NEMO 3 And SuperNEMO
- Mount Holyoke College, South Hadley, Massachusetts 01075 (United States)
The NEMO 3 double beta decay detector has been running since February 2003. The first runs identified an unexpected abundance of radon within the detector. The successful solution to this problem is presented here. No evidence of neutrinoless double beta decay has been observed. The current limits are T{sub (1/2)}{sup 0{nu}} ({sup 100}Mo) > 5.8 x 10{sup 23}y and T{sub (1/2)}{sup 0{nu}} ({sup 82}Se) > 2.1 x 10{sup 23}y. The anticipated limits on neutrinoless double beta decay in five years for NEMO 3 are also presented. The design criterion for the next generation detector, SuperNEMO, are spelled out with restrictions on its resolution and radiopurity. The intended sensitivity for SuperNEMO, is to reach 1 to 2 x 1026y or an effective neutrino mass of 50 meV in 10 years, so as to probe the inverted neutrino mass hierarchy.
