论文摘要
先进的韦克菲尔德实验（Awake）是Cern的加速器研发实验，首次使用高能量质子束，可将Wakefield驱动在等离子体中，并将电子加速到GEV能量量表。描述了清醒实验的原理。我们显示了长400 GEV SPS质子束的种子自调制过程的实验结果，将束变成了一系列微型堆，并在10 m长的RB等离子体中共同驱动了Wakefields。我们还表明，这些韦克菲尔德可以将外部注射的电子加速到几个GEV。显示了清醒实验程序的下一步。描述了该方案利用质子束中存储的大能量以达到单个等离子体中的高能量增益的优势，可能的第一应用可能的第一应用。
The Advanced Wakefield Experiment (AWAKE) is an accelerator R&D experiment at CERN using, for the first time, a high-energy proton bunch to drive wakefields in plasma and accelerating electrons to the GeV energy scale. The principle of the AWAKE experiment is described. We show experimental results of the seeded self-modulation process of the long 400 GeV SPS proton bunch, transforming the bunch into a train of micro-bunches and driving resonantly the wakefields in the 10 m long Rb plasma. We also show that externally-injected electrons can be accelerated by these wakefields to several GeV. The next steps of the AWAKE experimental program are shown. Possible first applications to high-energy physics experiments, where the scheme takes advantage of the large energy stored in the proton bunch to reach very high energy gain in a single plasma, are described.
