Abstract | |||||||||||||
| The Ge and Si detectors developed by the Cryogenic Dark Matter Search (CDMS) II experiment rely on the simultaneous detection of athermal phonons and ionization produced by interactions in the crystal. The athermal phonons not only provide the total energy deposited during an interaction, but also carry information about the position of the interaction. We describe extracting this information from the pulse shapes in the four phonon sensors arrays. We present the result of measurements made on a Si detector from the first CDMS II production batch. We also investigate ways of using the event position information to extract further information about the phonon signal and about the detector itself. | |||||||||||||
