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.

该提案为加拿大寻求资金，为高级韦克菲尔德实验（Awake）做出重要贡献，这是血浆韦克菲尔德加速（PWFA）研究领域的主要全球项目之一。在过去的十年中，血浆中引起的韦克菲尔德的加速度方案表现出超过GV/m的梯度，比现有射频技术高3个数量级以上，并且有望在粒子物理，X射线科学和医疗应用方面更加紧凑，更实惠的未来加速器。在PWFA项目中，首先是由CERN SPS同步加速器驱动的清醒实验。质子单阶段能量转移的潜力及其比多阶段电子驱动替代方案的优势令人信服。同时，通过长质子束以mm长度比等离子体波实现同步是一个挑战。因此，实验的主要重点是证明血浆内部的一种新型机制，质子束纵向自调节，这对于该概念的成功至关重要。预计该实验的第一个质子是2016年初。
