Investigation of a superconducting niobium X-band deflecting cavity

Abstract
A 8.665‐GHz deflecting cavity, machined from solid niobium, electron beam welded, chemically polished, anodized and heat treated, yielded a peak magnetic field of 740 G corresponding to a peak electric field of 25 MV/m and a deflecting field of 6.9 MV/m. The maximum Q value was 4.5 × 109. Based on these results, design parameters and suggestions for the fabrication of an X‐band rf beam separator are given.
