Spectral Effects on Fast Wave Core Heating and Current Drive
RF heating and current drive is an essential component in most magnetic fusion devices, including ITER. Recent results obtained with high harmonic fast wave (HHFW) heating and current drive (CD) on NSTX strongly support the hypothesis that the onset of perpendicular fast wave propagation right at or very near the launcher is a primary cause for reduced core heating efficiency at long wavelength...
متن کاملProgress in ITER Heating and Current Drive System
Recent progress in the R&D and the design work of plasma heating and current drive (H&CD) technologies for ITER are described. The H&CD systems are composed of 20 MW electron cyclotron (EC), 20 MW ion cyclotron (IC) and 33 MW negative ion based neutral beam (N-NB) systems, and design and R&D work continues for plasma commissioning. Significant progress in R&D during the preceding two years has ...

متن کاملECRF Experiments for Local Heating and Current Drive in JT-60U
An ECRF program has been started to study the local heating and current drive in JT-60U. The frequency of 110GHz was adopted to couple the fundamental O-mode from low field side with an oblique toroidal injection angle for current drive. Experiments were performed at the injection power of ~1.5 MW by using three gyrotrons, each of which has generated the output power up to ~0.8 MW for 3 seconds...
متن کاملRay-tracing code TRAVIS for ECR heating, EC current drive and ECE diagnostic
A description of the recently developed ray-tracing code TRAVIS is given together with the theoretical background, results of benchmarking and examples of application. The code is written for electron cyclotron studies with emphasis on heating, current drive and ECE diagnostic. The code works with an arbitrary 3D magnetic equilibrium being applicable for both stellarators and tokamaks. The equa...
