An optimized digital shaping filter has been developed for the Gerda experiment which searches for neutrinoless double beta decay in $$^76$$<sup>76</sup>Ge. The Gerda Phase I energy calibration data have been reprocessed and an average improvement of 0.3 keV in energy resolution (FWHM) corresponding to 10 % at the $$Q$$Q value for $$0\nu \beta \beta $$0νββ decay in $$^76$$<sup>76</sup>Ge is obtained. This is possible thanks to the enhanced low-frequency noise rejection of this Zero Area Cusp (ZAC) signal shaping filter.

Abstract

An optimized digital shaping filter has been developed for the Gerda experiment which searches for neutrinoless double beta decay in $$^76$$⁷⁶Ge. The Gerda Phase I energy calibration data have been reprocessed and an average improvement of 0.3 keV in energy resolution (FWHM) corresponding to 10 % at the $$Q$$Q value for $$0\nu \beta \beta $$0νββ decay in $$^76$$⁷⁶Ge is obtained. This is possible thanks to the enhanced low-frequency noise rejection of this Zero Area Cusp (ZAC) signal shaping filter.
