Description
The AWAKE experiment at CERN aims to create GV/m plasma wakefields over a length of 10 m by using a self-modulated 400 GeV/c proton drive beam from the CERN SPS. The first AWAKE run taking place in 2016 and 2017 is dedicated to study the physics and development of the Self-Modulation Instability within the first few meters of plasma. The two screen measurement aims to measure the radial proton beam distribution 2 m and 10 m downstream the end of the plasma to show that protons get defocused in the order of 1 mrad. Measuring maximum defocusing angles in this order requires GV/m radial plasma wakefields, which can only be present if the Self-Modulation Instability developed successfully. We present the first analysis results of the indirect SMI two-screen measurement and we give estimates on the strength of the created plasma-wakefields.
