A technique for the reduction of pulse pile-up effect in pulse-shape discrimination of organic scintillation detectors

A technique for the reduction of pulse pile-up effect in digital pulse-shape discrimination (PSD) of neutrons and gamma-rays with organic scintillation detectors is presented. The technique is based on an electronic reduction of the effective decay-time constant of scintillation pulses while retaini...
