Freon filled bubble chambers have several characteristics that strongly complement other dark matter search techniques. Starting operation in 2023, PICO-500 will be the focus of PICO scientific efforts through this decade. Larger detectors require a candidate material to replace the synthetic silica as the inner vessel container. Several candidate materials are under investigation, and...
It has long been known that most of the matter in our Universe is dark. The direct detection of dark matter particle interactions is one of the most important topics in particle physics - a positive measurement would provide unambiguous evidence of the particle nature of dark matter in the Universe. In this talk we will present an overview of the phased approach to dark matter searches by the...
I will present the science case and the status of DARWIN, a liquid xenon time projection chamber (TPC) with a target mass of ~40 t. It will be sensitive to WIMP dark matter interactions down to the neutrino floor, the double beta decay of Xe-136, will allow for a precision measurement of low energy solar neutrinos, and will be sensitive to many other rare processes as well
Increased attention to low mass dark matter has necessitated the need for detectors with lowered energy thresholds. The Scintillating Bubble Chamber, to be installed at SNOLAB in 2022, builds on the world-leading work of the PICO collaboration, replacing the fluorine-based target with a noble liquid. The associated reduction in gamma sensitivity allows a much lower threshold to be set. Plans...
DarkSide-LowMass is a tonne-scale liquid argon time projection chamber (LAr TPC) being planned by the Global Argon Dark Matter Collaboration (GADMC) to search for dark matter candidates with masses below 10 GeV/c^2 by optimizing the TPC for an electron-counting analysis and using underground argon that has been further depleted in argon-39. The DarkSide-50 detector has previously set leading...
The proposed Oscura project plans to deploy a skipper-CCD detector with 10 kg of active mass to search for low mass dark matter at SNOLAB. This projects brings together the teams working in previous CCD and skipper-CCD experiments (DAMIC,SENSEI, DAMIC-M) and is currently in its R&D stage. I will discuss the scientific reach of this project, and its status and plans.
The NEWS-G collaboration searches for low mass dark matter particles with spherical proportional counters (SPCs) filled with light atomic mass gases. The current phase of the experiment, a 140-cm diameter SPC, is set to start searching for dark matter as soon as spring or summer 2021. The collaboration is planning to replace the commercial copper SPC with a fully electroformed SPC to be...
