用于等离子体韦克菲尔德加速的超音速气体射流方法在加速距离和能量方面具有限制，因为聚焦到小光斑尺寸的激光束在非常短的距离（~几mm范围）上严重衍射。为了避免衍射问题，可以使用毛细管等离子体源，其中高功率激光束可以通过毛细管等离子体通道中的抛物线等离子体密度分布在长距离（约几cm范围）上被引导。我们研制了一种用于产生GeV能级电子的充气毛细管等离子体源。本文介绍了GeV级电子束产生的详细实验结果和实验方案。
The supersonic gas jet method for plasma wakefield acceleration has a limitation in acceleration distance and energy because the focused laser beam to a small spot size is diffracted severely over a very short distance (~ a few mm range). To avoid the diffraction problem, a capillary plasma source can be used, where a high power laser beam can be guided over a long distance (~ a few cm range) by a parabolic plasma density profile in the capillary plasma channel. We have developed a gas-filled capillary plasma source for generation of GeV-level electrons. In this paper, the detailed test results and the experimental plan for GeV-level e-beam generation are described.
