OSTI ID:6285203
We have built a Time Projection Chamber for observing double beta decay in /sup 136/Xe. The chamber is currently being operated with an Argon-Methane gas mixture, and typical cosmic ray and low energy electron tracks are presented. The chamber is scheduled to be filled with xenon in the summer of 1987 and will be installed in the St. Gotthard (Switzerland) auto tunnel later in the year. We estimate that the TPC will have a sensitivity to Majorana neutrino masses less than 1.5 eV when filled with natural xenon and 0.5 eV if it is filled with enriched /sup 136/Xe. 6 refs., 4 figs.
