We have recently developed a scanning optical pulser for the precise measurement of device-to-device reproducibility, position-dependent response, and other important characteristics of low-temperature particle detectors. By making maps of the reflected light, we can measure the position of the detectors (mounted on the ADR) under the scanner (mounted on the 3K flange) to micro-meter precision . We find that the detector position typically changes approximately 3-4 μm from ADR regeneration to ADR regeneration . Further, when the ADR is allowed to warm at zero field over many hours from its base temperature to approximately 1 K, an additional change in …
