Controllability of small size atmospheric pressure plasma generated at low frequency in a pin to dielectric plane electrode configuration was studied. It was shown that the plasma characteristics...
Wave mode conversion and mode transition in very high radio frequency helicon plasma (2006)
Eom, G. S., Kim, Junghee, Choe, Wonho
In a very high radio frequency helicon plasma, experimental evidences for a wave mode conversion between the helicon mode and the Trivelpiece-Gould mode (TG mode) are presented. The helicon mode...
Effect of plasma shaping on performance in the National Spherical Torus Experiment (2006)
Choe, Wonho, Gates, D. A., Maingi, R., Menard, J., Kaye, S., Sabbagh, S. A., ...
The National Spherical Torus Experiment (NSTX) has explored the effects of shaping on plasma performance as determined by many diverse topics including the stability of global magnetohydrodynamic...
