AbstraktAbstract
The goal of the first phase of the AWAKE [1,2] experiment at CERN is to measure the self-modulation [3] of the σz=12cm long SPS proton bunch into microbunches after traversing 10m of plasma with a plasma density of npe=7×1014electrons/cm3. The two screen measurement setup [4] is a proton beam diagnostic that can indirectly prove the successful development of the self-modulation of the proton beam by imaging protons that got defocused by the transverse plasma wakefields after passing through the plasma, at two locations downstream the end of the plasma. This article describes the design and realization of the two screen measurement setup integrated in the AWAKE experiment. We discuss the performance and background response of the system based on measurements performed with an unmodulated Gaussian SPS proton bunch during the AWAKE beam commissioning in September and October 2016. We show that the system is fully commissioned and adapted to eventually image the full profile of a self-modulated SPS proton bunch in a single shot measurement during the first phase of the AWAKE experiment.
