MedAustron is an ion beam cancer therapy and research centre currently under construction in Wiener Neustadt, Austria. This facility features a synchrotron particle accelerator for light ions. Cosylab is closely working together with MedAustron on the development of a power converter controller (PCC) for the 260 deployed converters. The majority are voltage sources that are regulated in real-time via digital signal processor (DSP) boards. The in-house developed PCC operates the DSP boards remotely, via real-time fiber optic links. A single PCC will control up to 30 power converters that deliver power to magnets used for focusing and steering particle beams. Outputs of all PCCs must be synchronized within a time frame of at most 1 microsecond, which is achieved by integration with the timing system. This pulse-to-pulse modulation machine requires different waveforms for each beam generation cycle. Dead times between cycles must be kept low, therefore the PCC is reconfigured during beam generation. The system is based on a PXI platform from National Instruments running LabVIEW Real-Time. An in-house developed generic real-time optical link connects the PCCs to custom developed front-end devices. These FPGA-based hardware components facilitate integration with different types of power converters. All PCCs are integrated within the SIMATIC WinCC OA SCADA system which coordinates and supervises their operation. This paper describes the overall system architecture, its main components, challenges we faced and the technical solutions.
