Description

A very low-pressure magnetically-focused electron bombardment ion source is described which produces substantial quantities of ions in highly excited metastable states. Using the laser--fluorescence technique, we have measured a 2s3S1 metastable content of 0.6%--2.3% in a 0.4 μA, 5 keV beam of 7Li+. The source design can be applied to essentially any ionic species and offers the additional advantage of relatively low energy spread
