Optimizing the average longitudinal phase of the beam in the SLC linac
The relation of the beam's average linac phase, {phi}{sub 0}, to the final energy spectrum in the SLC linac has been studied by many people over the years, with much of the work left unpublished. In this note we perform a somewhat thorough in vestigation of the problem. First we describe the calculation method, and discuss some common features of the energy spectrum. Then we calculate the value of {phi}{sub 0} that minimizes {delta}{sub rms} for the conceivable range of bunch population and bunch lengths of the SLC linac. This is followed by luminosity calculations, including the sensitivity of luminosity to variations in {phi}{sub 0}. Finally we suggest a practical method of implementing the proper phase setting on the real machine.
