Description

The DEAP-3600 dark matter detector uses 255 photomultiplier tubes (PMTs) to detect scintillation light induced in liquid argon by nuclear recoils caused by hypothetical WIMPs. We present here two systems that are used to calibrate and monitor the properties of the PMTs and the overall detector response. The fi rst calibration method utilizes an LED optical flasher source, deployed directly inside DEAP-3600 and extracted before the detector is filled with liquid argon. In the second calibration system, which is installed permanently in the detector, light reaches the PMTs through a fi bre optic cables connected to injection points located in their vicinity. Details of both systems and their installation will be presented, together with the simulated performance.
