Title: Status of the Germanium Detector Array (GERDA) in the search of neutrinoless {beta}{beta} decays of {sup 76}Ge at LNGS

Abstract

The Germanium Detector Array (GERDA) in the search for neutrinoless {beta}{beta} decays of {sup 76}Ge at LNGS will operate bare germanium diodes enriched in {sup 76}Ge in an (optional active) cryogenic fluid shield to investigate neutrinoless {beta}{beta} decay with a sensitivity of T{sub 1/2} > 2 x 10{sup 26} yr after an exposure of 100 kg yr. Recent progress includes the installation of the first underground infrastructures at Gran Sasso, the completion of the enrichment of 37.5 kg of germanium material for detector construction, prototyping of low-mass detector support and contacts, and front-end and DAQ electronics, as well as the preparation for construction of the cryogenic vessel and water tank.
