After successful completion of Run 1 of the Advanced Plasma Wakefield Experiment (AWAKE) at CERN, the experiment started Run 2 in 2021. The goals of AWAKE Run 2 are to accelerate electrons in proton-beam-driven plasma wakefields to high energies with gradients of up to 1 GV/m while preserving the electron beam normalized emittance at the 10 um level, and to demonstrate the acceleration of electrons in scalable plasma sources to 50-100 GeV. The first milestone towards these final goals is to demonstrate electron seeding of the self-modulation of the entire proton bunch. This was achieved in the 2021 run and some highlight results are shown. In the next phases of AWAKE Run 2, a new X-band electron source will provide a 150 MeV, 200 fs, 100 pC electron beam, to be accelerated in the plasma wakefields.

CLARA linear accelerator in phase-2 will utilise an X-band fourth harmonic linac to linearise bunch phase space. Beam induced transverse higher order modes (HOMs) between 15.3 to 16.2GHz will be coupled out through HOM ports, which can be used to correct both position offset and angle misalignment to minimise beam degradation due to HOMs. In this paper we present design of a wakefield monitor system under development, with capability to use either baseband broadband signal for basic alignment, and also carry a detailed narrow-band spectrum analysis on all four (X and Y transverse modes from two couplers) signals. Initial laboratory testing of its subsystem is also presented.
