Track detector DEVIS for the double beta decay investigation

Detector DEVIS is TPC in the magnetic field. It is dedicated to the investigation of the double-beta decay of Xe. Setup sensitivity was estimated in the series of measurements with Xe with natural isotopes composition. Detector allows measuring two-neutrino double-beta decay of ${}^{136}$Xe with half-life less than $3\cdot {10}^{20}$ years.
