    DarkSide-20k is a 20 tonne fiducial mass liquid argon TPC that will perform an instrumental background-free search for WIMP dark matter. The TPC will be outfitted with more than 125,000 silicon photomultipliers (SiPM) grouped into 5210 single-channel, $25\ {\rm cm}^2$ photosensors that are sensitive to single photoelectrons. We will present the performance of the photosensor and associated...

    The LUX-ZEPLIN (LZ) detector is a next generation dark matter detector that will use a 7 active tonne liquid xenon time projection chamber (LXe-TPC) to search for dark matter particles, among other rare phenomena. The LZ project was approved in 2014 to continue toward fabrication and is now in the construction phase. In this talk, I will give an update on the current status and schedule of the...

    The LUX-ZEPLIN (LZ) dark matter experiment will consist of 7 active tonnes of liquid xenon sensitive to the nuclear recoils induced by impinging weakly interacting massive particles (WIMPs). Backgrounds to a WIMP signal tend to populate the boundaries of the LZ sensitive volume, where gamma-rays and neutrons from nearby material can enter, scatter once, and exit. The Outer Detector (OD) of...

    Talk

    In many experiments searching for rare nuclear processes, like direct interactions of cold dark matter particles, an extremely low radioactive contamination level of the detector target and the surrounding materials has to be achieved. This is only possible after implementation of an extensive R&D program and careful material screening with appropriate devices. Selected ultra-sensitive...
