Abstracts

EN

Low background scintillation setup has been developed that exhibits 3 orders of magnitude lower counting rate of a large volume (2.1 kg) CdWO₄ detector in the energy region 0.5-2.6 MeV, and one order of magnitude above 3 MeV. The background reduction was achieved by application of radiopure passive shield, active plastic-scintillation muon veto placed above the setup and pulse-shape discrimination. Construction of additional plastic scintillation counters is in progress to reduce the residual cosmic muons background. The setup can be applied to develop radiopure scintillators, measure radioactive contamination of materials, carry out small scale low counting experiments.
