Abstract
The transfer of energy from the driving beam to the trailing beam in the plasma wake-field accelerator is studied in computer simulations. We show that with an asymmetric current distribution in the driving bunch, trailing particles can gain energies up to (1+kp2Z2)12"mc2, where Z is the bunch length and "mc2 the average energy loss of driving electrons. Because of the relative phase slippage and the two-stream instability, the process of energy gain degrades before the driving beam loses all of its energy; however, even for i=150, "i70%, with an energy gain 1 GeV. Transverse effects are briefly discussed. © 1986 The American Physical Society.
