Generation and Acceleration of High Intensity Beams in the SLC Injector

A new gun pulser and substantially increased focusing have been added to the first 100 m of the SLAC linac in order to provide a pair of intense electron bunches to the SLC damping ring. Each bunch from this injector must have 5 x 10 10 electrons, an invariant emittance γε ≤ 1.8 x 10 -3 m-rad and th...

Description
Summary:A new gun pulser and substantially increased focusing have been added to the first 100 m of the SLAC linac in order to provide a pair of intense electron bunches to the SLC damping ring. Each bunch from this injector must have 5 x 10 10 electrons, an invariant emittance γε ≤ 1.8 x 10 -3 m-rad and the pair must have an energy spread of less than 2% . Wakefield instabilities present in earlier versions of this injector 1 have been controlled by reducing the transverse beam dimension by a factor of 3.
