Hv. Klapdorkleingrothaus et Yg. Zdesenko, ICE SHIELDING IN THE LARGE-SCALE GENIUS EXPERIMENT FOR DOUBLE-BETA DECAY AND DARK-MATTER SEARCH, The European Physical Journal. A: Hadrons and Nuclei, 3(2), 1998, pp. 107-108
We suggest here the use of ice as shielding material in the large scal
e GENIUS experiment for the ultimate sensitive double beta decay and d
ark matter search. The idea is to pack a working volume of several ton
s of liquid nitrogens, which contains the ''naked'' Ge detectors, insi
de an ice shielding. Very thin plastic foil would be used in order to
prevent leakage of the liquid nitrogen. Due to the excellent advantage
s of ice shielding (high purity and low cost, self-supporting ability,
thermo-isolation and optical properties, safety) this could be anothe
r possible way of realization of the GENIUS project.
