Abstract
We demonstrate a novel technique to measure the longitudinal profile of an operational hydrogen ion (H-) beam in a nonintrusive, real-time fashion. The measurement is based on the photoionization of the ion beam with a phase modulated laser comb – pico-second laser pulses with controllable temporal structure. The measurement technique has been applied to a 1-GeV, 1.4-MW H- beam at the Spallation Neutron Source (SNS) high energy beam transport (HEBT). A stroboscopic photograph of the H- beam micro bunch can be obtained by using a phase modulated laser comb. The entire measurement takes only 700 μs.
