A position-sensitive time-of-flight analyser for study of molecular photofragmentation

The basic features of a simple radial position-sensitive detector design, construction and performance, are described in detail in this paper. The electronics and method used to correlate the position information from the spectrum recorded by the detector are presented. Monte Carlo simulations of the performance of the detector embedded in a time of flight analyser show that such an instrument enables kinetic energy and angular distribution measurements and triple coincidence studies of photofragmentation of simple molecules.
