Detector for Detection of Electrons with an Energy of 5–30 keV for the “Troitsk Nu-Mass” Setup

A detector for detection of beta-decay electrons in experiments on recording of a signal of sterile neutrinos is searched for. A set of parameters indicates that an avalanche silicon precision detector is a promising detector that allows electron counting rates of up to 2.5 × 107 s–1 for an active area of 0.785 mm2 at room temperature with a possibility of spectrometric detection.
