论文摘要
为了唤醒自我调制的质子束在等离子体中驱动韦克菲尔德。最近的实验成功证明了驱动束自调制以及测试电子的加速度的许多方面。下一个实验将集中于生产具有低发射率和低能量传播的多GEV加速电子束。该实验需要各种高级梁诊断，以表征Picsecond Time量表的自我调节质子束。其中包括光学过渡辐射和条纹摄像头，用于短期和长时间的自调调制和围质的详细成像，用于100-300 GHz频率范围内调制频率测量的相干过渡辐射，以及用于核心和光晕测量的多个荧光屏幕。将提供这些诊断的概述。
In AWAKE a self-modulated proton bunch drives wakefields in a plasma. Recent experiments successfully demonstrated many aspects of the self-modulation of the drive bunch as well as acceleration of test electrons. Next experiments will focus on producing a multi-GeV accelerated electron bunch with low emittance and low energy spread. The experiment requires a variety of advanced beam diagnostics to characterize the self-modulated proton bunch at the picosecond time scale. These include optical transition radiation and a streak camera for short and long time scale detailed imaging of self-modulation and hosing, coherent transition radiation for modulation frequency measurements in the 100-300 GHz frequency range and multiple fluorescent screens for core and halo measurements. An overview of these diagnostics will be given.
