Bremsstrahlung radiation power in non-Maxwellian plasmas
Nuclear FusionIn plasmas, bremsstrahlung includes electron–ion (e–i) bremsstrahlung and electron–electron (e–e) bremsstrahlung. Bremsstrahlung radiation power loss is one of the most significant losses in fusion plasmas, which is more pronounced in higher temperature ...

On multiphoton bremsstrahlung [PDF]
Physics Letters A, 1999 Kinetic equations for the process of multiphoton bremsstrahlung of electron in a matter have been used to derive the equations for the moments of distributions of electrons over the number of emitted photons and over the energy loss. The equations for the moments have been solved in continuous slowing down approximation.

Monte carlo assessment of advanced shielding materials for space-efficient radiotherapy vault design. [PDF]
J Appl Clin Med PhysAbstract Background Conventional radiotherapy vault shielding typically employs 2 to 3 meters of ordinary concrete, consistent with NCRP Report 151 reference data. While NCRP 151 specifies dose‐based design goals rather than mandating particular materials, the practical default of concrete results in vault footprints of 150 to 200 m2 per linac, which ...

MCNP simulation for gamma-ray buildup factors of shielding material
He jishu, 2021 BackgroundIn the shielding design of γ-ray, it is very important to select the appropriate buildup factor for the shielding effect. As far as the current data are concerned, when designing the shielding material, the effect of bremsstrahlung is ...

Bremsstrahlung conversion efficiency and gamma - neutron generation from polypropylene, aluminum, iron, and lead bombarded by 10 MeV electrons [PDF]
Nuclear Technology and Radiation Protection, 2020 An electron beam from the UELR-10-15S2 accelerator (average energy of 9.92 ± 0.48 MeV) was applied to irradiate food and medical items at the Research and Development Center for Radiation Technology, Vietnam Atomic Energy Institute, Vietnam. The

Physical Review D, 2019 Simple analytic formulas are considered for the energy radiated in low frequency bremsstrahlung from fully ionized gases. A formula that has been frequently cited over many years turns out to have only a limited range of validity, more narrow than for a formula derived using the Born approximation.
