Development and diagnostics of revised ion beam analyzer, ion or laser produced plasmas and X-ray pre-ionizer for gas lasers

A CCD element was 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. With a pin-hole camera, we also tried to measure the divergence angle of ion beams. Coated thin layers of ion source materials on a quartz plate were back-lighted by an e-beam pumped KrF laser, and the produced plasmas were observed to supply advanced source plasmas for pulsed ion diodes. We 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. Fundamental characteristics of an X-ray source with wire-initiated discharge plasmas for pre-ionization of gas mixtures of our former discharge-pumped KrF laser in place of UV pre-ionization were also investigated.
