                   Geant4 9.3-beta-01 Release Notes
                   --------------------------------
 
                                                             5 June 2009
 
 List of main features and fixes included in this Beta release since 9.2.p01:
 
   o Configuration:
     -------------
     + Configure script:
       o Rewritten check on make/gmake on WIN32-VC systems to avoid problems
         with cygwin and Matlab.
       o Added check to build Qt driver only when Qt UI module is built;
         reordered 'moc' checks and added cross-check on moc version.
         Added safety reset of OpenGL QT build and use variables.
       o Commented out echo compatibility warning to address problem
         report #1067.
     + Corrections in analysis.gmk for AIDA setup on Windows.
     + Improved non-standard setup for Qt on Linux, Mac and Windows.
     + Removed "-lcxa -lunwind" LOADLIBS addition in Linux-icc.gmk,
       no longer necessary since icc version 11.0.083.
 
   o Digits & Hits:
     -------------
     + Replaced usage of non-Standard calls to sprintf() with ostringstream,
       to fix compilation errors reported by gcc-4.4.0 compiler.
 
   o Environments:
     ------------
     + G4Py: updated configuration scripts and some minor fixes.
 
   o Error Propagation:
     -----------------
     + Inclusion of pi+, pi- and proton in physics list.
     + Added possibility to account for error deflation
       (needed to make 'smoothing').
 
   o Geometry:
     --------
     + divisions:
       o Allow for generic divisions along Z for polyhedras and polycones; now
         divisions can happen along z-axis with width and offset, which fulfils
         the condition that division does not span over more than one segment.
       o Fixed initialization of division in Phi for polyhedras to avoid taking
         into account user defined width.
     + magnetic field:
       o Added 3rd term of BMT equation (Spin x Beta x Efield) to
         G4EqEMFieldWithSpin, as reported in the Emfield Hypernews Forum
         posting #155.
       o Moved renormalization of spin from G4EqEMFieldWithSpin and
         G4Mag_SpinEqRhs to G4ClassicalRK4 and G4SimpleHeum.
       o Added Spin propagation errors to the criteria for 'OneGoodStep' in
         G4MagIntegratorDriver; not added it yet to the decision logic.
       o Enhanced algorithm for ApproxCurvePointS() in G4ChordFinder speeding
         up Brent locator.
       o Some code cleanup and formatting.
     + management:
       o Fixed initialisation of min/max extent in method BuildReplicaVoxels()
         in G4SmartVoxelHeader.
       o Adopt 'const' references for strings as arguments/return-values in
         G4LogicalSurface. Some minor cleanup...
     + navigation:
       o Fix in G4Navigator::ComputeStep() for the computation of rotation of
         the 'LocalExitNormal' in cases when DistanceToOut() returns non-valid
         normal for optical photons in rotated solids.
         Addresses problem report #1059.
       o Fix in G4PathFinder: a geometry is at a boundary if its step is within 
         tolerance of the minimum step for any defined geometry.
       o Fix in G4PropagatorInField::SetNavigator() to forward new navigator to
         G4VIntersectionLocator. Corrects handling of parallel geometries.
       o Enhanced algorithm to speed up Brent intersection locator for propagation 
         in field.
       o Fix in the usage of the geometrical tolerance in G4VIntersectionLocator
         in method AdjustementOfFoundIntersection().
       o Added method BuildContainerSolid() taking a solid as argument to
         G4PhantomParameterisation. Added protection to GetMaterialIndex()
         for zero index.
     + solids/CSG:
       o Implemented speed improvements and corrections in G4Sphere from joint
         code review: cached computation for half-tolerances and use of Boolean
         flag for identifying if full-sphere, shell or section; implemented
         caching of trigonometric values, now directly computed inside modifiers
         for Phi and Theta angles as required for parametrised cases;
         rationalised usage of relative radial tolerances.
       o Implemented correction to G4Sphere::DistanceToOut(p,v, ...) for phi
         sections for rays passing through zero.
       o G4Tubs, G4Cons: rationalised usage of modifiers for Phi angles and
         simplified constructors.
     + solids/specific:
       o Corrected implementation of GetSurfaceArea() in base class G4VCSGFaceted, 
         which was erroneously returning cubic volume estimation. Addresses 
         problem report #1062.
       o Relaxed error condition in G4TessellatedSolid::Inside(p) to warning,
         for excess of max trials and anomalous conditions in distance
         calculation. Added more printout information when error condition is
         detected.
 
   o Global:
     ------
     + G4PhysicsVector: added method ComputeSecondDerivatives() for the case
       when user provides first derivative at end-points (4 bins minimum); 
       use "Not-a-Knot" algorithm for computing second derivatives 
       in default method FillSecondDerivatives() (5 bins minimum);
       for smaller number of bins the linear interpolation is used.
     + Added G4ErrorStage enum to G4ErrorPropagatorData class.
     + Changed date for release 9.3-beta.
 
