The authors report on their continuing development of a cryogenic dark matter detector. 60 keV gamma pulses with sub-microsecond rise times have been observed in NTD germanium thermistors, consistent with our hot electron model. The authors have also developed a eutectic bonding method for attaching thermistors to a larger crystal, and discuss preliminary studies of the phonon transmission qualities of this technique. They report on the measurement of ionization created by particle interactions in a pure germanium crystal with applied bias fields as low as 1 V/cm.
