Parasitic coupling to the ion Bernstein wave during fast wave heating is investigated using the WIGS computer code. The WIGS code models ion cyclotron range of frequencies (ICRF) antenna coupling to tokamak plasmas for phased coil antenna arrays in a

The paper presents a study of the effects of a simulated L- to H-mode transition for the proposed BPX (Burning Plasma Experiment) device on the coupling of a recessed coil antenna in the ion cyclotron range of frequencies. Two computer codes are used

We study the effects of an L-to H-mode transition in a tokamak on the loading of fast wave launchers in the Ion Cyclotron Range of Frequencies. For analytical simplicity, a dielectric-filled waveguide is chosen for analysis. However, other apertures

One of the key remaining challenges for HPM (> 100 MW, 100 A/cm2 and negligible evidence of cathode plasma. Experimental I-V characteristics of monolithic-metal cathodes suggest anomalously high local surface electric field enhancements (> 100) combi

Proceedings of 1994 IEEE 21st International Conference on Plasma Sciences (ICOPS).
An excimer-laser ({lambda} = 193 nm) produced plasma in an organic gas (TMAE) has been generated and studied. These studies have determined the ion-electron recombination coefficient and the photon absorption cross-section, of the neutral gas. The de
