The Cryogenic Dark Matter Search (CDMS) and SuperCDMS experiments seek hypothetical weakly-interacting, massive particles (WIMPs) that could account for the majority of matter in the Universe, by means of cryogenic germanium detectors. We provide an update on the status of the SuperCDMS experiment, and discuss the joint CDMS-EDELWEISS analysis.

In a superconducting radio-frequency particle accelerator, such as that being developed at Fermilab, it is often important to measure the amount of ionizing radiation emitted by particles due to Bremsstrahlung and other effects, in order to protect the accelerator from damage. Excessive exposure of machine components to this type of radiation can result in a variety of failures. Cryogenic loss ...
