| 3 | High Density Plasma Heating by EC-Waves Injected from the High-Field Side for Mode Conversion to Electron Bernstein Waves in LHD显示文摘To realize an excitation of electron Bernstein waves (EBW) via mode conversion from X-mode waves injected from the high magnetic field side (HFS), new inner-vessel mirrors were installed close to a helical coil in the large helical device (LHD). 77 GHz electron cyclotron (EC) wave beams injected from an existing EC-wave injection system toward the new mirror are reflected on the mirror so that the beams are injected to plasmas from HFS. Evident increases in the electron temperature at the plasma core region and the plasma stored energy were observed by the HFS beam injection to the plasmas with the line-average electron density of 7.5×10 19 m 3 , which is slightly higher than the plasma cut-off density of 77 GHz EC-waves, 7.35×10 19 m 3 . The heating efficiency evaluated from the changes in the time derivative of the plasma stored energy reached ~70%. Although so far it is not clear which is the main cause of the heating effect, the mode-converted EBW or the X-mode wave itself injected from the HFS, an effective heating of high-density plasma over the plasma cut-off of EC-wave was successfully demonstrated. | Y.YOSHIMURA S.KUBO T.SHIMOZUMA H.IGAMI H.TAKAHASHI M.NISHIURA S.OGASAWARA R.MAKINO T.MUTOH H.YAMADA A.KOMORI | 2013 | Plasma Science and Technology2013，15，2： | 0 |
| 4 | Review of Divertor Studies in LHD显示文摘In the Large Helical Device(LHD),two different divertor configurations,i.e.helicaldivertor(HD)and local island divertor(LID),are utilized to control the edge plasma.The HDwith two X-points is an intrinsic divertor for heliotron devices,accompanied with a relatively thickergodic layer outside the confinement region.Edge and divertor plasma behavior from low densityto high density regimes is presented,referring to the divertor detachment.The effect of the ergodiclayer on the edge transport is also discussed.On the other hand,the LID is an advanced divertorconcept which realizes a high pumping efficiency by the combination of an externally inducedmagnetic island and a closed pumping system.Experimental results to confirm the fundamentaldivertor performance of the LID are presented. | T.
