Аннотация:
A design of a large volume time projection chamber (TPC) for double beta decay measurements with solid samples is presented. The total surface of measured samples can be up to 2.5 m<sup>2</sup>. The chamber will operate in a magnetic field up to 0.07 T. The expected spatial resolution is better than 1 mm in electron drift direction and about 2 mm along the sense wires. The momentum resolution of about 10% should be reached. The background of the TPC will be very effectively suppressed by the visualization of each event. The TPC operating in an underground laboratory should reach a limit on the half-life of neutrinoless double beta decay of 10<sup>24</sup> years.
