| Abstract | Scintillating bolometers of sapphire, BGO and LiF have been recently tested both at the Institut d'Astrophysique Spatiale (IAS) and the Laboratorio Subterraneo de Canfranc (LSC) in the frame of the ROSEBUD collaboration. We report on their response to different particles (alpha, beta, gamma and nuclear recoils) both in the heat and light channel. Signal output parameters for the different particles have been compared. We have focused on the study of the nuclear recoils discrimination against beta/gamma background events at low energy. The beta/gamma and nuclear recoil spectra obtained in the different runs are shown and analyzed. We also discuss the sensitivity of the LiF bolometer for measuring thermal neutron flux at LSC. |
