Description

The AWAKE experiment relies on the self modulation instability (SMI) of a long (ns) proton bunch in a plasma. The self modulation of the bunch is responsible for resonant driving of the plasma wakefields and the proton bunch develops sub structures with a scale on the order of the plasma wavelength (~1.2 mm in AWAKE) and the square root of the plasma density. Optical Transition Radiation as prompt lightsource and a streak camera are used to image a thin slice of the beam. The resulting time resolved image contains information about the frequency of the self modulation. The remaing spatial dimension contains information about the SMI growth. The diagnostics aims at showing the relation between the SMI frequency and is able to show the complete modulation of the bunch. Experimental results from the first AWAKE runs will be presented.
