Beta Cage: A New, Large-Area Multi-Wire Screening Detector For Surface Beta Contamination

We report on a design study for a new, dedicated, low-radioactive-background screening detector for low-energy beta-emitting contamination on surfaces. The detector, a large-area gaseous detector with multi-wire proportional readout, has sufficient sensitivity to screen materials at the level needed...

Description
Summary:We report on a design study for a new, dedicated, low-radioactive-background screening detector for low-energy beta-emitting contamination on surfaces. The detector, a large-area gaseous detector with multi-wire proportional readout, has sufficient sensitivity to screen materials at the level needed for the proposed SuperCDMS 1 ton dark matter experiment. Such capability does not currently exist. This detector would have additional applications in low-radioactive-background physics experiments, and radioactive trace analysis, such as 14C dating.
