CRESST Dark Matter Search: Results of Phase I
Results of Cresst experiment in Gran Sasso using 262g sapphire
crystals with tungsten phase transition thermometers are
presented. Data taken with CRESST phase I have been used to place
limits on WIMP dark matter particles in the galactic halo. The
sapphire detectors are especially sensitive for low-mass WIMPS with
spin dependent interaction and improve on existing limits in this
region. CRESST is now preparing for a second phase, which will use
CaWO4 crystals with coincident detection of phonons and scintillation
light to suppress the radioactive background.
