Abstract

The performance of a "Loss-Free Counting" (LFC) method for pulse loss compensation is tested on two HPGe detectors; one with classical RC feedback preamplifier and another with Transistor Reset Preamplifier (TRP). Results are excellent on both, though extra fine-tuning precautions are required for the latter. Pulse loss by pileup is at the origin of an increased count variance in LFC spectra. A new formula for LFC uncertainty is presented and its validity demonstrated for a HPGe detector set-up.
