a b s t r a c tIn fusion research the ability to generate and sustain high performance fusion plasmas gains more and more importance. Optimal combinations of magnetic shape, temperature and density profiles as well as the confinement time are identified as advanced regimes. Safe operation in such regimes will be crucial for the success of ITER and later fusion reactors. The operational space, on the other hand, is characterized by nonlinear dependencies between plasma parameters. Various MHD limits must be avoided in order to minimize the risk of a disruption.Sophisticated feedback control schemes help to tackle this challenge. But these in turn require detailed information on plasma state in time to allow proper reaction. Control system and diagnostic systems therefore must establish a symbiotic relationship to carry out such schemes. Today, all major fusion devices implement such a concept.An implementation of such a concept with sustained integration is presented using the example of ASDEX Upgrade. It covers data communication via a real-time network, synchronization mechanisms for data-driven algorithm execution as well as operational aspects and exception handling for failure detection and recovery. A modular distributed software framework offers standardized user algorithm interfaces, automated workflow procedures and the application of various computer and network hardware components. Designed with a special focus on reliability, robustness and flexibility, it is a sound base for exploring ITER-relevant plasma regimes and control strategies.

“…For this reason, FPGA solutions have been in the past limited to specific applications in diagnostics [1,2]. A notable exception is certainly represented by the RIO FPGA architectures [3] (Compact RIO and Flex RIO) which provide an easy FPGA programming and integration via LabVIEW and have been widely adopted for plasma control [4] and other diagnostic applications [5]. This solution, proposed by National Instruments, aims at leveraging the power of FPGA by removing the main barriers in their usage, that is the expertise required in HDL programming and interfacing with the rest of the system.…”

System on Chip is a hardware solution combining different hardware devices in the same chip. In particular, the XILINX Zynq solution, implementing an ARM processor and a configurable FPGA on the same chip, is a candidate technology for a variety of applications of interest in fusion research, where FPGA fast logic must be combined with CPU processing for high-level functions and communication. Developing Zynq based applications requires the development of the FPGA logic using the XILINX Vivado IDE, mapping information between the FPGA device and the processor address space, developing the kernel drivers for interaction with the FPGA device and developing the high level application programs in user space for the supervision and the integration of the system. The paper presents a framework that integrates all the above steps and greatly simplifies the overall process. The framework has been used for the development of a programmable timing device in Wendelstein 7-X. The development of new devices integrating data acquisition and timing functions is also foreseen for RFX-mod.

“…Scientists in the Mirror Forum Group, formed in the fall of 2008, argued that the tandem mirror would lead to a simpler, high-powered neutron source in the near future at modest cost. The system would have real-time control of the mirror-confined plasma [3]. Field-programmable gate-arrays (FPGA) with other advanced hardware/software systems including Graphics Processing Units (GPUs) would be incorporated into the diagnostic suite for near real-time input-output [RIO] control in the steady state mirror magnetic fusion confinement plasma system (http://www.ni.com).…”

Research on controlled nuclear fusion has been largely concentrated on plasma confinement using toroidal magnetic fields. Toroidal systems are complex. A simpler magnetic confinement system may provide a valuable platform for understanding fusion plasmas. The linear mirror machine has delivered good performance with the potential of giving a direct conversion of nuclear energy into electric power. The GAMMA-10 (G-10) linear mirror confinement system at Tsukuba University demonstrated the principle of the direct conversion of plasma energy into electric power on a small scale from the exhaust plasma in the exterior divertor chamber. The tokamak fusion system has to prove that the 10 to 15 MA of plasma current can be sustained continuously with acceptable efficiency. Plasma confinement is due to the magnetic field from the plasma current in tokamaks. There is room for creative new solutions in the magnetic confinement of fusion plasmas, and consideration is given for the alternative approach of using a linear machine with high magnetic mirror fields and the direct conversion of the high temperature escaping plasma to electric power.
