Description

Electrostatic separator is a crucial component required in the Circular Electron Position Collider to separate electron and positron beams, therefore the two beams can share the RF cavities at high beam operation energies. The impedance contribution from the component is one of the main concerns during the design of the structure. In this paper, the impedance characteristic of the electrostatic separator is investigated. The transverse higher order modes trapped in the component is examined in both simulations and laboratory bench measurements. The mitigation of the trapped modes is also explored.
