TL;DR: In this paper, the authors proposed a non-stressed and pre-curved Be foils to improve the cavity shunt impedance with large beam apertures needed for accommodating large transverse size muon beams.
805 MHz and 201 MHz RF cavity development for MUCOOL
Derun Li,J. Corlett,A. Ladran,R. MacGill,J. Wallig,Michael S. Zisman,Alfred Moretti,A. Rowe,Z. Qian,V. Wu,Robert Rimmer,J. Norem,D. Summers,Yagmur Torun +13 more
TL;DR: In this paper, a pillbox-like geometry with thin Be foils is adopted to terminate the electromagnetic field at the cavity iris, and the possibility of using grids of thin-walled metallic tubes for the termination is also explored.
