2. Outline Major features introduced in release 10.0 – Geometry – Kernel & Interfaces – Visualization – Multi-threading (see talk by A.Dotti) – Physics (see talks by V.Ivantchenko and A.Ribon)  Detailed release notes: http://geant4.cern.ch/support/ReleaseNotes4.10.0.html  All planned features for 2013: http://geant4.cern.ch/support/planned_features.shtml 10 December 2013G.Cosmo - Geant4 release 10.0 highlights - kernel modules 2

3. Geant4 10.0 First major release since 2007 Important modifications introduced to most classes – Adaptations to thread-safety for event-level parallelism Additional API for user-action classes Backwards compatible with old API in sequential mode Major revision of internal data initialisation in all areas Reviewed memory management Possibility to install/run Geant4 either in pure sequential or parallel (MT) mode – Choice at configuration/installation time – Sequential mode set as the default New and extended features Removal of obsolete/deprecated code and interfaces 3  May imply changes/adaptation to user’s code 10 December 2013G.Cosmo - Geant4 release 10.0 highlights - kernel modules

4. Geometry 10.0 features Replaced UI commands for geometry overlaps check – Now based on built-in overlaps checking for random points generated on solids’ surfaces – Now consistently working also for parameterised volumes – Possibility to tune resolution for the test and set tolerances – Possibility to define depth interval in geometrical tree 4 Introduction of gravity field and magnetic field gradient Use of precise safety computation by default in navigation Introduced G4GenericPolycone for polycones with non monotonic vertices along Z for inner and outer surfaces Archived obsolete BREPs classes and module 10 December 2013G.Cosmo - Geant4 release 10.0 highlights - kernel modules

5. Geometry Geometrical primitives AIDA Unified Solids library integration AIDA Unified Solids library – As optional component, for replacing the original solids (G4GEOM_USE_USOLIDS flag) Provides optimised implementation for a large number of geometrical primitives and constructs – Included in Geant4 10.0:  box, orb, sphere (+sphere section), tube (+cylindrical section), cone (+conical section), simple trapezoid, tetrahedron, polycone, polyhedra  A shape can also be adopted individually by directly using provided G4Uxxx wrapper classes 510 December 2013G.Cosmo - Geant4 release 10.0 highlights - kernel modules

6. Physics Lists Removed physics-lists based on the CHIPS package – e.g. CHIPS, QGSC_BERT) Removed physics-lists based on the parameterized (Gheisha-like) models LEP/HEP – e.g. LHEP – LEP now replaced by Fritiof and/or Bertini models Updated physics lists combinations and options 10 December 2013G.Cosmo - Geant4 release 10.0 highlights - kernel modules6

7. More features … Highlights 7 Automatically generating isotope vector with natural abundances (NIST materials) Variables shadowing … Units & constants inclusion New framework for “generic” biasing for physics-based biasing Based on wrapper and helper classes Adoption of fast mathematical functions for exp() and log() Extracted from VDT library & adapted Expected CPU performance improvements 10 December 2013G.Cosmo - Geant4 release 10.0 highlights - kernel modules New minimal framework for low-temperature “phonon” physics Including acoustic phonon particle types, container classes for lattice dynamical constants, and processes for propagation and scattering of phonons, and anharmonic downconversion

8. More features … Visualization & Analysis Improved Qt support & GUI – Porting to Qt5 Ability to display in MT and sequential mode GL with no graphics card – To use for automated tests or launch GL graphics from batch Visualisation from web browser with Wt – Alpha version 8 Redesigned interfaces for analysis/histogramming – multi-thread capable 10 December 2013G.Cosmo - Geant4 release 10.0 highlights - kernel modules

9. External libraries and data sets Updated to adopt new CLHEP version 2.1.4.1 – Added RandGaussZiggurat and RandExpZiggurat distributions. – Added new units for Radioactivity kilo/mega/gigabecquerel, milli/microcurie. – Still compatible with older CLHEP releases New data sets: – G4ENSDFSTATE-1.0, data set for properties of nuclides state from Evaluated Nuclear Structure Data File Optional and controlled by G4ENDFDATA environment variable for path – G4ABLA-3.0, data set for INCL/ABLA hadronic models Updated data sets: – G4EMLOW-6.35, G4NDL-4.4 (compressed), G4NEUTRONXS-1.4, RadioactiveDecay-4.0, PhotonEvaporation-3.0 10 December 2013G.Cosmo - Geant4 release 10.0 highlights - kernel modules9

10. 10.0: more … Configuration (Cmake) Adapted to support MT configuration New export function for datasets. Added new '--datasets' argument to print out space separated dataset name, envvar name and path Deprecated old GNUmake tools Digits-Hits Added ability to merge scoring quantities in MT mode Examples – Redesigned examples (basic & extended) – Many examples migrated for demonstrating use of multi-threading 10 December 2013G.Cosmo - Geant4 release 10.0 highlights - kernel modules 10
