| 1 | Edge and Core Impurity Transport Study With Spectroscopic Instruments in LHD显示文摘杂质运输与能测量杂质的一个维、二维的分布的发达分光镜的仪器在大螺旋状的设备(LHD ) 在边和核心区域被调查。边杂质行为最近用四碳被学习在 CIII (977 Å
) 的不同电离阶段的反响的转变, CIV (1548 Å
) , CV (40.3 Å
) 和 CVI (33.7 Å
) 。什么时候平均线的电子密度, n e , 从 1 ~ 6 ×被增加 10 13 厘米 −3, 比率(CIII+CIV )/n 当时, e 增加比率(CV+CVI )/n e 减少。这里, CIII+CIV (CV+CVI ) 表示 CIII (CV ) 和 CIV (CVI ) 的和紧张。CIII+CIV 显示碳流入, CV+CVI 在各态历经的层通过运输显示排出物。结果因此在在 LHD 由各态历经的层屏蔽的杂质上给试验性的证据,它被三维的边粒子模拟也支持。核心杂质行为也在高密度的分泌物被学习(n e ≤
1 × 10 15 厘米 −3) 与多 H 2-pellets 注射。它被发现 V/D 的比率(V:传送对流速度, D:散开系数) 在小团注射和 Z eff 侧面在价值显示出扁平的 1.1 1.2。这些结果证实没有杂质累积发生在高密度的分泌物。作为结果,铁密度, n Fe , 被分析是 6 × 10 −7(= n Fe /n 数量能甚至在如此的高密度的分泌物作为放射来源可以忽略的 e ) 。从解决空间的 VUV 和 EUV 分光计的一个维、二维的杂质分布最新发展了因为进一步的杂质运输学习也与他们的初步的结果被介绍。 | Shigeru MORITA Motoshi GOTO Masahiro KOBAYASHI Sadatsugu MUTO Malay Bikas CHOWDHURI 董春凤 周航宇 崔正英 Keisuke FUJII Akihiro FURUZAWA Masahiro HASUO AtsushiI WAMAE 揭银先 Mohammed KOUBITI Ikuya SAKURAI Yuzuru TAWARA 万宝年 吴振伟 Naohiro YAMAGUCHI | 2009 | Plasma Science and Technology2009，11，4： | 0 |
| 2 | Spectroscopic Studies on Impurity Transport of Core and Edge Plasmas in LHD显示文摘Spectroscopic diagnostics have been extensively developed for studies of impurityand neutral particle transports at core and edge plasmas in LHD.Diagnostics of core plasmas aresimilar to a tokamak case,i.e.,Z_(eff)from visible bremsstrahlung,K-x-ray measurements from x-ray spectroscopy using Si(Li)detectors and a compact crystal spectrometer,and high-Z impuritydiagnostics from VUV spectroscopy using a flat-field EUV spectrometer.A combination of impu-rity pellet injection and visible bremsstrahlung is an active tool for determination of the diffusioncoefficient D and convective velocity V.Using this tool the spatial structures of D and V areobtained and discussed with a neoclassical effect.On the other hand,the spectroscopic methodfor edge diagnostics is considerably different from the tokamak case because of the existence of athick ergodic layer in addition to the x-points necessarily included into the diagnostic chord view.In order to break this negative situation,Zeeman and polarization spectroscopy are adopted toLHD edge plasmas.As a result,2-dimensional emission contours of HeI and H_α are successfullyobtained.Laser absorption spectroscopy is tried to measure hydrogen neutrals directly.Radialprofiles of edge impurities are also measured with a mirror-assembled 3 m VUV spectrometer.Recent results of and progress in LHD spectroscopy are briefly reviewed. | Shigeru MORITA Motoshi GOTO SadatsuguMUTO Ryuji KATAI Hisamichi YAMAZAKI Hideaki NOZATO AtsuslliI WAMAE Makoto ATAKE Takashi FUJIMOTO Atsushi SAKAUE Hiroaki NISHIMURA Ikuya SAKURAI Chiho MATSUMOTO Akihiro FURUZAWA Yuzuru TAWARA Mitsutoshi ARAMAKI Yuji OKUMURA Koichi SASAKI 龚先祖 李建刚 万宝年 崔正英 | 2006 | Plasma Science and Technology2006，8，1： | 0 |
