【 摘 要 】

It requires Booster to be able to deliver 8-GeV proton beams to Main Injector at the intensity of 4.5 x 10{sup 12} per batch with a longitudinal emittance of 0.12 eV {center_dot} sec and a momentum spread ({Delta}p) of 18 MeV in order to achieve the antiproton production rate of 24 x 10{sup 10} per hour. Bunch rotation via the RFSUM reduction at the end of a cycle has been implemented to reach the goal. Afterward, it is important for us to develop diagnostic tools and tuning capabilities to make bunch rotation operationally reliable.
