质子驱动的等离子体韦克菲尔德场加速允许能量从质子束通过等离子体电子转移到尾随的粒子束，即“见证”粒子。欧洲核子研究中心的AWAKE实验正在使用欧洲核子研究中心SPS的质子束来演示这一方案。假设AWAKE计划继续取得成功，高能电子或μ子束将成为可用的，开辟了一系列广泛的未来粒子物理项目，从束流收集器搜索新的弱相互作用粒子，如暗光子，到固定目标物理计划，到能量前沿电子-质子，电子-离子，电子-正电子和μ子对撞机。现在是时候让粒子物理学界为追求这项新技术提供强有力的支持了，因为它将为高能粒子物理开辟新的途径。
Proton-driven plasma wakefield acceleration allows the transfer of energy from a proton bunch to a trailing bunch of particles, the `witness' particles, via plasma electrons. The AWAKE experiment at CERN is pursuing a demonstration of this scheme using bunches of protons from the CERN SPS. Assuming continued success of the AWAKE program, high energy electron or muon beams will become available, opening up an extensive array of future particle physics projects from beam dump searches for new weakly interacting particles such as Dark Photons, to fixed target physics programs, to energy frontier electron-proton, electron-ion, electron-positron and muon colliders. The time is right for the particle physics community to offer strong support to the pursuit of this new technology as it will open up new avenues for high energy particle physics.
