The CRESST Dark Matter Search (15'+5')
 
The CRESST-II direct Dark Matter search is located in the Gran Sasso 
underground
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 
known
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 
commissioned
and data from the commissioning phase are presented here. Combining the 
data
collected with the two detector modules running in this phase with the data 
from one
single module obtained during the previous prototyping run, the experiment 
could
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.
