摘要: Abstract Plasma control techniques that use electron cyclotron (EC) resonance heating and current drive such as of neoclassical tearing modes require accurate the deposition location EC beams. ASDEX Upgrade has successfully implemented a real-time version beam-tracing code TORBEAM into its diagnostic system to act globally available module calculates sensitivity from other measurements for all moveable wave launchers. Based on highly (100×) accelerated TORBEAM, software implementation process uses parallelization achieves cycle times 15–20 ms determining radial 12 beams in plasma. This time includes data input–output overhead arising signals. The is by design portable machines ITER.
