| Summary: | The possibility to use large amount of CdWO4 crystal scintillators to detect solar neutrino of low energies via neutrino
capture reactions on 116Cd is investigated. The detector concept is based on placing CdWO4 crystals in liquid scintillator
inside the sphere of 18 m in diameter, on which 9500 photomultipliers are installed. Such design makes possible
event to place reconstruction inside CdWO4 crystal with accuracy 1 mm for 1 MeV electrons. Thus, expected background
from random signal coincidences can be reduced to the rate ~300 events per year, which is of the same order
magnitude as expected neutrino signal (260 ± 65 events per year in 30 ton of CdWO4), taking into account neutrino
detection efficiency. |
