Description
The electron-positron Future Circular Collider (FCC-ee) has challenging requirements for beam instrumentation, including the need for thousands of high-resolution beam position monitors (BPMs) presenting low impedance to the circulating beam. This paper details the requirements for the FCC-ee arc BPMs and presents the simulation results of BPM button pickups with various geometries modelled with FCC-ee beam parameters. These simulation results are used to estimate BPM parameters, including impedance and heating. Applying results from bench-marking tests of other BPMs, a suggested geometry and expected performance are presented.
