ELECTRON COOLING EXPERIMENTS AT FERMILAB. Academic Article uri icon

abstract

  • A 115 Mev proton beam has been successfully cooled in the Electron Cooling Ring at Fermilab. Initial experiments have measured the longitudinal drag force, transverse damping rate, and equilibrium beam size. The proton beam was cooled by a factor of aproximately 50 in momentum spread in 5 sec, and by a factor of 3 in transverse size in 15 sec. Long term losses were consistent with single scattering from residual gas, with lifetime approximately 1000 sec. Using the measured electron beam temperature T//e equals 0. 8(2) ev, the observed cooling agrees well with expectations from cooling theory.
