The background in the 0νββ experiment Gerda
The GERmanium Detector Array (Gerda)experimentattheGranSassoundergroundlaboratory(LNGS)of INFN is searching for neutrinoless double beta (0���)decay of 76Ge. The signature of the signal is a monoen-ergetic peak at 2039 keV, the Q�� value of the decay. Toavoid bias in the signal search, the present analysis does notconsider all those events, that fall in a 40 keV wide regioncentered around Q . T...
متن کاملSurface projection of HPGe- detectors
Several encapsulated single Germanium detectors have been mounted in one unit and integrated in a cryostat, in order to build efficient spectrometers to detect γ radiation emitted by nuclei excited in nuclear reactions. This kind of crystal encapsulation offer advantages compared to standard set-up of HPGedetectors. The basic aim of the following work is to develop a new capsule technology, in ...
متن کاملOperation of a GERDA Phase I prototype detector in liquid argon and nitrogen
The GERDA (GERmanium Detector Array) experiment aiming to search for the neutrinoless double beta decay (0νββ) of Ge at the Laboratori Nazionali Del Gran Sasso (LNGS), Italy, will operate bare enriched high-purity germanium (HPGe) detectors in liquid argon. GERDA Phase I will use the enriched diodes from the previous Heidelberg-Moscow (HdM) and IGEX experiments. With the HPGe detectors mounted ...
متن کاملSearch for Double Beta Decay with Hpge Detectors at the Gran Sasso Underground Laboratory
Neutrinoless double-beta (0νββ) decay is practically the only way to establish the Majorana nature of the neutrino mass and its decay rate provides a probe of an effective neutrino mass. Double beta experiments are long-running underground experiments with specific challenges concerning the background reduction and the long term stability. These problems are addressed in this work for the Heide...
متن کاملPerformance of HPGe Detectors in High Magnetic Fields
A new generation of high-resolution hypernuclear γ-spectroscopy experiments with high-purity germanium detectors (HPGe) are presently designed at the FINUDA spectrometer at DAΦNE, the Frascati φ-factory, and at PANDA , the pp hadron spectrometer at the future FAIR facility. Both, the FINUDA and PANDA spectrometers are built around the target region covering a large solid angle. To maximise the ...
