Description

We have developed an on-line LED monitoring system for the scintillation counters of the experiment PHOENICS at the 3.5 GeV electron stretcher ring ELSA in Bonn. The LED light output proved to be stable within 0.3% concerning pulse height and within 15 ps concerning deviation in time measurement. Usually discussed disadvantages of LEDs like temperature dependence, ageing and the bad spectral match with the photomultiplier sensitivity were checked and are well under control. (orig.)
