This proposal seeks funding for Canada to make an important contribution to the Advanced Wakefield Experiment (AWAKE), one of the leading global projects in the field of plasma wakefield acceleration (PWFA) research. In the past decade acceleration schemes by induced wakefield in plasmas have demonstrated gradients in excess of GV/m, more than 3 orders of magnitude higher than existing radio frequency technology, and hold promise of more compact and affordable future accelerators for particle physics, X-ray science, and medical applications. Unique among PWFA projects and first of its kind is the AWAKE experiment driven by 400 GeV proton beam from the CERN SPS synchrotron. The potential of single-stage energy transfer by proton, and its advantage over multi-stage electron driven alternatives, are compelling. In the meantime achieving synchronism with the plasma wave at a mm length scale by the long proton bunch is a challenge. A major focus of the experiment is thus to demonstrate a novel mechanism, proton bunch longitudinal self-modulation inside the plasma, critical to the success of this concept. First protons to the experiment are expected early in 2016.

该提案寻求为加拿大提供资金，以便为高级韦克菲尔德实验作出重要贡献，该实验是等离子体韦克菲尔德加速研究领域的主要全球项目之一。在过去的十年中，通过等离子体中的诱导韦克菲尔德加速方案已经证明了超过GV/m的梯度，比现有的射频技术高出3个数量级以上，并且为粒子物理学、X射线科学和医学应用提供了更紧凑和负担得起的未来加速器。在PWFA项目中独一无二的是由CERN SPS同步加速器的400 GeV质子束驱动的AWAKE实验。质子单级能量转移的潜力及其相对于多级电子驱动替代方案的优势是引人注目的。同时，通过长质子束团实现与毫米级等离子体波的同步是一个挑战。因此，实验的一个主要重点是展示一种新的机制，质子束纵向自我调制等离子体内部，这一概念的成功至关重要。预计2016年初将有第一批质子进入实验。
