TI - Wakefield Monitor System for X-Band Lineariser Linac on CLARA J2 - Proc. of LINAC2022, Liverpool, UK, 28 August-02 September 2022 CY - Liverpool, UK T2 - International Linear Accelerator Conference T3 - 31 LA - english AB - 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.
