Abstract :
An integrated RF control and data acquisition system has been developed to perform acceptance testing of superconducting RF cavities for CEBAF (Continuous Electron Beam Accelerator Facility). The system provides options for automated resonance locking, VCO frequency and PLL phase optimizations, CW cavity coupling measurements, pulsed RF coupling and Q measurements, and cavity field regulation as well as data logging and retrieval. The system has dynamic range sufficient to stably operate CEBAF SRF cavities at accelerating gradients in the range 0.05-20.0 MV/m and is switchable between six cavity testing positions.<>
