A DETECTOR FOR DETECTING PARTICLE RADIATION OF AN ENERGY IN THE RANGE OF 150 EV TO 300 KEV, AND A MATERIALS MAPPING APPARATUS WITH SUCH A DETECTOR.

摘要

Detector for detection of particle radiation, particularly particle radiation having an energy in the range of 150 eV to 300 keV, comprising at least one detector element, said detector element comprising a semiconductor detector material, at least a set of line-shaped electrodes conductively connected to at least one surface of said semiconductor detector material, each set comprising a plurality of line-shaped electrodes extending in parallel, and signal processor communicating with said line-shaped electrodes, wherein, in each set, said line-shaped electrodes are distributed with a strip pitch of less than 3 μm, and that the thickness of said semiconductor detector material is of less than three times the strip pitch of said line-shaped electrodes.
