- General code cleanup for removal of warnings.
|
||||
- cross_sections:
|
||||
o Included the high Q2 part of the cross-section into electro and
|
||||
photo nuclear reaction cross-sections, and into the equivalent
|
||||
photon production.
|
||||
o New class for calculating projectile fragment cross-sections in
|
||||
ion ion reactions. Implements Physical Review C61, 034607 (2000).
|
||||
based on EPAX Version 2, with the kind permission of the authors.
|
||||
- management:
|
||||
o Included recoil charge state treatement in HadronicProcess.
|
||||

|
||||
o Using quark-gluon string model now to simulate reactions with large
|
||||

|
||||
o Added protection for reactions at threshold.
|
||||
- models/coherent_elastic:
|
||||
o Improvement for coulomb effects.
|
||||
o Correction of array sizes; slightly extends the applicability.
|
||||
- models/high_energy:
|
||||
o Fix for a long standing problem in phi symmetry traced to the Cross
|
||||
method of G4HEVector.
|
||||
- models/leading_particle:
|
||||
o New package, steming from a partial re-implementation of the MARS
|
||||
code. Valid for energies below 5 Gev for proton/neutron/pi+-,
|
||||
K+-/gamma/anti_proton
|
||||
The code is intrinsically leading particle biased, hence applicable
|
||||
for radiation background simulations.
|
||||
Typical application of this would be in the ESA MOLASSIS application.
|
||||
- models/low_energy:
|
||||
o Correction for randomization of fermi motion (1 in 1000 effect).
|
||||
o Better treatement for anti-nucleons through accounting of
|
||||
annihilation energy.
|
||||
o Various cross-sections in the accounting of nucleons.
|
||||
o Improved pi-0 to charged pion rations used in low energy models.
|
||||
o Improved treatement of Lorentz transformation, getting rid of the
|
||||
1 in 100 phi=0 peak for nucleons.
|
||||
- models/neutron_hp:
|
||||
o Resolved a problem in the effective luminosity correction
|
||||
in the doppler broadening on the fly. Removes a bias in capture time
|
||||
on termal neutrons in hydrogen (was off by 10%).
|
||||
- models/radiative_decay:
|
||||
o Fixed problem with sort, leading to erroneous behavior.
|
||||
- models/generator/de_excitation:
|
||||
o Moving the catching of low energy gammas.
|
||||
o Adding a complete set of fresh evaporation code, that is more or
|
||||
less equivalent to the GEM evaporation models. It produces fragments
|
||||
up to Na25. Currently at beta level. G4Evaporation::SetGEMChannel()
|
||||
method should be used to activate this.
|
||||
- models/generator/high_energy:
|
||||
o Included direct strong resonance decay in case of scattering off
|
||||
hydrogen, hence removing this boundary use-case from the cascade
|
||||
interface specifications.
|
||||
- models/generator/management:
|
||||
o Added utility interface for nucleus and nuclear density functions,
|
||||
for the use of cascade codes.
|
||||
- models/generator/pre_equilibrium:
|
||||
o Fixed error in the low energy proton distributions
|
||||
o Improvements in the level density.
|
||||
o Bug fixed in angular distributions (theta).
|
||||
o Small bug fixed in the equilibrium exciton number.
|
||||
o Migration to new pairing corrections.
|
||||
- models/generator/quark_gluon_string:
|
||||
o Design iteration to enable specialization of participants
|
||||
in string excitation.
|
||||
o Added gamma nuclear reactions by adding specialised participants for
|
||||
this; based on single nucleon participant model, and mesonic structure;
|
||||
assuming vector meson dominance in the reactions and splitting.
|
||||
- models/generator/util:
|
||||
o Added utility for the decay of strong resonances.
|
||||
o Added consts to enforce few design considerations.
|
||||
|
||||
o Magnetic Field:
|
||||
--------------
|
||||

