A compact time-of-flight energy analyzer of high resolution
Abstract
The design and calibration of a time-of-flight proton energy analyzer in the energy range 10 to 100 keV is described. 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 to 30 cm) permit a compact design with energy resolution of 2%. The analyzer may be used in an environment with a high background of neutrons and gamma radiation. The sensitivity of this background is strongly reduced by the doubly coincident detection of the particles. The small overall dimensions of the analyzer are important whenever the background level is so high that a screening cannot be completely avoided.
