Abstract
A simple circuit is developed to maintain a constant anode current (< ± 1%) from a photomultiplier viewing Cherenkov light against wide fluctuations in the night sky background. This has enabled us to maintain a constant photon density threshold for the Cherenkov receivers while observing sources of gamma rays using the atmospheric Cherenkov technique. The circuit has a high figure of merit (= 625) and is fast enough to respond to atmospheric stellar scintillations in the frequency range of dc to 5 kHz.
