Dear FLUKA users,
It is our pleasure to announce that a new minor release of the FLUKA code, FLUKA 4-2.2, has been issued and can be downloaded from here.
See the release notes at the bottom of this message for a detailed account of all novelties. Many thanks to all users who reported the issues here addressed.
With our kindest regards,
The FLUKA developer team at CERN and collaborating institutes
=== Fluka-4.2.2 ===
PHYSICS IMPROVEMENTS:
- Shell and pairing effects adjustment in the course of the IntraNuclear Cascade (already implemented since FLUKA 4-2.0).
- A typo in the RELEASE-NOTES for FLUKA 4-2.0 has been fixed: the proton reaction cross section refinement for {63,65}Co should have read {63,65}Cu.
BUG FIXES:
- Fixed the unexpected behavior reported in this forum post due to a spurious setting in the pre-equilibrium stage of FLUKA's hadron-nucleus inelastic interaction module.
- Fixed a rare crash reported in this forum post due to a bookkeeping error for biased low-energy nuclear projectiles with A>2 on 2H in inverse kinematics.
- Fixed the gamma double counting reported in this forum post due to the attribution of decay products of 109*Ag to 109Cd too.
- Fixed a bug which truncated multiple Auger-electron emission from radionuclides to a single one.
- The offset of a magnetic field prescribed in the input card MGNCREAT now applies not only to field maps, but also to analytical magnetic fields.
- A missing transformation matrix has been introduced to correctly apply the azimuthal angle prescribed in the MGCNREAT card.
- Whereas in previous versions the MGNDATA and MGNFIELD cards had to appear after the MGNCREATE card to properly work, now they are position-independent.
- A meaningful abort message is now written to the output file if no field data are given in case a 2D/3D field map is requested.
- Fixed an incorrect region indexing in the magnetic field acquisition in case lattice indices started from a value different from 1.
- Increased upper energy limit for stopping power tabulations so as to accommodate high-energy protons generated in relativistic ion collisions.
- The source.f user routine now initializes the age variable (AGESTK) also in the case of radioactive-isotope decay, fixing the issue reported in this forum post.
