M. Olivo et al., STUDIES ON THE POSITIVE HYDROGEN-ION PRODUCTION FROM A SMALL MULTICUSP SOURCE, Review of scientific instruments, 65(4), 1994, pp. 1395-1397
An rf driven ion source has been developed and tested at LBL for posit
ive hydrogen ion production. Studies of this new source on ion species
and current densities for a dc arc discharge are made in the 60-kV PS
I ion source test stand and the results compared with those obtained u
sing the rf discharge. This source, using both discharge modes, will b
e installed in the PSI Cockcroft-Walton preinjector to increase the 87
0-keV dc proton beam intensity from the present 8-10 mA operation to a
bout 25 mA.
