Description
DEAP-3600 is a single-phase scintillation-only detector, which searches for dark matter particle interactions with 3.3 tonnes of liquid argon, located 2 km underground at SNOLAB (Sudbury, Ontario). The argon target is contained in an ultra-pure acrylic vessel viewed by 255 photomultiplier tubes.
The first DEAP-3600 WIMP-search results from 10 tonne-days of commissioning data were published last year, demonstrating the scintillation-only technique, the best achieved electronic-recoil backgrounds rejection using pulse-shape discrimination, lowest-ever achieved radon backgrounds in a noble liquid experiment, and demonstrating scalability to the very large target masses required to reach the neutrino floor.
The detector has been running stably since November 2016 and has accumulated exposure significantly exceeding the published dataset. This talk will present an overview of the project and status of the analysis of 1 year worth of data. Future plans for larger detectors will also be discussed.
