Abstract

Short ion pulses (∼100 ns FWHM) have been produced from an In liquid metal ion source (LMIS) of the needle type by superimposing short voltage pulses (∼500 ns) onto a subcritical extraction field. Extractor-pulsed LMIS are thought to be useful as primary ion sources in time-of-flight (TOF) mass spectrometers, particularly for space applications, where extended charge life time and reduced power consumption are of great importance.
