Challenges in Double Beta Decay
| NEXT-100 |
136Xe ( = 2457 keV) under construction |
| FWHM | 12.5 keV | MASS | 90 kg of 136Xe (100 kg of enriched Xe) | BKG | | Rejection | Event topology (predicted background rejection ratios are of 2 × 10−7 and detection efficiency of 25%) | Goal | 8 × 10−4 counts/(keV·kg·yr) (evaluation done on the basis of the background budget and rejection factors) | | 1.6 × 1026 yr in 5 years |
