For the first time, a cadmium tungstate crystal scintillator enriched in$^{116}$ Cd has been succesfully tested as a scintillating bolometer. The measurement was performed above ground at a ...temperature of 18 mK. The crystal mass was 34.5 g and the enrichment level $\sim $ 82 %. Despite a substantial pile-up effect due to above-ground operation, the detector demonstrated high energy resolution (2–7 keV FWHM in 0.2–2.6 MeV $\gamma $ energy range and 7.5 keV FWHM at the$^{116}$ Cd double-beta decay transition energy of 2813 keV), a powerful particle identification capability and a high level of internal radio-purity. These results prove that cadmium tungstate is a promising detector material for a next-generation neutrinoless double-beta decay bolometric experiment, like that proposed in the CUPID project (CUORE Upgrade with Particle IDentification).
