Mv. Korzhik et al., A source of reference light pulses for stabilization of the energy scale of fast multichannel scintillation detectors, INSTR EXP R, 44(4), 2001, pp. 485-490
Energy-scale monitoring systems for scintillation detectors with various so
urces of standard light pulses are considered. A LED-based light-pulse gene
rator 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 similar to 10(9) or more, the pulse duration being 10 ns. A long-term (
a few weeks) instability of the light-flash intensity is +/-0.1%.