||||
|
||||
1. Supported and Tested Platforms
|
||||
---------------------------------
|
||||
|
||||
o SUN Solaris 5.7, C++ 5.2 Patch 109508-03.
|
||||
o Linux, gcc 2.95.2, egcs-2.91.66 (egcs 1.1.2).
|
||||
This configuration was tested with the RedHat 6.1 and 7.2 distributions,
|
||||
versions of Geant4 have also been compiled successfully on other Linux
|
||||
distributions, like Debian or Suse.
|
||||
The default RedHat compiler gcc-2.96 ditributed in RedHat 7.X is NOT
|
||||
supported. It has been verified that it produces incorrect binaries,
|
||||
therefore is not reliable. See also note below.
|
||||
o Windows-2000 and CygWin Tools with: Visual C++ 6.0 Service Pack 5
|
||||
|
||||
Platforms configured but not tested and not supported:
|
||||
o DEC V4.0, cxx C++ V6.1-027 with/without ObjectSpace STL
|
||||
o HP 10.20, aCC C++ B3910B A.01.23 with/without ObjectSpace STL
|
||||
o SGI V6.5.5, CC 7.2.1 with ObjectSpace STL
|
||||
o AIX 4.3.2, xlC compiler with ObjectSpace STL
|
||||
o MacOS 10.1, gcc 2.92.2
|
||||
|
||||
2. AIDA and CLHEP
|
||||
-----------------
|
||||
|
||||
Geant4 4.1 requires the installation of CLHEP.
|
||||
|
||||
See <A href="http://wwwinfo.cern.ch/asd/lhc++/INSTALLATION/clhep.html">
|
||||
CLHEP</A>. Tests have been performed with CLHEP 1.7.5.0. However, first
|
||||
level porting has also been verified on CLHEP 1.8.0.0.
|
||||
|
||||
By default, the CLHEP installation scripts will activate ISO/ANSI C++ features
|
||||
if the compiler is capable. You need to explicitly disable CLHEP settings in
|
||||
case you wish non-ISO/ANSI setup on specific compilers.
|
||||
|
||||
Geant4 4.1 examples with histogramming cowork with AIDA 2.2 implementations.
|
||||
These include:
|
||||
- ANAPHE 4.0.4 and components included therein:
|
||||
Objectivity 6.1.3
|
||||
HepODBMS 0.3.3.1
|
||||
CLHEP 1.7.5.0
|
||||
(see: <A href="http://cern.ch/anaphe">ANAPHE</A>)
|
||||
- JAS 2.2.5
|
||||
(see: <A href="http://jas.freehep.org">JAS</A>)
|
||||
- Open Scientist v8
|
||||
(see: <A href="http://www.lal.in2p3.fr/OpenScientist/v8/welcome.html">Open Scientist</A>)
|
||||
|
||||
AIDA headers can be downloaded from:
|
||||
<A href="http://aida.freehep.org">AIDA</A>
|
||||
|
||||
|
||||
3. The Standard Template Library
|
||||
--------------------------------
|
||||
|
||||
Native versions of STL have been tested on the following platforms:
|
||||
|
||||
Windows/2000, Linux, and SUN.
|
||||
|
||||
NOTES:
|
||||
|
||||
- Platform specific setup:
|
||||
o SUN: Native STL is required for ISO/ANSI setup.
|
||||
o Linux: Native STL is required (non ISO/ANSI setup for egcs compiler only).
|
||||
o W2000: Native STL and ISO/ANSI setup required (VC++ 6.0).
|
||||
|
||||
|
||||
4. Persistency
|
||||
--------------
|
||||
|
||||
See release notes for Geant4 4.0.
|
||||
|
||||
|
||||
5. Compiler Specific Problems
|
||||
-----------------------------
|
||||
|
||||
o Linux Red Hat 7.X, gcc-2.96.
|
||||
|
||||
- The default compiler distributed by Red Hat since release 7.0 is
|
||||
NOT supported and not considered reliable for running a Geant4-based
|
||||
application. In more than one test case, binaries produced by gcc-2.96
|
||||
have shown incorrect behavior, either due to wrong order of
|
||||
initialisation of static data in memory or to bugs in the system
|
||||
iostream classes, problems which apparently have all been solved in
|
||||
more recent versions of the compiler (3.X series).
|
||||
For information, gcc-2.96 is a compiler that has never been
|
||||
officially released, nor supported by the GNU team itself and is not
|
||||
considered reliable by the authors (for more information, see also
|
||||
http://gcc.gnu.org/gcc-2.96.html).
|
||||
|
||||
|
||||
6. Known Run-Time Problems and Limitations
|
||||
------------------------------------------
|
||||
|
||||
For a complete list of outstanding run-time problems and to submit any
|
||||
problem you may find running this version of Geant4, please refer to the
|
||||
Geant4 Problem Reporting System, available on the Web at this address:
|
||||
|
||||
http://wwwinfo.cern.ch/asd/cgi-bin/geant4/problemreport
|
||||
|
||||
|
||||
7. Compilation Warnings
|
||||
-----------------------
|
||||
|
||||
There are compilation warnings on some platforms. We do not believe
|
||||
that any will lead to incorrect run-time behaviour, but we are working
|
||||
on reducing them.
|
||||
|
||||
|
||||
8. Known Run-Time Warnings
|
||||
--------------------------
|
||||
|
||||
The following messages can be written to error output while tracking.
|
||||
We believe none give rise to incorrect behaviour.
|
||||
|
||||
o G4PropagateInField: Warning: Particle is looping
|
||||
- tracking in field will be stopped.
|
||||
It has performed 10000 steps in Field while a maximum of 10000
|
||||
are allowed.
