Quarter-wave resonators (QWRs) have a vertical asymmetry with respect to the beam axis which causes a deflection of the beam in the vertical plane. An analytic formula for this deflection has been derived by Alberto Facco and Vladimir Zvyagintsev in their paper entitled “Beam steering in superconducting quarter-wave resonators: An analytical approach”. This formula consists of three components which include factors relating to the magnetic and electric field of the cavity, as well as the vertical offset of the cavity with respect to the beam trajectory. Although it has been known for some time that QWRs do indeed induce vertical beam steering, it has yet to be verified through experiment quantitatively. The design for an experiment proposed at ReA3 to systematically measure this deflection and verify the proposed analytic formula will be presented as well as simulation results for the cavities at ReA3.
