In 2014 a new vertical flight path was installed at the neutron time-of-flight facility, n TOF, at CERN. The beam line optimization of this second experimental area (EAR2) was performed by FLUKA simulations with a detailed model of the facility, including the spallation target, neutron beam line, magnet, collimators and beam dump. The beam profile as well as neutron and gamma fluxes were calcul...

Progress of the shielding calculation of the Super-FRS is reported here. At least as important as the shielding of the target area is the determination of the shielding in the region of the first dipoles as the part of the primary beam that will not interact in the target will be stopped here. The Monte-Carlo-method with FLUKA [1] used for the shielding assessment here has already been describe...

Introduction: Nowadays, the use of heavy ion beams in cancer therapy have been developed worldwide.   Materials and Methods: It requires accurate understanding of the complex processes of ion interaction with matter, as it is the calculation the relative dose & range of these ions in matter. In the present study we used FLUKA as a numerical Monte Carlo simula...

Background: In radiation therapy, water is the phantom material of choice, both for reference and for relative dosimetry measurements. Solid phantoms, however, are more useful for routine measurements because they tend to be more robust and easier to set up than water phantoms. Materials and Methods: FLUKA input data cards have been arranged in sequential order. A simple cylindrical geometry wi...

The production of muons in atmospheric showers initiated by gamma rays with energies below 10 TeV is calculated using the Monte Carlo code FLUKA. The simulations as well as various general properties of the muons reaching sea level and of their ancestors in the cascade are discussed.

FLUKA is a general purpose Monte Carlo code able to describe the transport and interaction of any particle nucleus type in complex geometries over an energy range extending from thermal neutrons ultrarelativistic hadron collisions. It has many different applications accelerator design, detector studies, dosimetry, radiation protection, medical physics, space research. In 2019, CERN INFN, as cop...

The neutron background at the underground laboratory at Boulby-a site for several dark matter experiments-is discussed. Special emphasis is put on the neutron background produced by cosmic-ray muons. The most recent versions of the muon propagation code MUSIC, and particle transport code FLUKA are used to evaluate muon and neutron fluxes. The results of simulations are compared with experimenta...