   o Graphical Representations:
     -------------------------
     + G4VVisManager: added notify scene handlers (G4VGraphicsScene objects)
       which inform that the scene has changed, so that handlers can
       rebuild their graphics database (if it exists) and redraw all views.
     + G4VMarker: added enum 'SizeType' {none, world, screen};
       added GetSizeType() and SetSize/Diameter/Radius() methods.
 
   o Intercoms:
     ---------
     + G4UIcommandTree: improved completion of commands for GUIs by sharing 
       code of X and Xm drivers with the Qt driver.  
 
   o Interfaces:
     ----------
     + G4UIExecutive: new class for automatic instantiation of user interactive
       sessions.

   o Materials:
     ---------
     + Implemented migration of ICRU 73 stopping power classes to the
       G4VIonDEDXTable interface:
       o Access methods of physics vectors have changed (vectors can also be
         identified via atomic number of material if material is pure);
       o Classes now deliver mass stopping powers instead of stopping powers
         per unit length
       o Dependency on ICRU 73 material densities was removed (no densities
         are included in the classes anymore).
       o Stopping power vectors are now built on request.
     + G4IonStoppingICRU73: extended upper limit of the data vector from
       10 MeV to 1 GeV, using 53 bins; added G4WATER data and fixed GetDEDX()
       methods in these classes for E=10 MeV (upper limit).
     + G4NistMaterialBuilder: mean ionisation potential for G4_WATER is changed
       to 78 eV according to GSI Annual Report (2008) p.373, in order to be
       consistent with ICRU'73 tables.
     + Fixed ICRU'73 data for G4WATER, G4WATER_VAPOR, G4NYLON-6/6 (in
       G4MaterialStoppingICRU73) and G4_Cu (in G4SimpleMaterialStoppingICRU73).
     + New utility class G4ExtDEDXTable to handle external electronic
       stopping power tables for ions.
     + Use 'const' references for strings as arguments/return-values in material
       properties tables and related classes. Inlined methods and minor cleanup.
     + Added Entries() method to G4MaterialPropertyVector and accessors for maps
       in G4MaterialPropertiesTable, required for internal use in persistency of
       material properties. Make visible GetEntry() accessor in
       G4MaterialPropertyVector for use restricted to persistency.
 
   o Particles:
     ---------
     + Added method GetNuclearMass(A,Z) in G4NuclearProperty.
     + Use new class G4NucleiPropertiesTableAME03 for atomic masses. Including 
       data updated to the Ame-2003 atomic mass evaluation (II) by G.Audi, 
       A.H.Wapstra and C.Thibault, Nuclear Physics A729, 2003.
     + Ensure that the boost beta value is less than 1 in
       G4MuonRadiativeDecayChannelWithSpin.
     + Added CalculateAnomaly() method for magnetic moment in
       G4ParticleDefinition.
     + Fixed use of std::fabs() in place of std::abs().
 
   o Persistency (GDML):
     ------------------
     + Correction in materials and solids tags to allow parsing of
       definitions within the tag scope; possibility foreseen by the schema.
     + Correction in G4GDMLWriteSolids::BooleanWrite() in order to handle
       cases of nested displaced solids given to both operands in a Boolean
       operation (ATLAS use case).
     + Implemented virtual layer to allow customisation of the writer for
       user-extended schemas.
     + Implemented ability to write surface properties associated to volumes
       and material properties.
     + Allow for reading/writing of constant material properties.
     + Defined missing copy constructor and operator=() to G4GDMLMatrix
       internal class, to avoid cases of memory corruption when handling
       matrices.
     + Restricted usage of loops only for placement of volumes. Now correctly
       handles most common use-case of multiple copies of the same volume/solid
       through loop statement. Addressing problem report #1063.
     + Renamed flag for maximum number of transformations applied to a solid
       and moved to G4GDMLWriteSolids base class.
     + Code cleanup: rationalised inclusion of headers, replacing them with
       forward declarations where possible.
     + Added empty default constructor and virtual destructor to classes in the
       inheritance chain.
 
   o Physics Lists:
     -------------
     + Added builders for DNA, Livermore and Penelope physics processes.

       with FTFP, and transitioning from BERT to FTFP between 7 and 9 GeV.
     + Added FTFP_BERT_TRV as variant of FTFP_BERT with transition between
       6 and 8 GeV.
     + Added MaxEnergy() method in FTF builders.
     + Added two new physics lists QGSC_QGSC and QGSC_CHIPS.
       QGSC_QGSC physics list uses the QGS model with the MultiSoft
       interface to CHIPS at all energies, starting from E=0. For neutrons
       it still uses LEP (LHEP) models for the radioactive capture and fission.
       QGSC_CHIPS physics list uses the QGS model with the EnergyFlow
       interface to CHIPS at all energies. For the pA interactions the
       native CHIPS process G4QCollision is used below 290 MeV. The QGSC and
       G4QCollision processes are unified in one process by the CHIPS
       G4QDiscProcessMixer interface. Added the corresponding physics builders.
     + Added new physics-lists with special EM options: FTFP_BERT_EMV,
       FTFP_BERT_EMX, QGSP_BERT_EMX, QGSP_BIC_EMY (opt3 EM physics).
     + Declared obsolete several unused lists, partially disabling their use:
       o Obsolete and disabled:
           FTF_EMV,   replacement FTFP_BERT_EMV
           QGSC_EFLOW, replacement QGSC_CHIPS

