NSLS II is committed to the use of digital RF controllers for controlling these cavities. Given the number, types and variety of functions of these cavities, we sought to limit the logic development effort by reuse of parameterized code on one hardware platform. Currently we have fielded six controllers in the NSLS II system. There are two controllers each in both the Storage ring and Booster. The first controller in each is used to control the cavity field and the second controller used for diagnostics. In the Linac a controller is provided which modulates the eGUN grid to generate the bunches. Lastly, in the Master Oscillator Distribution System a controller is used to make phase corrections to the outgoing master oscillator clock signal to account for thermal phase drifts along the distribution path.
