Status of the ROSEBUD dark matter experiment in 1999

The ROSEBUD (Rare Objects SEarch with Bolometers UndergrounD) experiment co nsists of three small sapphire bolometers with NTD-Ge sensors operating at 20 mK in the Canfranc Underground Laboratory in an attempt to directly dete ct low mass Weakly Interacting Massive Particles (WIMPs) through their scat tering off Al and O nuclei. We report in this paper the results of three ru ns (about 10 days each) performed along 1999 and the progressive background reduction obtained essentially from modifications in the cryostat. A new r un is in progress to complete the first phase of the experiment.
