Dear FLUKA users,
Fluka2023.3.3, a minor respin of Fluka2023.3, is now available on the
official FLUKA web site (www.fluka.org).
This respin fixes a few issues, and introduces two extra features:
The features:
- when using Runge-Kutta for particle tracking in magnetic field, the
rounding on the momentum conservation is now dealt with in a better
way, allowing to keep the overall momentum conservation at 1.E-15
level even with steps with thousands of sub-steps. This new approach is
activated automatically when Runge-Kutta tracking is requested in
magnetic field only. Thanks to N.Mazziotta for pointing to the need
of a better approach;
- when using pulse-height estimators (DETECT option), the user can now
access the scored quantity at the end of each event (eg inorder to
modify it applying a resolution). This can be accomplished through the
user routine detscw.f (the template is available in the usermvax
directory), which can be activated setting WHAT(4)=1 in the USERWEIG card.
The issues now fixed:
- an issue causing spurious crashes when performing (anti)neutrino
interactions, thanks to P. Sala for reporting it;
- a problem resulting in incorrect (too high) interaction threshold for
heavy ions in reverse kinematics. For heavy ions in the rQMD energy
range, when the projectile was much heavier than the target, the
interaction threshold was erroneously set too high resulting in
rejecting most of the interactions. Thanks do Dr A. Senger for reporting
it;
- a rare spurious crash due to the Silicon damage function getting
confused for neutrons below 1.E-14 GeV, which are now possible with
pointwise cross sections, thanks to R. Dos Santos Augusto for reporting it;
- a typo in the Ambient Dose conversion coefficient for pi+ at 200 GeV;
- a few rare random number non reproducibility's;
- an error in the pdf manual wrongly reporting how to get neutron
point-wise spectra with USRBDX/USRTRACK/USRCOLL. The Ascii manual
was already correct. Thanks to K.Batkov for reporting it.
At the same time, some clean-up of the code has been also performed as
usual.
All users are urged to update to this respin. This is particularly
important because the fixes will change the random number sequence also
for problems not affected by the issues listed above. As usual, assistance
will be provided only for the latest release/respin.
