3. Items for migration of the user code

• Changed default multiple scattering models to G4UrbanMscModel93 for electrons and positron, G4WentzelVIModel for muons. G4UrbanMscModel90 remains the choice for other particles.
• Removed obsolete classes G4MultipleScattering, G4UrbanMscModel and G4UrbanMscModel2. The use of multiple scattering processes specialised by particle type (G4eMultipleScattering, G4hMultipleScattering and G4MuMultipleScattering) is now mandatory.

• The Geant4-DNA G4DNAEmfietzoglouExcitationModel class for the modeling of electron excitation in liquid water is obsolete and should be replaced by the G4DNABornExcitationModel class.

• GDML: to better match the schema definition, a correction to the 'value' type from double to string has been made for the auxiliary-information returned by G4GDMLParser. This may require related change in the user code, where the auxiliary information feature is used.

• Previously obsolete physics lists have been deleted, for the detailed list please see below.
• Introduced new constructor for all builders with a common signature. Previous constructors are kept for this release, but are declared obsolete. They will be removed in a future release.

• The visualization trajectory modeling command /vis/modeling/trajectories/create/drawByParticleID used to default all trajectories to grey, with the user having to explicitly set any other color code. While the user can still set any wished color code, the default has been improved to: [e-/red; e+/blue; proton/cyan; gamma/green; neutron/yellow; pi+,pi-,pi0/magenta; other/grey].
• In some examples, visualization that used to draw trajectories as simple lines now also draws step points. Users who wish to disable step point drawing can do so by commenting out a line in the visualization macro.

• G4NEUTRONXS-1.0, new data set for evaluated neutron cross-section data on natural composition of elements (controlled by variable G4NEUTRONXSDATA).
• G4PII-1.2, new data set for shell ionisation cross-sections (controlled by variable G4PIIDATA).
• New data set versions: G4EMLOW.6.19, G4RadioactiveDecay.3.3, G4PhotonEvaporation.2.1, G4NDL.3.14.

4. New Developments and Capabilities

• It is now possible to introduce gaps between slices in divisions, by making use of a new specialised physical-volume type, G4ReplicatedSlice for defining the divided daughter volumes.
• In regular voxelised geometries, the restriction for voxels to completely fill the envelope container is now relaxed. It is now allowed to define envelopes of different types other than box for regular geometries, by making use of a new parameterisation helper class G4PartialPhantomParameterisation.
• A new specific shape, G4GenericTrap, is now implemented. This new solid represents an arbitrary trapezoid with up to 8 vertices standing on two parallel planes perpendicular to the Z axis.

• Introduced new UI commands from the GDML parser to allow for importing and exporting GDML files through macros or interactively, supporting all various options provided by the parser.

• Cylindrical scoring mesh is now fully released.
• Most of primitive scorers now take their default units, and units may by altered by their UI commands. These units are used for drawing and dumping the scores.

• New model G4ICRU73QOModel is available for low-energy ionisation of negative-charge projectiles (including anti-ions); it is based on ICRU'73 data for oscillator strengths; this model is the default for negative-charge particles in G4hIonisation process class.
• Improved modeling of fluctuations in energy deposition, relevant for deposit in gasses and silicon. Increases stability when step size changes.
• New model of single scattering and NIEL for ions G4IonCoulombScatteringModel is available; the model is applicable from 50 keV to 100 TeV.
• New ionisation models G4BraggIonGasModel, G4BetheBlochIonGasModel are available for simulation of ion transport in low density media, e.g. in vacuum. The ion charge of a particle is not changed by these models.
• The default angular distribution of gamma in the Bremsstrahlung process can be substituted by alternative model in physics-list.
• Fluorescence and Auger electron production can be activated via UI commands, using the new models G4PEEffectFluoModel and G4KleinNishinaModel.
• Disabled usage of minimum energy threshold per model. As a result the production threshold is defined only by range (converted to energy in each material). It remains constrained by the minimum limit defined in 'cut' category. This change is necessary to allow the full set of combinations of models in a process.

