Description

The 4-Jaw Slit System can be used for analyzing as well as forming the size and shape of a charged particle beam. It consists of four plates which can be moved individually from an out-of-beam position into the beam. The position of the slits is adjustable with sub-millimeter precision.

Optionally, the charged particle beam current can be measured on the slits which gives additional information on the beam size and position and can be helpful for charged particle beam guiding. The technical specifications and operation parameters of the slit system can be tailored according to customer demands.
