A New Technique for the Identification of Surface Background: The Surface Sensitive Bolometers.

Abstract  The main problem for experiments using the bolometric technique to search for rare events is the contribution of surface contamination to the background. In this paper a new technique for the identification of the origin of events will be described. The idea is to shield the main bolometer with bolometric shields. Tests on small and large prototypes and the promising results will be reported. [ABSTRACT FROM AUTHOR]
