Mp. Stockli et al., IMPROVEMENTS ON THE KSU-CRYEBIS - A FACILITY FOR LOW-ENERGY, HIGHLY-CHARGED IONS, Review of scientific instruments, 67(3), 1996, pp. 1162-1164
The KSU-CRYEBIS, a cryogenic electron beam ion source, delivers ions o
ver a wide range of ion energy per charge, ion mass, and charge state
for atomic physics experiments. Lower charge states yield time-average
d currents in the nA range, whereas the highest charge states, such as
Ar18+ Fe24+, Kr34+, and Xe47+, yield time-averaged currents in the pA
range. The number of available species and isotopes has been substant
ially increased, and include metalorganics to produce stable, high-yie
ld beams of metal ions. The high-voltage platform control system and t
he ion optics have been improved and allow for acceleration of the ion
s to 160 kV/q as well as for deceleration to a fraction of 1 kV/q. The
diagnostics of the facility are continuously being upgraded. (C) 1996
