Heavy ion driven plasma wakefield acceleration with drift-like phase-shift acceleration scheme
Abstract
Traditional plasma density modulation schemes can extend the dephasing length but suffer from wakefield degradation as plasma density increases. To address this limitation, a drift-like phase-shift acceleration scheme is proposed, introducing drift sections between plasma cavities to enable controlled phase shifting and avoid dephasing. Idealized simulation results show that electrons are accelerated from 16 MeV to 700 MeV within 1.65 m with an energy spread of 5\%. Furthermore, segmented simulations introducing realistic active plasma lenses verify the practical feasibility of this scheme, electrons are accelerated up to 720.5 MeV with a reduced energy spread of 3.3\% within 1.67 m. The plasma wakefield maintains a robust amplitude throughout the propagation, suggesting the potential for continued acceleration beyond the simulated region. This scheme demonstrates a promising way to enable the witness beam to gain energy continuously from the tail to the head of the driver beam and provides a new approach for generating high-energy, high-quality beams in heavy ion driven plasma wakefield acceleration.
