>
0300 <LI>A user can switch off the Doppler broadening due to the thermal motion of
0301 the target nucleus. The broadening is used to correct the G4NDL data,
0302 which are at zero temperature. This must be done only for appropriate
0303 applications. To switch it broadening off, the environment variable
0304 <TT>G4NEUTRONHP_NEGLECT_DOPPLER</TT> must be set. Then the Doppler
0305 broadening in the cross section calculation is neglected. However, the
0306 thermal motion of the nucleus is still taken into account in the Final
0307 State Generator. This option provides a significant CPU performance
0308 advantage. It is not suitable, though, for simulation in which low energy (thermal)
0309 neutrons are important, as related observables are affected.</LI>

0321 <LI>Results for calorimetry are expected to be unchanged within 0.5%.
0322 The width of energy deposition in thin layers (vertex detectors) should
0323 be more close to data - current accuracy is few percent.</LI>
0324 <LI>In simple setups a speedup of simulation of EM showers of about 10%
0325 is observed for the 'default' EM physics configuration (used in most
0326 lists, including QGSP) and about 5% for the faster 'optional' physics

0332 <LI>The FTF model is now used in some physics lists down to <TT>5 GeV</TT>.</LI>
0333 <LI>Bug fixes in LEP models remove an un-physical peak at 180 degrees and
0334 reduce the number of very low energy nucleons produced. The net effect
0335 is to shift the angular distributions forward by about 5-10 degrees and
0336 increase the mean secondary kinetic energy by roughly
0337 <TT>20 - 30 MeV</TT>.
0338 Effects of this size occur at incident particle energies of
0339 <TT>2 - 10 GeV</TT>.
0340 At higher energies the effect is small. Benchmark tests show little
0341 change in shower shape.</LI>

0382 It provides the total energy (in <TT>MeV</TT>) of tracks killed due to
0383 excessive number of steps ('looping') during the simulation, and the maximum
