Abstract
The Cryogenic Dark Matter Search (CDMS) ZIP detectors utilize quasiparticle trapping as the mechanism for coupling the energy of a particle interactio n in the Ge (or Si) absorber into a tungsten (W) transition edge sensor (TE S). Consequently, the dynamics of quasiparticle propagation and loss signif icantly impact the energy collection and resolution of the detector. This p aper describes the considerations necessary in optimizing the detector surf ace geometry in order to have maximal quasiparticle collection. (C) 2000 El sevier Science B.V. All rights reserved.
