A COMPACT TIME-OF-FLIGHT ENERGY ANALYSER OF HIGH RESOLUTION
In this paper the design and calibration of an energy analyser for protons in the energy range of 10-1000 keV is described. The energy analysis is based on a time of flight technique. Secondary electrons from a very thin carbon foil are used to detect a passing particle. The use of microchannel plates and the short flight path (15-30 cm) permit a compact design with nevertheless a good energy resolution of 2 %. The analyser may be used in an environment with a high background of neutrons and gamma radiation. The sensitivity to this background is strongly reduced, in particular by means of the doubly coincident detection of the particles. The small overall dimensions of the analyser are important whenever the background level is so high that a screening cannot be completely avoided.
