Depth sensing technique using time-to-peak of anode signal in CZT detectors

Extensive investigation showed that it is feasible to extend this technique to Strengthened Electric Field Line Anode (SEFLA) detectors. Although the depth sensing had some limitation in practical application due to the non-uniform electric field, energy resolution was significantly improved from 3.2% (FWHM@662 keV) to 1.7%. Efforts will be made to apply this technique on the portable spectrometric systems based on SEFLA detectors.
