The Stanford Linear Collider Injector requires two 2 ns pulses of 4.5-5.5 x 1010 electrons, separated by 61 ns at 120 hz, from its source. Since 1992, these currents have been provided by a polarized electron source based on GaAs photocathodes. A beam polarization of 76 + 4% has been measured at the end of the 50 GeV linac. At low photocathode quantum efficiencies, and for excitation near threshold, the maximum current delivered by the source is constrained, not by the space charge limit of the… CONTINUE READING
