COMPOSITION OF NOBLE GAS ION BEAMS PRODUCED WITH A DUOPLASMATRON,
Abstract
Beams of noble gas ions produced with a duoplasmatron ion source were magnetically analyzed while the gas pressure in the source was varied. At high pressure the beam consisted primarily of singly-charged ions. With decreasing pressure the yield of multiply-ionized ions increased and was finally limited by the rising arc voltage which caused overheating of the anode. No measurable amount of He(2+) or Ne(2+) was detected. In the other gases the following maximum yields were measured for the more highly ionized species: 63% A(2+), 54% Kr(2+), 16% Kr(3+), 24% Xe(2+), and 1.2% Xe(3+). Traces of molecular ions were detected in all the noble gases studied. (Author)
