SLAC's SPEAR3 Booster RF system was recently upgraded where the existing klystron providing RF power to a 5-cell cavity was replaced with a Solid State Amplifier (SSA). The Low Level RF Controls (LLRF) to drive the SSA was provided by a high performance FPGA based system built on SLAC ATCA modules. RF Cavity Tuner Controls were replaced with EtherCAT-based stepper motor controller. New hardware was designed and built for PLC-based Machine Protection System (MPS). Fast digitizers to sample and acquire LLRF signals were implemented in a LinuxRT Server. All of these required new Controls Software implementation. This poster illustrates the Controls associated with each of the above hardware.
