Potential Measurements of an Intense Pulsed Ion Beam

Abstract

Potential measurements have been made on an intense proton beam with a capacitive voltage monitor. Beam potential as a function of position and diode voltage exhibit characteristics which can be explained by 1-D theory and simulation. The capacitive monitor causes a minimal pertibation of the beam potential. Discrepancies with theory can be explained by the violation of the cold electron source assumption. The potential measurement have been corroborated with ion current density measurements made with a biased charge collector. The data indicates a large thermal spread for the comoving electron velocity distribution. (jhd)
