Electron beam radiation is a very important treatment modality in dermatologic radiotherapy. The physical characteristics of electron radiation are well suited for treatment of superficial lesions, since the depth of penetration of the radiation can be precisely controlled, with little exposure of deeper tissues. Additionally, compared with superficial

Characterization of electron beams for modulated electron beam radiotherapy
Proceedings of the 22nd Annual International Conference of the IEEE Engineering in Medicine and Biology Society (Cat. No.00CH37143), 2002A set of clinical electron beams have been characterized in anticipation of their use in modulated electron radiotherapy (MERT). Using the EGS4/BEAM and DOSXYZ simulation codes, a Monte Carlo model of a Varian Clinac 2100C was generated for electron beams of nominal energies of 6, 9, 12, 16, and 20 MeV. Dose calculations using the Monte Carlo generated

Change of Electron Temperature in an Electron Beam
Journal of Applied Physics, 1953The effect of electron encounters on the velocity distribution in an electron beam after passage through an accelerating grid is calculated by direct integration of the Boltzmann equation. It is found, with electron densities and velocities typical of traveling wave tubes and diodes, that the electron encounters have a negligible effect, that the ...
