STACEE (Solar Tower Atmospheric Cerenkov Effect Experiment) is a ground-based gamma-ray telescope. Using a large array of mirrors from a solar heliostat facility to capture Cerenkov light from gamma-ray showers in the atmosphere, STACEE plans to lower the threshold available to ground-based gamma-ray telescopes. Determining the threshold of STACEE is reliant upon understanding the components of the telescope. The photomultiplier tubes used to convert the Cerenkov light to electronic signals need to be carefully characterized as a part of this process. We describe a method to determine the gain of the photomultiplier tubes using an uncalibrated light source. Using a statistical model, the output distribution of a photomultiplier tube with a fixed-amplitude, pulsed light source can be used to determine the gain.
