Nucleon-ion and ion-ion collisions at non relativistic bombarding energies can be described by means of Monte Carlo approaches, such as those based on the Quantum Molecular Dynamics (QMD) model. We have developed a QMD code, to simulate the fast stage of heavy-ion reactions, and we have coupled it to the de-excitation module available in the FLUKA Monte Carlo transport and interaction code. The...
Heavy-ion collisions can be simulated by means of comprehensive approaches, to include the many different reaction mechanisms which may contribute. QMD models and their relativistic extensions are examples of these approaches based on Monte Carlo techniques. In this paper are shown some results obtained by coupling a new QMD code, which describes the fast stage of ion-ion collisions, to the eva...
This paper provides an overview of the problems, challenges, and advanced simulation techniques used to study plan complex interventions in radiation areas at CERNs Large Hadron Collider its future upgrade High-Luminosity Collider. The operational protection aspects are supported by state art simulations means FLUKA Monte Carlo code estimates conducted via other tools such as ActiWiz SESAME, wi...
Nuclear effects in neutrino-nucleus reactions simulated by means of the NUX+FLUKA Monte Carlo generator are compared with the theoretical predictions of the Marteau model. Pion absorption in NUX+FLUKA and non-pionic ∆ decays in the Marteau model differ by about 30%. The fraction of pions produced due to the re-interactions after primary quasi-elastic vertex is in the NUX+FLUKA scheme much highe...
background: palladium-103 (103pd) is a brachytherapy source for cancer treatment. the monte carlo codes are usually applied for dose distribution and effect of shieldings. monte carlo calculation of dose distribution in water phantom due to a med3633 103pd source is presented in this work. materials and methods: the dose distribution around the 103pd model med3633 located in the center of 30×30...
The FLUKA Monte Carlo transport code is widely used for fundamental research, radioprotection and dosimetry, hybrid nuclear energy system and cosmic ray calculations. The validity of its physical models has been benchmarked against a variety of experimental data over a wide range of energies, ranging from accelerator data to cosmic ray showers in the earth atmosphere. The code is presently unde...
The Monte Carlo program FLUKA was used to calculate the number of muons reaching detection level in events initiated by primary cosmic gamma ray interactions in the atmosphere. The calculation was motivated by the desire to gauge the sensitivity of arrays like that of Project GRAND to primary gamma cosmic rays while measuring single muons at detection level. Because direct gamma pair production...
This paper is a continuation of the preliminary dosimetric evaluation of source terms at PW laser systems [1] the proton case. The main acceleration mechanisms and the associated characteristics of the accelerated proton beams were briefly presented. FLUKA and GEANT4 Monte Carlo transport codes were used to compute absorbed doses due to three proton beams of well defined energy and spatial dist...
The planned new Heavy Ion Synchrotron SIS 100/300 for the FAIR Project will consist of two separate tunnels. In addition to the tunnel where the beam lines itself will be situated, there will be an additional tunnel, for maintenance and supply purposes. This maintenance tunnel is desired to be accessible for technical personnel also during beam operation. Therefore, from the radiation safety po...
