0116 <LI>The new version of CLHEP can be built supporting the C++11 Standard,
0117 on compilers that support C++11.
0118 When C++11 option is chosen in a multi-threaded build of Geant4,
0119 this trigers the use of the Standard <TT>thread_local</TT>
0120 and <TT>atomic</TT> keywords.</LI>
0121 <LI>The procedure of deleting the full geometry for rebuilding a new one from
0122 scratch has been reviewed. It is suggested to use
0123 <TT>G4RunManager::ReinitializeGeometry(<I>true</I>)</TT>
0124 or the equivalent UI command <TT>/run/reinitializeGeometry</TT> rather than
0125 directly invoke deletion from G4SolidStore, G4LogicalVolumeStore and

0189 <A HREF="https://cern.ch/aidasoft/USolids">Unified Solids Library</A>
0190 primitives, to replace the original Geant4 solids, as in the

0197 <LI>Preliminary support for phonon propagation
0198 (see <A HREF="#phonon"><b>Phonon Physics</b></A> below) is provided
0199 by G4LatticeLogical (which defines parameters for materials) and
0200 G4LatticePhysical (which associates G4LatticeLogical with a particular
0201 G4VPhysicalVolume, including lattice orientation). These objects should
0202 be instantiated in the user's G4VUserDetectorConstruction class.</LI>
0203 </UL>
0204
0205 <B>Electromagnetic physics</B>
0206 <UL>
0207 <LI>A new class G4EmParameters and updated set of UI commands have been
0208 introduced, allowing easy definition of the EM parameters both in
0209 sequential and multi-threaded modes.</LI>
0210 <LI>A new option "DisplacementBeyondBoundary" for simulation of
0211 multiple scattering diplacement at geometry boundary is available.</LI>
0212 <LI>G4SynchrotronRadiation process is now applicable for all
0213 charged particles.</LI>
0214 <LI>High energy processes G4GammaConversionToMuons and G4eeToHadrons
0215 are ready for production.</LI>
0216 <LI>A new model class G4LowEWentzelVIModel is introduced for low-energy
0217 electron elastic scattering. Low-energy cross-section for water has
0218 been added for the low-energy Livermore photoelectric model.</LI>
0219 <LI>A new User Interface command to disable production
0220 thresholds in atomic deexcitation has been introduced:
0221 <TT>/process/em/deexcitationIgnoreCut true/false</TT>.</LI>
0222 <LI>An alternative set of data files for the simulation of atomic fluorescence
0223 lines is also provided in this release.</LI>
0224 <LI>In Geant4-DNA physics, added ionisation model from Rudd for
0225 B, Be, Li and Si ions. An alternative physics constructor
0226 G4EmDNAPhysics_option1 including the G4LowEWentzelVIModel has been also
0227 introduced. G4DNAIonisation and G4DNARuddIonisationExtendedModel have been
0228 updated for G4GenericIon usage.</LI>
0229 <LI>Classes for the simulation of water radiolysis have been introduced for
0230 Geant4-DNA chemistry.

0234 <B>Hadronic physics</B>
0235 <UL>
0236 <LI>In this release, mass width is taken into account in decays of short-lived
0237 hadrons. Daughter hadrons have dynamical mass according to Breit-Wigner
0238 distribution.</LI>
0239 <LI>The Fritiof (FTF) model has been significantly improved, resulting in
0240 closer agreement with thin-target data.
0241 Revisions in string fragmentation affect the meson production, and in
0242 particular the pi-zero fraction of showers. This is largely counteracted
0243 by other improvements of FTF and an imposed reduction of omega production.
0244 The overall effects on hadronic observables is found to large cancel
0245 in our benchmark hadronic calorimeter setups, but the effect should be
0246 monitored on experiment setups for key observables including visible
0247 energy, resolution, longitudinal and lateral size.</LI>
0248 <LI>The fragmentation part of the Quark-Gluon-String (QGS) model has been
0249 improved significantly.
0250 This implies that the hadronic showers produced with QGS-based physics
0251 lists (e.g. QGSP_FTFP_BERT) become wider and longer, and with a lower
0252 energy response, in closer agreement with the ones produced by FTF. </LI>
0253 <LI>The INCLXX model has been extended up to 15-20 GeV incident energy.</LI>
0254 <LI>Labeling of tracks resulting from muon stopping are added.</LI>

