In Neutron time-of-flight facilities an intense flux of gamma-rays and high-energy particles commonly called gamma-flash is generated in the neutron production. Due to the high energy deposited, the gamma-flash often results in a saturated pulse, which may make the detectors blind for a long time and event produced by neutrons above few MeV cannot be detected. In order to decrease this effect we have developed a Charge sensitive preamplifier with an active circuit for an ultra fast de-saturation.

Abstract
In Neutron time-of-flight facilities an intense flux of gamma-rays and high-energy particles commonly called gamma-flash is generated in the neutron production. Due to the high energy deposited, the gamma-flash often results in a saturated pulse, which may make the detectors blind for a long time and event produced by neutrons above few MeV cannot be detected. In order to decrease this effect we have developed a Charge sensitive preamplifier with an active circuit for an ultra fast de-saturation.
