In this paper, a current profile monitor for the scanning electron beam from the accelerator is described, which utilizes the fact that the electrons scattered through large angles by the exit window of the scanner show a profile similar to that of the main beam at the irradiation site.Abstract:
A current profile monitor for the scanning electron beam from the accelerator is described. It utilizes the fact that the electrons scattered through large angles by the exit window of the scanner show a profile similar to that of the main beam at the irradiation site. The scattered electrons are collected by small probes arranged in a linear array parallel to the scanning direction, and the beam profile in this direction is displayed by a storage oscilloscope or an X‐Y recorder. This device has been used for electrons of energies 4–16 MeV from a linear accelerator and proved to be useful for continual monitoring with negligible disturbance to the irradiation in progress.read more

Design considerations for a beam scanner at the university of Manitoba Cyclotron facility
Christopher Haddock,F. Konopasek +1 more
TL;DR: In this article, the authors describe the development of a beam scanner for the University of Manitoba Cyclotron, which gives an output on an oscilloscope of the beam profile, a "cross sectional" view of the intensity of the charged particle beam and its position.

Measurement of multiple scattering of 15.7-mev electrons
TL;DR: In this article, the angular distribution of electrons scattered by thin Be and Au foils has been measured for angles where the multiple scattering is important, and the 1e widths of the distributions obtained with 18.66 and 37.28 mg/cm2 are 2.58° and 3.76°, respectively.
