Observation of a beam energy shift caused by a plasma wakefield

Technical Report:

Abstract

The energy shifts of linac electron beams caused by a plasma wakefield were measured in plasmas with a density on the order of 10{sup 12} cm{sup -3}. The linac provided a sequence of several bunches which generated a wakefield in the plasma. The wakefield, in turn, caused an energy change in the bunches. Data processing took account of the finite bunch length, which was comparable or even longer than the plasma wavelength. It shows that the observed wakefield, if converted into the values at the bunch center, amounted to {approx} 20 MeV/m in certain cases. The energy spectra were qualitatively consistent with the calculations. No buildup of the wakefield was obvious after the maximum bunch. (author).
