The photomultiplier gain monitoring system for the E687 electromagnetic calorimeter at Fermilab
Abstract
The nitrogen pulsed laser monitoring system for the outer electromagnetic calorimeter of the E687 photoproduction experiment, investigating charm and beauty states at the Fermilab Tevatron, is described. The system is reliable, economical and allows a photomultipliers gain stability control as good as 1%.
