This cesiated surface results in a high negative secondary ion yield for those elements with a favorable electron affinity.

\nThe HVEE Model 133 cesium ion gun is especially designed for attachment to existing ion microprobes and ion microscopes. The Model 133 cesium ion gun can be rapidly interchanged with a Duoplasmatron ion source to provide the optimum in positive and negative ion yields with minimum downtime.<\/p>\n
\nCesium is controllably volatilized from a heated reservoir to feed a tungsten frit, which is heated up to 1100 oC. The cesium diffuses through the frit and is thermally ionized with almost 100% efficiency. The Cs+ ions are then accelerated and focused by the same ion optics as for a Duoplasmatron ion source.
\nThe Model 133 cesium ion gun is designed for routine, reliable operation. With proper care and attention, a cesium charge will last several hundred hours. The reservoir\/frit assembly is housed in a stainless steel chamber, which has a flange compatible with most ion probes.<\/p>\n
