Abstract
With the aim of improving the rejection of surface beta contamination on the CDMS ZIP detector, we have studied the effectiveness of our phonon pulse-shape discrimination by matching a Monte Carlo calculation to data from a 350 μ m long Al fin with W TESs (Transition-Edge Sensors) at both ends. From this fit, we determined the Al film diffusivity to be D Al = 0.010 ± 0.001 m 2 / s , the quasiparticle trapping length in the Al fin to be l trap = 180 ± 10 μ m , and the Al to W TES transmission to be f Al / W = 0.002 ± 0.001 .
