Low-Background Assay Techniques

Presentation

Advancing the detection limits in experiments searching for rare nuclear processes, such as direct dark matter interactions and neutrinoless double beta decay, requires material selection with extremely low radioisotope content. Low-background, large-surface alpha spectrometry is one of the techniques used to measure low surface and bulk specific activities of alpha emitters. One of the most...

Low-Background Assay Techniques

Presentation

Xenon Time Projection Chamber (TPC) based experiments have long been among the most sensitive and successful approaches to direct dark matter detection. However, the present generation of detectors is approaching its sensitivity limits, thus, a larger detector of 60-80 tonne active liquid xenon target is envisioned as part of the XLZD collaboration. This detector is building upon the expertise...

Low-Background Assay Techniques

Presentation

The Low Background Group at SNOLAB supports rare-event physics experiments through ultra-low background measurements and material assays in one of the deepest underground laboratories in the world. The group provides capabilities in high-purity germanium gamma-ray spectroscopy, ICP-MS, alpha screening, radon measurements, and neutron measurements to support experiments in dark matter, ...
