The current status of "Troitsk nu-mass" experiment in search for sterile neutrino

Understand

We propose a new experiment to search for a sterile neutrino in a few keV mass range at the "Troitsk nu-mass" facility.

• The expected signature corresponds to a kink in the electron energy spectrum in tritium beta-decay.
• The new goal compared to our previous experiment will be precision spectrum measurements well below end point.
• The experimental installation consists of a windowless gaseous tritium source and a high resolution electromagnetic spectrometer.
