Upgrade for Phase II of the Gerda experiment


GERDA Collaboration; Baudis, Laura; Brown, Adam; Capelli, Chiara; Manfredini, Alessandro; Galloway, Michelle; Reichard, Shayne; Volta, Giovanni; Peres, R; et al (2018). Upgrade for Phase II of the Gerda experiment. European Physical Journal C - Particles and Fields, 78(5):388.

Abstract

The Gerda collaboration is performing a sensitive search for neutrinoless double beta decay of 76Ge at the INFN Laboratori Nazionali del Gran Sasso, Italy. The upgrade of the Gerda experiment from Phase I to Phase II has been concluded in December 2015. The first Phase II data release shows that the goal to suppress the background by one order of magnitude compared to Phase I has been achieved. Gerda is thus the first experiment that will remain “background-free” up to its design exposure (100 kg year). It will reach thereby a half-life sensitivity of more than 1026 year within 3 years of data collection. This paper describes in detail the modifications and improvements of the experimental setup for Phase II and discusses the performance of individual detector components.
