Phase space cooling and anti pp colliding beams of Fermilab
- Fermi National Accelerator Lab., Batavia, IL
It has recently been suggested that the present high energy synchrotrons at CERN and Fermilab could be operated as anti pp storage rings with a center-of-mass energy of some 800 GeV. The Fermilab Energy Doubler/Saver, in addition, would be quite suitable as a high performance storage ring, producing collisions at 2 TeV in the center-of-mass. In order to achieve useful luminosity it is necessary to: (1) collect antiprotons from approximately 80 GeV protons colliding on a stationary target; (2) cool the phase space of the initially diffuse anti p's; and (3) accumulate the cooled anti p's over cycles. One method of phase space cooling, that of electron cooling, has recently been demonstrated. In order to adapt this technique to antiproton cooling, one faces the problem that phase space compression with electrons works efficiently only at nonrelativistic energies, while the greatest majority of anti p's are produced fast in the laboratory system. The region between the optimum production and cooling energies for antiprotons may be covered by the introduction of a deceleration stage between the production of anti p's and the subsequent electron cooling. A design was developed to use the rapid cycling Fermilab booster to decelerate anti p's to 200 MeV where electron cooling and stacking could be performed in a modest cooling ring which could be housed in the booster tunnel.
