The suggestion that $$\overline{p}s$$ be decelerated in the precooler and transferred directly to the ECR, thereby bypassing the booster, seems to keep re-appearing. We propose to collect ± 2% Δp/p at about 4 GeV. Δp/p will grow by about 8 after deceleration to 200 MeV. If we assume that the useful momentum acceptance of the ECR during cooling/stacking is ± 0.3% or so (the transverse emittance may be larger than that of the booster), this would require a momentum cooling factor of 50 or so in the precooler to transfer the beam to the ECR in one load.
