Test on electron forward scattering from foils at 13-20 MeV

Main authors:B. Faddegon, University of California, San Francisco, US.

Short description: A mono-energetic electron pencil beam (normal incidence) of either 13 MeV or 20 MeV, and Gaussian circular spot of 0.1 cm FWHM travels through an exit window, a scattering foil made of Al, C, Ti or Be with different thickness, a monitor chamber, and 2 Mylar bags that limit a slab made of Helium.
