Paper Abstract

In the Plasma Wakefield Accelerator (PWFA) scheme a short bunch of high current (density nb), but low voltage electron beam is shot through a dense plasma. For a properly shaped bunch the background plasma electrons are adiabatically displaced from their initial positions and are subsequently released after the bunch has passed, resulting in a plasma wakefield. A trailing low current bunch can be accelerated by the plasma wakefield to energies on the order of.-1-11ln y0 mc2 when the driving bunch is appropriately shaped. The plasma thus acts like a transformer since it increases voltage at the expense of current. This scheme is thus in the general class of wakefield transformers, except that transformer ratios greater than 2 can be obtained even for axial co-propagating beams. In this paper we win describe recent work at UCLA on the PWFA.
