Description
Summary:A relatively simple, position-sensitive particle detection system is described. The system is used in the momentum analyzer of a two-stage mass spectrometer system. The detector consists of two channelplates and a multi-anode collector. The position information is preamplified by two charge amplifiers and processed by a special purpose microprocessor system. The entire combination of detector and two-stage mass spectrometer has been tested by the measurement of the momentum distribution of the ionic fragments of the photodissociation of H 2 + into H + and H. The results of these measurements over a photon wavelength between 570 nm and 622.5 nm are presented and compared to the well-established theory of the photodissociation of H 2 +.
