Abstract

Thanks to very high energy resolutions, low energy thresholds and very high sensitivity to nuclear recoils, cryogenic thermal detectors my play an important role in study and search dark matter particles of the universe. Milano group works with this type of detectors since many years and, at presents, operates the bigger cryogenic thermal detector with a total mass of 6.8 kg of TeO2 crystals segmented in 20 active channels. This detector is in operation since 1998 and has realized to search for double beta decay of Te-130. As a by product of this measurement also dark matter study will be conducted and, especially in the last year, a strong effort was made to further reduce threshold and spurious background in low energy region. The preliminary data on WIMPs searches with this detector is here reported. The improvement of this experiment will be the realization of the CUORICINO detector. Some preliminary tests on this new detector will be presented and briefly discussed.
