RE: [fluka-discuss]: New Fluka major eelease, fluka2023.3.0

Dear alfredo.ferrari_at_mi.infn.it <alfredo.ferrari_at_mi.infn.it>;

I haven’t accesses to

fluka2023.3-linux-gfor64bit-13.2-glibc2.37-AA.tar.gz gfortran 13.2,

glibc2.37

on the official FLUKA web site (www.fluka.org).

What’s about this?

Thanks all Fluka team for the new release fluka-2023.3-0.

Dear FLUKA users,

Fluka2023.3.0, a major iteration of the 4th generation of the FLUKA code, is

now available on the official FLUKA web site (www.fluka.org).

This release represents a big step forward for FLUKA, it contains several

important new features and changes.

In the following a short list of the main new features:

- Photonuclear interactions: both cross sections and models are

  completely new above ~100 MeV: this is a major improvement which gets

  rid of many limitations and inaccuracies of the the previous

  implementation (see the release notes for more details);

- Photon cross section: upgraded from EPDL97 to EPICS2017;

- Photon cross sections and bremsstrahlung cross sections are now extended up

  to 1.E21 eV;

- GDR photonuclear cross sections have been updated for a few isotopes,

  in particular Lead ones;

- Ortho-Positronium three-gamma annihilation is now included, including

  the 3-body matrix-element for the decay;

- The hadronisation model of the high energy generator has been fully

reworked

  in order to better account for experimental data which somewhat contradict

  widely accepted assumptions about string fragmentation;

- All hadron-nucleus cross sections are new and extended up to 10^20 eV,

  and all of them are now consistently calculated with Peanut: they have

  been validated up to the highest cosmic ray data;

- Coherent elastic scattering of neutrons between 20 and 40 MeV is now

  treated using ad-hoc Legendre expansions;

- Updated galactic cosmic ray spectra, now based on AMS02 data (thanks

  to Nicola Mazziotta and Pedro de la Torre Luque) are now available:

  they can be activated by new option in SPECSOUR : sdum = GCR-AMS;

- Built-in source routines for neutron spectra from Am-Be, Am-B, 252-Cf

  sources are now available (see the BEAM card);

- Internal conversion decays (IC) are now modeled as such and no longer

  as (wrongly) gamma emission, including the explicit transport of the

  excited nuclei to the decay point;

- The charged particle stopping power in water is now defined in agreement

  with the ICRU90 recommendations. In particular, but not only, the water

  average ionization potential is now set to I=78 eV;

- The sampling of the example solar flare spectra has been definitively

  corrected;

- The default DPMJET is now the newest one, 3.19.3.x, the previous version

  is no longer distributed;

- By default intranuclear cascade reinteractions in Dpmjet are now treated

  by the FLUKA hadronic models;

- The sets of fluence-to-dose conversion coefficients from ICRP116 are now

  available, in particular ambient dose has been added;

- A new interface to Ultra High Energy Cosmic Ray generators is now

  available: at present it supports interfacing to EPOS and Sibyll. For

  a rationale of this interface, and on how to use it, please refer to

  the release notes;

- Dose averaged LET maps are now implemented on-line (generalized particle

  DOSAVLET);

- Corresponding neutron group-wise cross sections no longer needed if

  point-wise one are requested for a given material;

- The source code has been deeply reorganised. Among others, the old high

  energy interaction model (eventv/eventvmvax) has been removed, since it

  is no longer used by any of the interaction routines.

At the same time a new bug fixing version of flair, python3 version only#,

is also available on the web site.  Those new python3 compatible files

are called flair...2.3-0dpy3..., see www.fluka.org/flair/download.html,

let us know if there are problems.

Due to the amount of changes/additions, and despite the extensive testing

carried out by the FLUKA collaboration members, rare bugs cannot be

excluded. If you experience a crash, or you feel something is incorrect

when running fluka2023.3, please report the issue at fluka-discuss_at_fluka.org.

All users are urged to update to this release. As usual, assistance

will be provided only for the latest release/respin.

     The FLUKA developers

# The python2 version of Flair is frozen and no effort will be made to

 fix still existing problems. If possible, migrate to the python3 version
