Microshutters for space physics time of flight applications
Paper i proceeding, 2010
In present time-of-flight (TOF) mass and energy spectrometers in experimental space plasma
physics applications, the resolution is limited by the fact that the particle to be measured loses part of its energy
in the generation of the start pulse. To improve the resolution, a fast micromechanical shutter system to
generate the start signal has been developed. The microshutter is included in the PRIMA (PRIsma Mass
Analyzer) ion detector on-board the Swedish PRISMA mission, which will be launched into low Earth orbit on
June 15, 2010.
