To further the understanding of the r.f. performance of niobium and alternative superconducting materials such as MgB2, high field tests of material samples inserted into host microwave cavities are potentially highly beneficial. In this paper we present results from a detailed design study of such superconducting sample host cavities. The focus of the design work has been on maximizing the ratio of sample surface magnetic field to host cavity maximum surface field, on multiple mode operation to study frequency dependent effects, on mechanical stability of the host cavity under atmospheric pressure, and on choke joints between the sample plates and the host cavity.
