A Veto for the ZEPLIN-III Dark Matter Detector

This event is part of the HEE Seminar Series.

Cold dark matter in the form of weakly interacting massive particles (WIMPs) is a favoured explanation to the galactic dark matter puzzle and could account for a large proportion of the missing mass of the Universe. The ZEPLIN-III detector aims to detect dark matter by utilizing liquid xenon as a target medium. A successful first science run has demonstrated the benefits of ZEPLIN-III’s unique high-field operation, open-plan geometry and use of radiologically clean materials. Further sensitivity reach is to be achieved by retro-fitting a high efficiency veto detector. This talk will present the requirements, design and simulation of the veto as well as presenting results from the first science run and also the potential of ZEPLIN-III in its upgraded state.
