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. The first AWAKE run is dedicated to study the Self-Modulation Instability. The two-screen measurement aims to measure the radial proton beam distribution 2m and 10m 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 two-screen measurement results and we give estimates on the strength of the created plasma-wakefields.