       o Obsolete:
           FTFC, LHEP_BERT, LHEP_BERT_HP, LHEP_PRECO_HP

           QGSP_NQE, QGSP_QEL  
     + G4PhysicsListFactory: updated list of supported PhysLists.
     + G4EmStandardPhysics, G4EmStandardPhysics_option1: use 9.2 msc model
       for e+-.
     + G4EmStandardPhysics_option2: use G4WentzelVIModel for e+/e-.
     + G4EmStandardPhysics_option3: use updated multiple scattering model
       G4UrbanMscModel2 and G4RayleighScattering process.
     + Fix in G4HadronInelasticQBBC: cross sections are created dynamically
       not by value, fission only instantiated for HP.
     + Fix to address problem report #1056: all cross section data sets are
       created dynamically and no longer member of the class.
     + Inline constructor and destructors are moved to source for classes:
       G4VNeutronBuilder, G4VPiKBuilder, G4VProtonBuilder, G4WarnPLStatus.

       o Added G4PenelopeBremsstrahlungModel, namely Bremsstrahlung according
         to Penelope model, inheriting from G4VEmModel. Completes migration 
         to common 'Standard' design for all Penelope processes.
       o Added G4RayleighScattering process to describe Rayleigh scattering
         and removed G4Rayleigh class to avoid duplication.
       o Added G4LivermoreIonisationModel, first implementation of
         LowEnergyIonisation in the common design.
       o Updated public interface of G4eIonisationCrossSectionHandler in order

         from existing ICRU 73 data). Included algorithm in ion model,
         G4IonParametrisedLossModel, extending its applicability to very heavy 
         ions.

       o Some code cleanup: improved comments, avoid inlined virtual methods.
     + Polarisation:
       o Simplified initialisation in G4PolarizedAnnihilationModel.
     + Standard:
       o G4UrbanMscModel2: new tuning for the central part and for the tail of
         the angular distribution using the old e- scattering data only
         (Phys. Rev. 84 (1951) 634; Phys. Rev. 61 (1942) 254); new version of

       o Simplified initialisation of all models and some code cleanup: improved
         comments, avoid inlined virtual methods.
       o G4UniversalFluctuation: modification in width correction, the

       o G4PairProductionRelModel: new relativistic model for gamma conversion.
       o G4PEEffectModel: substitute ComputeMeanFreePath() by
         CrossSectionPerVolume() resulting in minor CPU speedup for compound
         materials.
       o G4PAIModel, G4PAIPhotonModel: removed usage of random numbers at

         and gamma.
       o For rare cases of the output hadron mass below the GS mass avoid
         exception in the G4QEnvironment class; use 'As-Is' filling for the
         hadron with appropriate warning.
       o Cleared warning in elastic scattering for low energy nHe and pHe
         reactions.
       o Added safety check of 'nDelta' in the hadronization probability

     + models/parton_string/hadronization
       o Changed pt sampling in G4LundStringFragmentation to avoid near endless
         loop; this should improve overall performance slightly.
         Addresses problem report #1066. Affected G4VLongitudinalStringDecay,
         where SampleQuarkPt() is implemented; added new optional argument of
         max Pt to SampleQuarkPt().
       o Removed warning in G4ExcitedStringDecay for applying QGSC from zero
         energy.
     - models/parton_string/qgsm

         of  anti-diquark & antiquark; note the reverse order, too. 
         Fixes problems with incident anti-baryons, e.g. anti-proton,
         manifesting in problems with forming hadrons.
       o Modifications in G4GammaParticipants and G4QGSParticipants for
         applying QGSC from zero energy.

         G4RPGInelastic and replaced with local array. Fixed issues of wrong
         order for static initialization.
     + models/theo_high_energy
       o Quasi Elastic part is used in QGSC at low energies to improve
         the performance of QGSC at low energies.
     + processes
       o Fix to address problem report #1056: cross section data set now are
         created dynamically in G4PhotoNuclearProcess, G4ElectronNuclearProcess
         and G4PositronNuclearProcess.
       o Moved inline constructor and destructors to source in class
         G4PositronNuclearProcess.

         the reflectivity every time for DielectricMetal, and do not
         re-calculate normal to facet; also fixed possible infinite loop by
         resetting iTE and iTM inside GetReflectivity().
       o Added exception for cases where invalid normal is returned; following
