Geng, et al., First RF Test at 4.2K of a 200MHz Superconducting Nb-Cu Cavity, in Proceedings of the 2003 Particle Accelerator Conference, Joe Chew, Peter Lucas, and Sara Webber, eds., (IEEE, Piscataway, NJ, 2003), pp. 1309–1311. This is the most recently published paper containing Cornell's experimental results on a 200 MHz single cell prototype for the superconducing cavities we propose here.
• Don Hartill, 200MHz SCRF cavity development, presented at the April 25–26 2005 MUTAC review of the Neutrino Factory and Muon Collider Collaboration. This talk contains the most recent experimental results from Cornell relevant to the 200 MHz superconducting cavities.
• M. Ono et al., Magnetic Field Effects on Superconducting Cavity, in 9th Workshop on RF Superconductivity, Los Alamos National Laboratory report LA-13782-C. This paper is the basis for our hope that we can operate these cavities with a magnetic field of as much as 0.1 T at the cavity surface. Don Hartill's talk above also presents positive results testing the 200~MHz cavity with a magnetic field as high as 0.12 T.
