Abstract
The rare objects search with bolometers underground (ROSEBUD) is an experiment to search for weakly interacting massive particles (WIMPs) at the Canfranc Underground Laboratory with bolometric detectors. We present the progress achieved in the second phase of the experiment with three different absorbers (Al2O3, Ge and scintillating CaWO4). For the first time, different target nuclei have been used simultaneously in a common set-up, sharing identical external background conditions. Moreover, a discrimination of nuclear against electron recoils based on the simultaneous measurement of light and heat has been developed and applied to derive limits for WIMP candidates.
