The AWAKE project is a proof-of-principle experiment, which aims at accelerating a witness electron bunch in a plasma wake excited by a proton bunch coming from the LHC pre-accelerator, the Super Proton Synchrotron (SPS). Various numerical simulations showed that the charge density within a relatively long (ns-scale) SPS proton bunch experiences a self-modulation instability (SMI) propagating in a plasma and tends to be radially (not longitudinally, no micro-bunches in a common sense) modulated with the plasma oscillation period (on the order of 3-10 ps in AWAKE case). The experimental observation and quantitative analysis of a proton bunch radial density modulation would be an experimental proof of the effective plasma wake excitation. This talk is focused mainly on the various diagnostics that include: Rb vapor density diagnostics, optical transition radiation (OTR) and microwave coherent transition radiation (CTR) setups to measure the SMI frequency, proton beam halo diagnostic to verify the defocused part of a bunch.
