SPECTROMETER DETECTOR FOR QUANTITATIVE POTENTIAL MEASUREMENT

摘要

The spectrometer detector arrangement according to the invention consists essentially of an electrostatic opposing field spectrometer (SP) and a semiconductor detector (DT) arranged directly above the spectrometer (SP), concentrically with respect to the beam axis (OA). The annular semiconductor detector (DT) is constructed in segments, the regions (ES) which are sensitive to particles being arranged symmetrically with respect to the beam axis (OA) and preferably being designed as a metal-semiconductor junction or as a p-n junction.
