The IceCube Neutrino Observatory is a large volume neutrino detector located two kilometers below the South Pole. Over one cubic kilometer of the ice is instrumented with 5,160 Digital Optical Modules (DOM) each containing a 10 inch diameter photomultiplier tube. The DOM’s photon acceptance has been measured in the lab, but does not accurately represent the behavior seen in ice. This disagreement in detector response impacts our ability to accurately reconstruct deposited energy. To compensate for these in situ effects, a charge scaling factor is applied to adjust simulation to more accurately describe data. This study utilizes a sample of minimum ionizing atmospheric muons, which emit a nearly constant and known rate of Cherenkov radiation, to measure the DOM charge scaling factor.
