AP2 and Debuncher Acceptance Upgrades

One exceedingly difficult problem that must be overcome in the accumulation of antiprotons is that of gathering the antiproton beam, which has been created in a very large phase space volume at the production target, into the relatively small admittance of the accelerator responsible for accumulation. Any endeavor to increase the yield of antiprotons will require either an increase in the overall acceptance of the Antiproton Source or improvements in the means by which a large reduction in the phase space volume occupied by the $\overline{p}$ beam is accomplished. The focus of this document is on the plans to increase the acceptance of Antiproton Source components immediately downstream of the production target – the AP2 beamline and the Debuncher ring.
