Sl. Bogomolov et al., PULSED EMISSION OF IONS FROM THE PIG SOURCE WITH AN ADDITIONAL ANODE, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 126(1-4), 1997, pp. 63-65
A method for the production of short ion pulses from the source with a
n additional anode is proposed. For the production of short ion curren
t pulses the negative bias is applied to an additional anode to suppre
ss the extracted current and then, at a desirable moment of the discha
rge pulse, a short positive pulse is applied to provide a pulse of ext
racted current. The possibility of selective ion emission by means of
the additional anode potential oscillation with frequency, proportiona
l to the ion cyclotron frequency of the selected sort of ions, is cons
idered.
