Detectors for Position and Energy Measurement

Abstract

As the primary ionization in semiconductors is proportional to the energy loss of the incident radiation or particle, most semiconductor detectors will provide the possibility of energy measurement if the readout electronics measures the signal charge.¹⁹ Position sensitivity may be obtained by creating a situation in which the signal charge is split amongst more than one readout electrode with the ratio of charges depending on the position. Alternatively, the detector may be segmented in many small subdetectors that are read out separately.
