Flat beam studies in the SLC Linac

The Stanford Linear Collider (SLC) was recently converted to flat beam operation (/spl gammaspl epsivsub x/=10 /spl gammaspl epsivsub y/), producing a factor of two increase in luminosity. In this paper we review the results of flat beam studies in the SLC Linac. In summary, the injected beams from the damping rings had invariant horizontal emittances as low as 30 mm-mrad and invariant vertical emittances as low as 2 mm-mrad. The emittances measured at the end of the linac after tuning for 3/spl times/10/sup 10/ particles are about 5 to 8 mm-mrad vertically and 40 to 50 mm-mrad horizontally. Flat beam operation began 3/17/93.<