0260 <UL>
0261 <LI>A new set of processes and utility classes are provided as a framework
0262 to support propagation of phonons through materials.</LI>
0263 <LI>G4LatticeManager and G4LatticeReader provide access to the solid
0264 crystal structure parameters (G4LatticeLogical and G4LatticePhysical in
0265 Materials) read from data files and used by the physics processes.</LI>
0266 <LI>G4PhononPolarization defines an enum to identify the three acoustic
0267 phonon polarization states supported in this framework. See
0268 also <A HREF="#particles"><b>Particles</b></A> below.</LI>
0269 <LI>G4PhononTrackMap is an internal singleton class used by the processes
0270 to associate additional phonon-specific information (wave number,
0271 etc.) with each propagating G4Track object in the event.</LI>
0272 <LI>G4VPhononProcess is the abstract base class for the phonon processes,
0273 and provide some common utility functions.</LI>
0274 <LI>G4PhononDownconversion implements the conversion of high energy
0275 phonons to pairs of lower energy phonons.</LI>
0276 <LI>G4PhononReflection is a "template" process which will, in the future,
0277 implement reflection or transmission of phonons at the boundaries of
0278 crystals. Currently, phonons at a boundary are absorbed, and an
0279 associated G4VUserSteppingAction (in the <Code>phonon</Code> example)
0280 records hits.</LI>
0281 <LI>G4PhononScattering implements the scatting of phonons from one
0282 polarization state to another due to impurities or defects in the
0283 crystal lattice.</LI>
0284 </UL>
0285
0286 <B>Generic Biasing</b>
0287 <UL>
0288 <LI>A new class G4BiasingProcessSharedData is introduced, allowing to gather
0289 information shared by the G4BiasingProcessInterface instances attached
0290 to the same G4ParticleDefinition (hold by a same G4ProcessManager).</LI>
0291 <LI>Now providing easier access to cross-sections/mean-free-paths of wrapped
0292 physics processes, making all them up to date at the first call to the
0293 biasing operator.</LI>
0294 <LI>New examples have been added: <TT>GB03</TT> showing a technique inspired
0295 by geometry importance biasing, but with some more flexibility;
0296 <TT>GB04</TT>, an implementation of Bremsstrahlung splitting, using the
0297 generic biasing classes.</LI>

0305 <LI>Pre-instantiation of all ions and isomers is still optional via a UI
0306 command at <TT>PreInit</TT> or <TT>Idle</TT> states.</LI>
0307 <LI>Three new particles corresponding to the polarization states of acoustic
0308 phonons are provided to support the <A HREF="#phonon">phonon physics</A>

0323 <LI>The physics lists based on INCLXX use this model for pions, protons and
0324 neutrons up to 20 GeV, and the string model (FTF or QGS) starting
0325 from 15 GeV.</LI>
0326 <LI>Trying out a new hadron elastic scattering, still in development, in

0889 <LI>Simplified the G4VBiasingOperation interface class:
0890 <UL>
0891 <LI>Suppressed DenyProcessPostStepDoIt() method, functionality
0892 merged (and generalized) in ApplyFinalStateBiasing().</LI>
0893 <LI>Extra argument added as last argument of

0897 not changing the primary state, changing its weight, and

0906 <LI>Introduced G4BiasingProcessSharedData: a class that gathers
0907 information shared by G4BiasingProcessInterface instances attached
0908 to the same G4ParticleDefinition (hold by same G4ProcessManager).
0909 Access to the object is provided by the G4BiasingProcessInterface
0910 methods GetSharedData().
0911 Provides in particular lists of G4BiasingProcessInterface instances
0912 for physics/non-physics biasing.</LI>
0913 </UL></LI>
0914 <LI>Easier access to cross-sections/mean-free-pathes of wrapped
0915 physics processes: this is done by a call to the
0916 PostStepGetPhysicalInteractionLength() of the wrapped physics
0917 processes that anticipates the call by the stepping manager:
0918 the first G4BiasingProcessInterface in the
0919 PostStepGetPhysicalInteractionLength() loop triggers these
0920 calls, and results are cached in each G4BiasingProcessInterface
0921 instance. This makes cross-sections of physics wrapped processes
0922 up to date at the first call to the biasing operator, simplifying
0923 biasing implementations dealing with several cross-section or the
0924 total cross-section.</LI>

0939 <LI>G4OpBoundaryProcess now allowing for Transmittance, Reflectivity and
0940 Absorption on dielectric_dielectric and dielectric_metal boundaries.
0941 Added ConstProperty "SURFACEROUGHNESS". If set, the reflectivity at

0943 <TT>exp(-pow((4*pi*theSurfaceroughness*Rindex1*cost1/wavelength),2))</TT>
0944 for <TT>Rindex1 > Rindex2</TT>.</LI>
0945 <LI>G4OpRayleigh process now calculates the Rayleigh scattering length for
0946 more materials than just Water (although the Water default is kept).

2195 <LI>Completely updated PhysicsLists: G4EmStandardPhysics_option4 substitutes
2196 option3 builder, as most accurate physics. Defined new physics-list,
2197 HADRONTHERAPY_1 specifically implemented for this application, defined as
2198 a collection of builders and very similar to the QGSP_BIC_HP; differs in
2199 the followings: contains G4EmStandardPhysics_option4 in place of
2200 G4EmStandardPhysics; contains the builder G4RadioactiveDecayPhysics.
2201 The defaults for the physics models are now complete and they corresponds
2202 to the HADROTHERAPY_1 apart for: G4HadronPhysicsQGSP_BIC, used in place of
2203 G4HadronPhysicsQGSP_BIC_HP; G4HadronElasticPhysics used in place of
2204 G4HadronElasticPhysics_HP
