	Funding: Supported by the US Department of Energy. The MICE cavities include a mechanical tuning system consisting of stainless steel flexure forks attached to the cavity body and driven by pneumatic actuators. The first of these systems was assembled and tested at Fermilab for use at the MuCool Test Area. The actuators were calibrated on a test hoop. The cavity body was measured and the fork contact pads machined to fit. Actuators were mounted on the vacuum vessel housing the cavity. The transfer function of the tuning system was measured and frequency control software implemented.

	Funding: Supported by the US Department of Energy. The International Muon Ionization Cooling Experiment (MICE) includes two linear accelerator sections with four RF cavities each within a shared vacuum vessel. Ten cavity bodies have been fabricated for MICE including two spares and one was electropolished. A special vacuum vessel was built to house this cavity and form the 201-MHz Single-Cavity Module. The module was assembled, instrumented and tested at Fermilab for installation and operation in the MuCool Test Area.

Automated RF cavity conditioning controls have been implemented in the Fermilab MuCool Test Area using National Instruments LabVIEW. Display of RF paramaters, cavity gradient and diagnostic signals are provided for real-time monitoring. Oscilloscope traces and operating parameters are logged automatically.
