A key issue in the search for Gravitational Waves (GWs) by the Advanced Laser Interferometer Gravitational Wave Observatory (LIGO) and Advanced Virgo detectors surrounds the presence of excess noise transients (glitches) that pollute the detector data. These glitches come from a range of sources and can often mimic the form of real astrophysical events. To distinguish between real events and...
SNO+ designed an Umbilical Retrieval Mechanism (URM) to deploy radioactive sources for the calibration of the detector. The sealed URM must maintain a near zero differential pressure between itself and the air pressure in the underground laboratory thus requiring a Pressure Equalizing System.
The Pressure Equalizing System consists of a Cover Gas Bag designed to adjust its volume to...
Construction materials for equipment used in experiments contain natural radioactivity. High energy photons and beta rays towards the end of the uranium and thorium chains can act as a source of background for experiments like the original SNO experiment. To mitigate this, construction materials are required to be ultra low radioactivity materials. This requires methods to measure the...
The PICO experiment utilizes a bubble chamber to search for weakly interacting massive particles (WIMPs). Events in the detector generate acoustic signals due to bubble creation caused by energetic incident particles, e.g., alpha particles, neutrons, gammas, or WIMPs. A use of these acoustic signals is to distinguish among the different events triggered by different types of incident...
