Download latest FLUKA release

Message for Lightweight account holders: CERN changed the SSO authentication interface. When downloading FLUKA, CERN lightweight account holders first need to click on "Guest access" on the bottom right and then enter their email and password on the new page. In case access is denied, we kindly ask you to reset your CERN Lightweight password. See also: instructions for Lightweight account holders

User registration is mandatory for downloading FLUKA. Please read the licence conditions and follow these instructions. Registered users can download the packages below (login with your CERN Lightweight account or your regular CERN account).

Previous FLUKA user ids (so-called FUIDs) do not grant access to the FLUKA packages on this website, but a new registration is required.

Once your registration is complete and you received the final confirmation email, it might still take a couple of hours until the registration database is synchronized and you can download the files.

System requirements and installation instructions can be found here. It is recommended to consult this page if you are unsure which package to download.

Latest FLUKA version: 4-3.0, released on:
Release highlights:

PHYSICS IMPROVEMENTS:

  • A new point-wise treatment has been included for the interactions of low-energy neutrons (below 20 MeV), controlled by the new LOW-PWXS card. The download of at least one additional package is required, as detailed here.

  • The code is now aligned with DPMJET v19.3.2, fixing spurious features in
    kaon spectra from nucleus-nucleus collisions at energies of ~10 GeV/n.

  • Scoring of athermal-recombination-corrected displacements per atom (arc-DPA) has been added, requiring two new user-specified parameters, as detailed in the MAT-PROP card documentation. Generalized particle DPA-NRES (#245) has been deprecated and replaced by the Norgett-Robinson-Torrens DPA-NRT.

  • The emission of synchrotron radiation photons along charged particle steps, in vacuum regions subject to a magnetic field, has been implemented and is requested via the SYRASTEP card.

  • Mass distribution of 226Ra fission fragments was corrected, addressing this forum post

TECHNICAL IMPROVEMENTS:

  • The new DETGEB card allows the user to apply a Gaussian broadening to energy deposition spectra scored with the DETECT card.

  • The maximum number of regions of interest (ROI) in voxel geometries has been increased from 100 to 400.

  • In the source_newgen.f user routine, sampling from a spectrum file (energy, intensity) was added.

  • The code manual has been recast in restructured text format, providing the user with three consistent versions: text, pdf, and html. The latter is accessible at https://flukafiles.web.cern.ch/manual .

Several bugs were fixed (see release notes for a complete list).
