The IOG 25AU is a high performance Liquid Metal Ion Gun
system designed to provide a range of gold and gold cluster ion
beams for SIMS applications. It offers a wide current range with
fine probe capability and d.c. or pulsed operation.
The IOG 25AU delivers a focused beam with
beam energy of up to 25 keV. The gun is fitted with a gold-germanium
alloy liquid metal ion source. A Wien filter allows selection of primary
ion species suitable for imaging with high spatial resolution or for
high mass range analysis.
