A Source of Reference Light Pulses for Stabilization of the Energy Scale of Fast Multichannel Scintillation Detectors

Energy-scale monitoring systems for scintillation detectors with various sources of standard light pulses are considered. A LED-based light-pulse generator with active quenching of afterglow, which can reduce the light-pulse duration by half, is described. The number of photons per pulse may amount to ∼109or more, the pulse duration being 10 ns. A long-term (a few weeks) instability of the light-flash intensity is ± 0.1%.
