چکیده
|
Next-100 is an electroluminescent high-pressure xenon gas time projection chamber that will search for the neutrinoless double beta (0νββ) decay of 136xe. the detector possesses two features of great value for 0νββ searches: energy resolution better than 1% fwhm at the q value of 136xe and track reconstruction for the discrimination of signal and background events. this combination results in excellent sensitivity, as discussed in this paper. material-screening measurements and a detailed monte carlo detector simulation predict a background rate for next-100 of at most 4 × 10−4 counts kev−1 kg−1 yr−1. accordingly, the detector will reach a sensitivity to the 0νββ-decay half-life of 2.8 × 1025 years (90% cl) for an exposure of 100 kg·year, or 6.0 × 1025 years after a run of 3 effective years.
