Abstract :
The paper presents an interesting way of overcoming the well-known "polarization effect" in Cl-doped CdTe detectors. The detection efficiency is kept constant as long as the sample remains totally depleted, even though hole detrapping may occur from deep levels. Excellent stability has been checked for periods of time up to half an hour.
