Fig. 10.3 Induced currents in infinite planar electrodes for localized and extended ionization
Fig. 10.4 Weighting field (potential) for strip electrode configuration
signal charge (integral of the induced current) is independent of the position of the
origin of ionization for most of the volume of the detector except near the readout
electrodes. This effect is used in detectors where only electrons are collected during
the integration time, such as Cadmium Zinc Telluride (CZT), and some gas and
noble liquid detectors. To illustrate this, histograms are shown in Figs. 10.4 and 10.5
for a strip and pixel illuminated by a beam of penetrating x-rays absorbed uniformly
through the detector.
