TL;DR

This paper reports a new extreme blowout regime in proton-driven plasma wake-field acceleration, producing electric fields thousands of times stronger than previous designs, enabling potentially revolutionary particle acceleration capabilities.

Contribution

The study introduces a novel parameter regime in plasma wake-field acceleration that achieves unprecedented electric field strengths using high-density proton bunches.

Findings

Electric fields of about 2000 GV/m achieved

Extreme blowout regime occurs when proton density exceeds plasma electron density by 100 times

Potential for significantly enhanced electron acceleration

Abstract

Three dimensional particle in cell simulations are used for studying proton driven plasma wake-field acceleration that uses a high-energy proton bunch to drive a plasma wake-field for electron beam acceleration. A new parameter regime was found which generates essentially constant electric field that is three orders magnitudes larger than that of AWAKE design, i.e. of the order of $2 \times 10^{3}$ GV/m. This is achieved in the the extreme blowout regime, when number density of the driving proton bunch exceeds plasma electron number density 100 times.
