The CRESST-II direct Dark Matter search is located in the Gran Sasso
laboratories. CaWO4 crystals have been used as scintillating targets for WIMP
interactions. They are operated as cryogenic calorimeters in combination with a
second cryogenic detector used to measure the scintillation light produced in the
target crystal. For each particle interaction, the combination of phonon and light
signals enables an event by event discrimination which allows distinguishing
particles (alphas, betas, gammas, neutrons) from the expected signal of weakly
interacting massive particles (WIMPs).
After a major upgrade of the setup, the experiment has been successfully
and data from the commissioning phase are presented here. Combining the
collected with the two detector modules running in this phase with the data
single module obtained during the previous prototyping run, the experiment
already place a limit of 5.3×10-7 pb for the spin independent scattering cross
section for WIMPs of 60 GeV/c2 mass.
Finally a brief report on the status of the ongoing data taking phase with 17
detector modules installed will be given.
