Gallium sell-off threatens detector
Article Abstract:
Scientists at SAGE, an underground neutrino detector, refused to relinquish their 60 tons of ultrapure gallium to the ministry of fuel and power- production industries. Science minister Vladimir Fortov delayed the transfer. SAGE officials suspect the government plans to sell the gallium abroad.
