An X-band RF cryogenic material testing system has been developed in the past few years. This system employs a high-Q copper cavity with an interchangeable flat bottom working under a TE{sub 013} like mode. By measuring the cavity Qs with a network analyzer, the system can characterize the surface resistance of different samples at different temperatures. Using a 50 MW 2{mu}s pulsed klystron, the system can measure the quenching H field for superconducting samples, up to 300-400 mT. In this paper, we will present the most recent developments of the system and testing results.
