INITIAL COOLING EXPERIMENT (ICE)

<!--HTML-->ICE was built in 1977, using the modified bending magnets of the g-2 muon storage ring (see <a href="http://cdsweb.cern.ch/record/726710">7405430</a>). Its purpose was to verify the validity of stochastic and electron cooling for the antiproton project. Stochastic cooling proved a resounding success early in 1978 and the antiproton project could go ahead, now entirely based on stochastic cooling. Electron cooling was experimented with in 1979. The 26 kV equipment is housed in the cage to the left of the picture, adjacent to the "e-cooler" located in a straight section of the ring. With some modifications, the cooler was later transplanted into LEAR (Low Energy Antiproton Ring) and then, with further modifications, into the AD (Antiproton Decelerator), where it cools antiprotons to this day (2006).
