“…The tritium β-decay spectrum, including INLs, is modeled by simulating the realistic signals as created by a Si-detector and read-out system, assuming an illumination of the detector with tritium β-decay electrons at high rates. The simulations use input of the software siggen [25], which is a dedicated software to generate signals in semi-conductor detectors, used by several experiments such as GRETINA and MAJORANA [26].…”
