Abstract
An assembly for a charged particle detection unit is described. The assembly comprises a scintillator disc, a partially coated light guide a thin metal tube for allowing the primary charged particle beam to pass through and a photomultiplier tube (PMT). The shape of scintillator disc and light guide are redesigned to improved the light signal transmission thereafter enhance the light collection efficiency. A light guide with a conicoidal surface over an embedded scintillator improved the light collection efficiency of 34% over a conventional design.
