摘要：

We describe the counting and background characteristics of the multielement proportional chamber used for the search on two-neutrino and neutrinoless double beta decay of 136Xe in the Gran Sasso underground laboratory. Enriched xenon to 64% in the 136Xe isotope and natural xenon cleaned by ultracentrifugation were filled up to 9.5 bar and counted for 6210 and 5120 h, respectively. The reduction of chamber background using suitable software triggers is discussed in detail.
