Characterization of bremsstrahlung radiations for 6 to 18 MeV electron beam from different Z elements: experimental and simulation approach

This chapter deals with the study of bremsstrahlung spectra for 6 to 18 MeV electron beam from different materials such as low to high Z elements as an e target. The simulation using FLUKA involves the neutron, electron, positron and bremsstrahlung fluence determination at various angles Moreover the thickness of . , e target has varied from thin to thick i.e from 0.1% to 150% of RCSDA. In addi...

Beam-size Effect in Bremsstrahlung *

The smallness of the transverse dimensions of the colliding beams leads to suppression of bremsstrahlung cross section. This beam-size effect was discovered and investigated at INP, Novosibirsk. Different mechanisms of radiation are discussed. Separation of coherent and incoherent radiation is analyzed in detail. For linear collider this suppression affects the whole spectrum. It is shown that ...

Intensity modulated radiation therapy (IMRT) technique for left breast cancer by different numbers of beam fields

Background: Intensity Modulated Radiotherapy (IMRT) can improve radiotherapy (RT) results by improving healthy tissue sparing. Additionally, IMRT provides more consistent dose deliveries and suppresses secondary tumor formation. RT is a principal treatment in breast cancer (BC). Aim: To evaluate the outcome of the Radiotherapy Plans (RTP) that use IMRT technique to left breast and other organs,...

Beam-target Interaction Experiments for Bremsstrahlung Converter Applications

The DARHT II accelerator uses a pulsed high current electron beam and Bremsstrahlung converter target to generate an intense x-ray source for radiography. For the past several years, we have been performing an investigation of the possible adverse effects of (1) backstreaming ion emission from the Bremsstrahlung converter target and (2) the interaction of the resultant plasma with the electron ...
