Abstract

One way to detect dark matter particles from the halo of our galaxy is to detect phonons generated by dark matter particle interaction in a crystal. We report on our efforts to develop a phonon detector operating at 20 mK. We present our recent results on the simultaneous measurement of phonons and ionization, which may provide an effective way to reject background in dark matter search.
