PCA proposed in ** creates unstable plasma oscillations using modulation of a plasma frequency by means of the modulation of the transverse beam size using strong field solenoids. Instead we propose to use modulation of the average longitudinal velocity of electrons replacing the solenoids by the wiggler magnets. This approach promises obtaining a more compact amplifier due a more efficient modulation of the plasma frequency, although it requires separation of the hadron and the electron orbits in the amplifier region.
