Funding: Work supported [optional: in part] by the U.S. Department of Energy under contract number DE AC0276SF00515. Plasma wakefield studies are normally conducted as single-shot experiments. Here, single-shot means that the plasma returns to its original state before the next bunch passes through the plasma. The time scale for the plasma to return to equilibrium is 10-100 ns, which is comparable to the bunch separation in proposed linear colliders. The SLAC linac typically delivers beam at a rate of 10 Hz to FACET but can be operated in a manner that delivers two electron bunches per RF pulse. We explore operation modes with beam separations as small 5.6 ns so that high repetition rate plasma wakefield acceleration can be studied at FACET. |
