Revision of Booster to Storage Ring Transport Line Design and Injection Scheme for Top-Up Operation at NSRRC

In order to help the operation of constant current, the optics of booster to storage ring transport line (BTS) design is reinvestigated[1]. The initial Twiss parameters are derived by measurement. The optics of the transport line is readjusted according to the measured initial beam parameters. The design of pulse width of the injection kicker is also changed from 1.2 μs to 2.0 μs. The injection scheme is reviewed and the effects of the kicker error on both injected and stored beam are investigated and shown in this report.
