A time and position sensitive ion detector has been developed for a stigmatic imaging mass spectrometer. To realize a high spacial- and time-resolved detector which detects multiple ion signals with a short measurement time, we have applied a Silicon-On-Insulator (SOI) CMOS process which realizes fast response. By measuring ion flight time at each pixel independently, a multi hit detection can be achieved, which will make a stigmatic imaging mass spectrometer more useful analytical technique.
