Диагностика пучка эксперименте по плазменному ускорению AWAKE

Beam Diagnostics in the Advanced Plasma Wakefield Experiment AWAKE: https://arxiv.org/abs/2012.10097
A.-M. Bachmann, P. Muggli, AWAKE Collaboration
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.
