This novel type of particle “cooling”, called Ionization Cooling, is applicable to slow ( ) ions stored in a small ring. The many traversals through a thin foil enhance the nuclear reaction probability, in a steady configuration in which ionisation losses are recovered at each turn by a RF-cavity. For a uniform target “foil”, typically few hundred v ≈ 0.1c μg cm thick, transverse betatron oscillations are “cooled”, while the longitudinal momentum spread diverges exponentially since — in the… CONTINUE READING
