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，以便为先进韦克场实验（AWAKE）做出重要贡献，该实验是等离子体尾场加速（PWFA）研究领域的全球领先项目之一。在过去的十年中，等离子体中诱导尾场的加速方案已证明梯度超过 GV/m，比现有射频技术高出 3 个数量级以上，并有望为粒子物理、X- 等领域提供更紧凑、更实惠的未来加速器。射线科学和医学应用。 PWFA 项目中的独特之处和同类首创是由来自 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非常引人注目。与此同时，通过长质子束在毫米长度范围内实现与等离子体波的同步是一个挑战。因此，该实验的一个主要焦点是证明一种新颖的机制，即等离子体内部的质子束纵向自调制，这对于这一概念的成功至关重要。第一批质子预计将于 2016 年初投入实验。
