Experimental characterization of the edge fluctuations during I-phase at ASDEX Upgrade

Nuclear Fusion
The intermediate phase (I-phase) is a plasma regime that exists at the transition from the low-confinement mode (L-mode) to the fully developed high-confinement mode (H-mode), or vice versa.

Characterization of edge localized modes in tokamak plasmas

, 2012
In the early twentieth century, scientists found out what process keeps the Sun burning: nuclear fusion. At that time, they almost instantly realized that controlling this process could also be a huge potential energy source on Earth. In order to make the fusion reaction (deuterium-tritium) happen, the hydrogen isotopes must be within the mutual ...

Simultaneous ELM suppression and divertor detachment via synergistic boron powder and neon injection in EAST

Nuclear Fusion
A novel approach for simultaneous power exhaust and edge-localized mode (ELM) control is presented in the Experimental Advanced Superconducting Tokamak discharges, which utilize an ITER-like tungsten divertor.

Facilitated core-edge integration through divertor nitrogen seeding in the HL-2A tokamak

Nuclear Fusion
A divertor detachment with sustainable high-performance plasmas has been achieved through divertor nitrogen seeding in the HL-2A tokamak. The closed divertor structure facilitates achieving high divertor neutral pressure due to its efficient particle ...

Characteristics of edge localized mode in JFT-2M H-mode

Characteristics of edge localized mode in JFT-2M H-mode
JFT-2MのHモードプラズマにおいて観測される周辺振動現象の特性について明らかにした。ELMは周辺電子密度に大きな影響を与えるが、電子温度への影響は、セパラトリック面の近傍を除くと少ないことが、ECE測定より明らかとなった。ELMの起きる実験的条件、制御方法を明らかにし、まとめた。まず、重水素プラズマ中では、一般にELMは起きにくいが、密度が低くなると起きる。また、重水素プラズマに比べ、水素プラズマ中ではELMは起きやすい。このELMは加熱入力を増すことにより制御できる。またプラズマ電流をたち下げることにより抑制でき、たち上げることにより、ELMを生成できることが明らかにされた。ELMのMHD特性を磁気プローブ信号の解析により明らかにした。
