A scintillating bolometer is a scientific instrument used in the search for dark matter. It works by simultaneously measuring both the light pulse and heat pulse generated by a particle interaction within its internal scintillator crystal.
It was developed by scientists at the CNRS Institut d'Astrophysique Spatiale and the University of Zaragoza as part of the proposed ROSEBUD particle detector experiment in the Canfranc Underground Laboratory. It uses a bismuth germanate (Bi4Ge3O12, "BGO") detector crystal.
