BGO scintillating bolometer: its application in dark matter experiments
BGO scintillating bolometer: its application in dark matter experiments.
Journal of Physics (Conference Series) 2010. Vol.203(2010)
In the frame of the ROSEBUD (Rare Objects SEarch with Bolometers
UndergrounD) collaboration, we have tested at surface level (Orsay) and underground
(Canfranc) properties at low temperature of a BGO scintillating bolometer developed as a
prototype for dark matter searches. The response of the detector to di®erent particles, both in
heat and light, using internal and external radioactive sources is reported. We have focused on
its sensitivity as dark matter target and as °{ray spectrometer to monitor external background.
An algorithm implemented to analyze high energy events, which produce saturated pulses in
low energy experiments (like dark matter searches), is also discussed.
