Status of the GERDA Experiment at the Laboratori Nazionali del Gran Sasso
Figure 14
(a): Energy spectrum for the sum of all Ge detectors in the range 2020–2060 keV, without PSD (empty histogram) and with PSD (black histogram). The red dashed curve is the expectation based on the central value of [19]; the blue curve is instead based on the 90% upper limit derived by GERDA, = 2.1 yr. (b): Energy spectrum in the range 1880–2240 keV; the vertical dashed lines indicate the interval 1930–2190 keV used for the background estimation. From [33].
