MLL-Kolloquium: Dr. Tina Pollmann (Physik Department E15, TUM) :The DEAP-3600 dark matter experiment

Thursday 18 May 2017, 16:00 → 17:00 Europe/Berlin

Lecture Hall (ground floor west) (LMU building, Am Coulombwall 1, Garching)

Dark matter in the form of weakly interacting massive particles WIMPs) is currently the favoured explanation for the universe's missing mass problem, but efforts to directly detect such particles have so far been unsuccessful. The DEAP-3600 detector was built to detect WIMPs interacting in a 1 tonne liquid argon volume. Detection relies on the bright argon scintillation response, with pulse shape discrimination as the main method of background suppression. DEAP-3600 went online last fall and over a three year livetime will probe much of the theoretically favoured region of WIMP parameter space. This talk focuses on the operation principle, current status, and future plans of DEAP.
