Lithium Hydride Bremsstrahlung Beam ``Hardener''

Abstract
The attenuation of the low energy component (below 50 Mev) of the bremsstrahlung beam of a high energy electron accelerator by several low‐Z absorbers is studied. In particular, the advantages and construction of a lithium hydride absorber are described. The experimentally measured attenuation is compared with that calculated from a single interaction model, and several further suggestions are offered.
