L-mode to H-mode transition (L-H transition) is generally obtained in diverted plasmas when the additional heating power exceeds a threshold power.Intermediate phase (I-phase,which is usually shown wi
The low frequency Alfven waves excited by the energetic-particle can significantly affect the plasma performance.These instabilities will affect alpha particle transport,inducing the fusion energy los
Propagation characteristic of femtosecond terawatt laser pulses in Air with higher-order Kerr effect (HOKE) is investigated.By invoking an averaged-in-time one-dimensional model derived from the propa
Turbulence behavior has been studied in L-H transition and inter-ELM phase on EAST tokamak using microwave reflectometry.A dithering L-H transition with a limit cycle oscillation (LCO) appearing on Dα
The destabilization of shear Alfvén waves (SAWs) associated with the loss of energetic particles generated by neutral beam injection (NBI) has been observed on several tokamaks [1‐5].Since the parti
本文研究了在1 T 磁场下的EAST(先进实验超导托卡马克)螺旋波等离子体稳态放电实验.两种右旋发散型和右旋盘绕发散型天线置于EAST 中心与纵场平行,由13.56 MHz射频电源激发,在射频电源功率1000 W,纵场为1 T,气压(氦气)为0.05-1 Pa 的条件下成功实现了螺旋波等离子体放电.放电阈值功率较低(<100 W)且射频电源与天线间匹配较好(反射功率为零).
As the neutron and γ-ray yields in high power takamaks,such as HL-2A and EAST,neutron energy and space distribution measurements will play a important role in thermonuclear fusion experiments to provi
The wetting property of water is very important due to its central role in many physics,biological,chemical,and technological systems.Since almost all the wetting processes occur on the surface of sol
