Abstract

Electron cooling will be used to cool and accumulate antiprotons in the Fermilab p source. Successive p production cycles will be injected into the cooling ring with offset momentum, and coalesced into the stack using longitudinal electron cooling. The stacking performance of electron cooling is evaluated. It is shown that optimum p accumulation rate is obtained by increasing the cooling energy until the cooling time just matches the cycle time T0, for p production. For Fermilab Tevatron I this corresponds to Tp = 1.5 GeV, Te = 750 keV. The main features of the electron beam design are described. For a primary electron beam current Ie = 10A, we expect a loss current (to ground) Il ≲ 10mA and a transverse temperature T⊥ ˜0.25 eV.
