Universidad de Zaragoza (orcid)0000-0002-7158-9794 Light Yield of Undoped Sapphire at Low Temperature Under Particle Excitation 2005 Access copy available to the general public Unrestricted In this letter, we report on the performance of scintillating sapphire bolometers developed in the framework of the ROSEBUD (Rare Objects Search with Bolometers UnDerground) Collaboration devoted to dark matter searches. The simultaneous measurement of heat and light allows the discrimination of the type of particle increasing the sensitivity for these searches. A heat versus light negative correlation for gamma events has been observed. Its interpretation, in a simple framework, allows the estimation of the light yield of undoped sapphire at a temperature of about 20 mK under gamma, alpha, and neutron excitation. ¬© 2005 American Institute of Physics. info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 4.127 2005 PHYSICS, APPLIED 4 / 83 = 0.048 2005 Q1 T1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Beltrán, B.
