Longitudinal charge distribution measurement of nonrelativistic ion beams using coherent transition radiation

Abstract

Longitudinal charge profile measurements or bunch shape measurements are a challenge for temporally short nonrelativistic bunches. The field profile has a larger longitudinal extent compared to the charge profile for such beams. This affects the ability of field sensing devices such as phase pickups or wall current monitors to measure charge distribution. Here we evaluate the feasibility for usage of coherent transition [V. L. Ginzburg and V. N. Tsytovich, Transition Radiation and Transition Scattering (Adam Hilger, New York, 1990)] and diffraction radiation from nonrelativistic beams for single shot bunch shape measurements in the time domain.
