Description
Designing the standard BPM pick-up for the Electron Storage Ring (ESR) of the Electron-Ion Collider (EIC) is a challenging task as the BPM button may experience the elevated beam-induced resistive wall heating due to shorter rms bunch length (~ 7 mm) and high repetition rate. In addition, the BPM pick-up needs to provide reliable beam position measurements over a wide range of beam energies: 5 GeV – 18 GeV. Furthermore, the geometric impedance and the higher order modes associated with the button and its configuration should be analyzed. This paper focuses on the design of the EIC ESR BPM pick-up and presents the corresponding beam-induced heating and thermal analysis. Our analysis shows that active water cooling is required for the ESR BPM.
