Abstract
The mystery of Dark Matter in our universe has puzzled scientists over the past century, and a large number of experimental ventures have been conducted hoping to find an answer. The Weakly Interacting Massive Particle (WIMP) is a well motivated dark matter candidate with a number of direct detection experiments dedicated to finding WIMPs or excluding them from being the solution to the dark matter problem. SuperCDMS is a cryogenic dark matter experiment with semiconductor detectors currently being constructed in the underground low background laboratory SNOLAB, with plans to begin taking science data in 2023. The Cryogenic Underground TEst (CUTE) facility is presently operating at SNOLAB to test the detectors which will go in the SuperCDMS experiment, and perform preliminary science runs using SuperCDMS detectors in a low background, low noise environment. Calibrations of detectors is critical in order to understand and quantify the signals which they produce. The design, construction, and testing of the neutron calibration system planned to be installed in CUTE are highlighted, and an analysis of the collection efficiency of a detector was conducted by identifying the signal associated with 71Ge decay. This thesis also discusses the contributions to the improved performance of CUTE through noise studies, and cooldown optimization.
