Proton-driven plasma wakefield acceleration has been demonstrated in simulations to be capable of accelerating particles to the energy frontier in a single stage, but its potential is hindered by the fact that currently available proton bunches are orders of magnitude longer than the plasma wavelength. Fortunately, proton micro-bunching allows driving plasma waves resonantly. In this paper, we propose using a hollow plasma channel for multiple proton bunch driven plasma wakefield acceleration and demonstrate that it enables the operation in the nonlinear regime and resonant excitation of strong plasma waves. This new regime also involves beneficial features of hollow channels for the accelerated beam (such as emittance preservation and uniform accelerating field) and long buckets of stable deceleration for the drive beam. The regime is attained at a proper ratio among plasma skin depth, driver radius, hollow channel radius, and micro-bunch period.

This contrasts to wave characteristics in uniform plasmas, where regions of simultaneous deceleration and focusing are as short as a quarter of the wave period for low-amplitude waves [35] and even shorter for nonlinear waves and positively in nonlinear regime charged beams [10,162].

“…Mismatching the bunch frequency and the plasma frequency cannot solve the problem, since the required extension of the bunch-to-bunch distance depends on the bunch position in the train [23]. For example, the second bunch strongly modifies the wakefield of the first bunch and is focused if located about (2π + π/4)c/ω p behind the first bunch [ Fig.…”
