This paper deals with a new add-on circuit structure that swiftly de-saturates a charge preamplifier for ionizing-radiation detectors when an energetic event occurs, or when a burst of piled up events puts it into saturation. The circuit is conceived for experiments where a spurious background of energetic particles and photons exists, such those with exotic beams in the new generation of European and USA nuclear-physics facilities.

Abstract
This paper deals with a new add-on circuit structure that swiftly de-saturates a charge preamplifier for ionizing-radiation detectors when an energetic event occurs, or when a burst of piled up events puts it into saturation. The circuit is conceived for experiments where a spurious background of energetic particles and photons exists, such those with exotic beams in the new generation of European and USA nuclear-physics facilities.
