Diagnostics of pulsed ion beams and ablation plumes exhausted from targets irradiated by ion beams

Three kinds of experimental results are shown here. With a pinhole camera, we tried to measure the micro-divergence angle of ion beams. A CCD element was then tested as an end plate of a Thomson parabola analyzer. This element was directly irradiated by ion beams to produce electric signals associated with the beams. We also built a cryogenic target which was cooled by liquid nitrogen, and the ice-covered target was irradiated by proton beams to measure the concerned ablation processes.
