Advanced studies of medium-mass ion sources-2: Production and measurement of (l)pure carbon plasmas as candidate source plasmas, and (2) silicon and carbon beams 1

Two kinds of source developments were tried for the generation of pulsed medium-mass ion beams. The first was the pure anode plasma formation with the fs-laser light irradiation of a (conductive) graphite target. The other was beam production from a dielectric anode, which was covered with a diamond like carbon film or silicon layer. The preliminary results were disclosed here.
