“…Note that the background from natural radioactivity drops sharply above 2615 keV, which is the energy of the γ from 208 Tl decay ( 232 Th family). In addition, a contribution of cosmogenic activation, which is important problem of the next generation 2β decay experiments [8], decreases at higher energies.…”

“…However this parameter of CaWO 4 can vary significantly, a characteristic associated with difference in the quality of samples. Given the high interest in the use of a scintillating CaWO 4 in the experimental searches for rare events [2][3][4][5], the improvement of scintillation characteristic of the material is of primary importance.…”

Effect of thermo-chemical treatments on the luminescence and scintillation properties of CaWO4

In this work, we investigated the influence of thermal annealing in different atmospheres on the luminescence and scintillation properties of CaWO 4 . Luminescence and luminescence excitation spectra were examined using VUV synchrotron radiation. Thermal treatment causes change of the defect subsystem of the crystal, resulting in the alteration of the spectral dependences. The most obvious effect is the relative change in the intensity of the defect emission band which is excited below the fundamental absorption edge 4.7 eV. Studies of the scintillation kinetics and light yield carried out over a temperature range 8-300 K showed that former does not change upon the treatment, in contrast to the intensity of scintillations. It is found that $50% increase of the scintillation response can be achieved for CaWO 4 samples annealed in hydrochloric acid.

“…48 Ca, which will be employed in the CANDLES [1] and CARVEL [2] experiments, is a 0νββ candidate with both significant challenges and benefits. The low natural abundance of 48 Ca, less than 0.2 %, makes it difficult to secure a large amount of the isotope for experiments, and the phase-space factor is hampered by the low Z of Ca.…”
