[en] The lower limits on the neutrinoless and two neutrino ββ-decay of 136Xe, obtained with a multi-element proportional chamber, are reported. The sensitivity of the experiment was limited by the level of the background contamination. The experimental apparatus, its performance and the background analysis are discussed in detail. (orig.)

[en] We are developing high resolution Si-implanted thermistors for a calorimetric neutrino mass experiment. The production process is being tuned to reach high performance and reproducibility. We discuss the properties of devices prepared with different process parameters and different geometries. We also present the results obtained using these thermistors for detecting low energy X-rays.
