Production and Dosimetric Evaluation of an Ion Beam at the Aurora Facility

Abstract

A large fluence of ions (protons) was produced by using a single arm of the Aurora in a reversed polarity from its typical operation (4-5 MeV,8k Joules). A spatially and temporally homogeneous proton current density was produced over more than 300 cm2 . Electrons emitted from a tubular cathode impinged on a 2-mil polyethylene foil producing the protons, whose depth-dose deposition could be controlled by the A-K spacing. A variety of measurement techniques; (1) electromagnetic, (2) radiachromic-depth-dose, (3) diamond PCD, (4) calorimetric, and (5) proton time-of-flight were used to verify these results. These techniques are described and the results discussed and compared.
