Description
Future large scale cryogenic dark matter experiments – such as EURECA or SuperCDMS - will focus on the exploration of low mass WIMPS reaching for unparalleled sensitivities for the cross section of spin-independent WIMP-nucleon interactions. This requires an unprecedented suppression of the background in the nuclear recoil band down to 1 event/ton/year in the region of interest. External and internal shielding together with an active veto system have to be installed to suppress multiple sources of background – an important of which being radiogenic and cosmogenic neutrons. In this poster, we will focus on the development of the SuperCDMS active neutron shied – a loaded scintillator in the vicinity of the detectors acting as a dedicated ambient neutron veto.
