Rf Beam Deflection Measurements and Corrections in the SLC Linac

摘要

The requirements of rf acceleration in the SLC linac to produce high energy beams are complicated by the presence of small transverse rf beam deflections which arise from several sources. These rf deflections place stringent tolerances on the phase and amplitude stability of the klystrons. They also force the use of special magnetic bumps to correct the trajectories of oppositely charged beams that will pass down the linac. If left unabated, rf deflections can limit the performance of the SLC. There are several methods to reduce the deflections. Many measurements of rf deflections have been made in the low energy part of the linac where the beams are most sensitive. 4 refs., 8 figs., 2 tabs. (ERA citation 10:031909)