• Photon Livermore models: first implementation of pair production in the electric field of the electron. The G4BoldyshevTripletModel should be used in conjunction with the G4LivermoreNuclearGammaConversionModel model (using G4MultiModel) in order not to account twice for the pair production cross section in the electron field.
• Electron Livermore models: G4LivermoreIonisationModel is able to generate fluorescence along the step. Addressing problem report #1141.
• Penelope models: added four new models (gamma ray models: Compton, GammaConversion, PhotoElectric and Rayleigh). Upgrades of Penelope from version 2001 to version 2008, named as G4Penelope08xxxxModel. To be considered as beta.
• For all low energy EM models: no customized production cuts are allowed anymore for fluorescence/Auger. Main cuts from the G4ProductionCutsTable are always used, for consistency.
• Geant4-DNA (in liquid water):
  • New process and model classes for electron attachment and vibrational excitation.
  • New electronic excitation model for electrons.
  • Extended very low energy coverage of Champion's electron elastic scattering.
  • New excitation model for neutral hydrogen.
  • Preliminary new ionization models for C, N, O and Fe. To be considered as beta.
  • Multi-scale combination of Geant4-DNA discrete processes with Standard or low energy EM physics processes adopting the unified software approach of both EM physics sub-categories (see the microdosimetry advanced example for illustration).

• Hadronic interfaces now require integer Z and A arguments. Elements or materials with effective or average values of Z and A are no longer allowed.
• Quark exchange, Reggeon cascade and nuclear destruction parameters in the FTF model were tuned. Tuning of the nuclear destruction parameters was based on HARP-CDP data. Low mass string fragmentation was improved.
• The Bertini cascade model was re-written to employ more code re-use, improve memory management, and provide better energy/momentum conservation. Angular distributions of the two-body final states of hadron-nucleon interactions were redone and improved. An optional interface to the G4Precompound model (and the associated de-excitation processes) is now available; this is an alternative to the dedicated de-excitation which has been used until now.
• Anti-baryon-nucleon elastic scattering was added to the CHIPS model.
• Fermi breakup was extended to include fragments with 1 < A < 5 . Several improvements were made to bring the model closer to the original one of Botvina. Use hybrid of Fermi breakup and GEM models for A < 20. Several other improvements were made to the evaporation models. A README file was added explaining the photo-evaporation data files.
• New, fast models and cross sections for neutron elastic, inelastic and capture are now available: G4NeutronElasticXS, G4NeutronInelasticXS and G4NeutronCaptureXS.
• An isomer decay table was added to extend the number of existing isomers in the radioactive decay model. All of them will be decayed by isomeric transition (IT). A README file was added to explain the radioactive decay data files.
• RQMD (relativistic quantum molecular dynamics) code was enabled in the QMD model to allow treatment of higher collision energies.
• A new model, G4NuclNuclDiffuseElastic is now available for nucleus-nucleus elastic scattering.
• A new class G4ComponentAntiNuclNuclearXS provides the total elastic and inelastic cross sections of anti-nucleon and anti-nucleus interactions with nuclei. These were calculated using the Glauber approach.
• All hadronic processes now check to see if the cross section has become negative at the end of a step, before invoking the model.
• Checking of Energy/momentum conservation is available in the hadronic process class. Methods can set the theshold level for reporting and the verbosity of the output.

• New physics lists QGSP_BERT_CHIPS and Shielding, details are described below.
• Improved inelastic hadronic cross section at high energies, above 90 GeV, in all QGS.. and FTF.. lists.
• Improved cross sections for Kaon, and all "misc" particles, including anti-proton, anti-neutron, and hyperons in FTFP_BERT, QGSP_FTFP_BERT, and the two new physics lists QGSP_BERT_CHIPS and Shielding.
• Use G4UrbanMscModel93 by default for e+,e- in all EM physics builders except G4EmLivermorePhysics and G4EmPenelopePhysics where new G4GoudsmitSaundersonMscModel is used.
• G4WentzelVIModel93 and G4CoulombScattering are used by default for mu+,mu- in all builders.
• In G4EmStandardPhysics_option2 for small angle multiple scattering G4WentzelVIModel93 is used for protons, pions, and kaons; for angular distribution of bremmstrahlung gamma G4GeneratorBS is applied.
• Improved G4EmConfigurator class, to define alternative models by particle type, energy range, and detector region. Can be used to choose configuration EM models before or after the EM physics has been instantiated.

