A novel trochoidal analyzer for the Belfast EBIT

Abstract

Presently, Queens University Belfast is constructing a unique permanent magnet EBIT which grants unparalleled access to the photons from the trap region. However measurements of ions would still require their transfer through the collector to other measurement areas. To allow more representative sampling, a new in situ analyzer is proposed to be situated immediately at the collector end of the trap region. This analyzer may detect ions by expanding the radius of their cyclotron motion using electric fields until the ions strike Microsphere Plates (MSPs). It may also be possible by using trochoidal motion to detect product electrons. This is important as these have never been detected before in an EBIT. The preliminary design is described in this paper. (c) 2005 Elsevier B.V. All rights reserved.
