The design of the antiproton source for the Fermilab Tevatron I project incorporates two separate rings. The Accumulator Ring uses a stochastic cooling/stacking system to accumulate a sufficient number of antiprotons for use in the collider; the Debuncher Ring rotates buckets and debunches antiproton pulses from the production target. This requires, in the Debuncher, a choice of lattice transition energy very near the beam energy, resulting in a very narrow spread in the circulation frequency. If the energy spread could be further reduced in the Debuncher before the beam is transferred to the Accumulator, operational improvements would result in the reduction of stochastic cooling power in the Accumulator, the acceptance of a larger momentum bite of antiprotons in the Debuncher, and the reduction of momentum aperture in the Accumulator. On the other hand, the small value of the dispersion in revolution frequency with the particle momentum places severe performance criteria on the depth and frequency of a notch filter used in a stochastic momentum precooling system. This paper describes a quick investigation of the feasibility of precooling within the framework of technically achievable parameters.
