Description

The BetaCage is a proposed neon time-projection chamber for the ultra-sensitive (and nondestructive) screening of material surfaces for alpha- and beta-emitting contaminants, such as those due to implantation of radon progeny. The expected sensitivity is 0.1 betas per keV-m^2-day and 0.1 alphas per m^2-day. I will describe the detector design, results from background simulations, and results from a prototype.
