Beam shaping assembly optimization of Linac based BNCT and in-phantom depth dose distribution analysis of brain tumors for verification of a beam model

The investigation of physical conditions of boron uptake region in proton boron fusion therapy (PBFT)

“…16,17 The phantom was then partitioned into 100 slabs with 0.1 cm thickness (6W × 6H × 0.1D cm 3 ) as the unit volume for measuring the proton dose. 18 We assumed the proton beam was extracted from a point source and the distance from the point source to the phantom surface was 10 cm. We used four proton energies (60, 70, 80, and 90 MeV) to mainly test the effectiveness of the PBFT in low proton energy conditions.…”

“…Tracers such as 18 F-FDG have been commonly used to help in diagnosing cancers and improving radiation therapy. 1,2 BNCT also can selectivity target tumor region tagged using the tracers with boronate compounds (i.e.…”

Monte Carlo simulation of moderator and reflector in coal analyzer based on a D -T neutron generator

“…A layer of neutron reflector is added in that space to improve the ratio of thermal to fast neutron and the total neutron flux. The commonly used neutron reflector materials are Pb, Bi, W, Be, Nb, V, and graphite (Uhlá00 R, 2014;Durisi E, 2007;Gohar Y, 2000;Rahmani F, 2011). Because of the space constraints in the system, the maximum thickness of the reflector is 30 cm.…”

Design of photon converter and photoneutron target for High power electron accelerator based BNCT

“…After neutron source design, in order to show the performance of the designed target for BNCT application, produced neutron in the neutron target including PC and PNT has been moderated using typical Beam Shaping Assembly (BSA) which consists of 10 cm Iron, 20 cm MgF 2 , 20 cm AlF 3 as the moderators, 1.5 cm LiF as the neutron shield, 5 cm lead for gamma shield and Ni as a collimator (Kasesaz et al, 2013;Rahmani and Shahriari, 2011;Torabi et al, 2014).…”
