Model HWIG-250 Ion Gun and Power Supply

HWIG-250 Ion Gun HWIGPS-4 (Floating) Power Supply HWIG-250F Ion Gun Shown With Exit Aperture

Our Model HWIG-250 Ion Gun is a complete ion gun assembly. This is supplied with a Cesium (or ion other type) source pellet already installed and is designed to be mounted within a vacuum chamber or instrument. The gun is capable of producing a 10 KeV ion beam of over 1 microamp (Cs) focused to a spot size of less than 1 mm² at a distance of 2.5 cm from the exit aperture. Model HWIG-250F is designed to mount to a 23/4" CFF Model HWIG-250F can mount with optional 102654 X-Y adapter kit Other Ion Types can be used if used with optional #101504 adapter Spare Cesium sources are #101141 Floating (PS-4) or non floating (PS-5) 15KV power supplies available HWIG-250F, above left, and HWIG-250, above right HWIG-250F Ion Gun Shown Without Exit Aperture/ Shield
