A planar doubled-sided muffin-tin structure is being studied as a possible candidate for a 120-GHz accelerator structure fabricated using the deep etched x-ray lithography and micromachining technique (LIGA). Thermal analysis has shown that a superconducting cavity using a thin Nb film on a copper structure will lower the power dissipation by several orders of magnitude. In this paper the various relevant parameters of the proposed superconducting cavity, such as the surface impedance, the shunt impedance, the unloaded quality factor, and the unloaded peak power, at very high frequencies, are discussed.
