One of the options for this future accelerator is a Fixed Field alternating gradient Accelerator (FFA). To demonstrate the suitability of FFAs for use in a user facility such as ISIS, there is a plan to construct a smaller scale proof of concept machine: FETS-FFA. Developing beam diagnostics for the FETS-FFA ring presents a challenge due to a large orbit excursion and aperture ( 60 mm x 700 mm). Diagnostics must cover the full size of beam chamber whilst still providing measurement sensitivity and resolution comparable to that seen in the ISIS synchrotron. This paper presents the current design and development of beam diagnostics for the FETS-FFA ring, including finite element studies of Beam Position Monitors (BPMs) and Ionisation Profile Monitors (IPMs).
