Russia: Gallium Sell-Off Threatens Detector
Andrey Allakhverdov and Vladimir Pokrovsky
MOSCOW--An extraordinary confrontation between scientists and a Russian government ministry is taking place at a mine in the north Caucasus. Deep underground, the Soviet-American Gallium Experiment (SAGE)--one of the largest collaborative research projects between the two countries--has been measuring neutrinos from the sun's nuclear processes since the mid-1980s. But a government effort to confiscate the detector's 60 tons of ultrapure gallium could end SAGE's vigil.