5. Expected effects on physics and performance

• Small increase of visible energy deposition in sampling calorimeters (e.g. 0.5% for a simplified setup with materials of the ATLAS EM barrel calorimeter) due to improvements in the multiple scattering model.
• Improved tails of energy deposition in thin absorbers.

• Improved treatment of low mass strings in the FTF model allows the model to be used at lower energies and provides a smoother transition in energy response in the region where string models give way to cascade models.
• Improved memory management in the Bertini cascade model results in a 10-fold reduction of object creation and destruction. The model also conserves energy and momentum better.
• Fermi Break-up Model and GEM evaporation are used by default providing improved production of light fragments in nuclear fragmentation at low energy.
• Improved spectra of nuclear gamma deexcitation including Doppler broadening simulation.
• Fast neutron cross-sections can provide significant CPU savings for applications which need accurate simulation of neutrons below 20 MeV.
• Materials defined with an effective Z or A can no longer be used with hadronic processes.

  • LBE: substituted obsolete G4MultipleScattering by particle wise processes. Updated to comply with the new EM design (use Livermore models rather than LowEnergy processes).
  • QBBC: disabled multi-fragmentation model of deexcitation.
  • QGS_BIC and FTF_BIC now use G4NeutronXS cross sections.
• G4DataQuestionaire: fix for problem report #1125 for optical physics, to correctly check on G4REALSURFACEDATA path.
• Added check on new G4NEUTRONXSDATA data set for QBBC and in G4NeutronCrossSectionXS.

• Added G4ScoreSplittingProcess if geometry includes a regular structure.
• Added protection against particle without process manager.
• Introducing two new methods in G4RunManager class, ReOptimize() and ReOptimizeMotherOf(); these will cause re-optimization (re-voxelization) of one particular logical volume without forcing re-optimization of the entire geometrical hierarchy.
• G4RunManagerKernel: in RunInitialization(), notify G4VisManager when geometry needs to be closed.

• Added G4Track::GetParticleDefinition() returning 'const' pointer, if possible.
• Added warning exception if GetDeltaEnergy/Momentum() methods are invoked. These methods are now obsolete and planned to be removed.
• Added touchable history of the origin to G4Track.

• Fixed restoring of output settings in G4SteppingVerbose. Fixed cases of restoring cout/cerr precision formatting in several classes.
• Use 0 instead of NULL where applicable.
• Fixed minor reports from Coverity.

• Management
  • Added new /vis/open command for OpenGL viewers, /vis/open OGL. This new form allows the same macro to be used whether one is on Linux or Windows (calling OGLSX on Linux and OGLSWin32 on Windows). When the application has been built with Qt, it will use the Qt form of OpenGL; when built with Motif, it will use the Motif form of OpenGL. Also added options OGLI and OGLS to force Immediate or Stored modes. The user is still free to use the older, specific viewer names, such as OGLIX, but the simple form, OGL, will give the most portable macros.
  • Added new /vis/open command for OpenInventor, /vis/open OI. This new form allows the same macro to be used whether one is on Linux or Windows (calling OIX on Linux and OIWin32 on Windows).
  • Added /vis/scene/add/digis and /vis/filtering/digi commands, analogous to the already-existing commands /vis/scene/add/hits and /vis/filtering/hits. As with hits, it remains the user's responsibility to provide the digitisation classes. Added method AddCompound(const G4VDigi&) to drivers.
  • Introduced DispatchToModel without i_mode. The archaic form G4VTrajectory::DrawTrajectory(i_mode) is replaced by the newer form, G4VTrajectory::DrawTrajectory(). i_mode used to be a parameter to control whether the trajectory was drawn as a line, a line plus step points, or only step points:
    • 'i_mode > 0' meant draw lines and points, size of points in 'pixels = abs(i_mode)/1000'
    • 'i_mode = 0' meant draw only lines
    • 'i_mode < 0' meant draw only points, size of points in 'pixels = abs(i_mode)/1000'
    Since release 8.1, better control has been available from the command /vis/modeling/trajectories. Since release 5.0, i_mode less than 1000 has in fact drawn no points and i_mode of 1000 has drawn points that were so small (a single pixel wide) that they were overshadowed by the trajectory itself except at endpoints of the trajectory or where the trajectory made a sharp change of direction. Use of i_mode is now trapped and a warning gets printed.
