A cryogenic search for WIMP Dark Matter with small sapphire bolometers thro
ugh the WIMP scattering off Al2O3 nuclei, the ROSEBUD (Rare Objects SEarch
with Bolometers UndergrounD) experiment, is being installed in the Canfranc
Underground Laboratory (Spain) at 2450 m water equivalent. The performance
s of the bolometers, the radioactive background expected from the measureme
nt of the radiopurity of the ROSEBUD components and the estimated sensitivi
ty of the experiment for low mass WIMP detection are presented. (C) 1999 El
