Tokamak中的Kelvin-Helmholtz不稳定性

, 1982
Tokamak中的一个重要问题是加热。中性束注入加热是加热的一个有效手段,它使美国PLT上的离子温度达到7.1KeV.但PLT上的中性束注入的不对称性引起等离子体的快速环向旋转,转速可达1×10~7厘米/秒。1979年5月Suckewer等在PLT上测量了速度分布。 在具有速度剪切进行旋转的等离子体中,会不会形成新的磁流体力学不稳定性 ...

Machine learning prediction of plasma behavior from discharge configurations on WEST

Nuclear Fusion
Accurately predicting plasma behavior based on discharge configurations is essential for the safe and efficient operation of tokamak experiments. While physics-based integrated modeling codes provide valuable insights, their high computational cost ...

CRATOS-GS: A free-boundary, hierarchical adaptive mesh refinement Grad–Shafranov solver

AIP Advances
We present CRATOS-GS, a free-boundary hierarchical adaptive mesh refinement (AMR) Grad–Shafranov solver, discretized on Cartesian meshes. The solver is suitable for stand-alone equilibrium calculations, as a foundational component of reduced modeling ...

Runaway dynamics in tokamak disruptions with current relaxation

The safe operation of tokamak reactors requires a reliable modelling capability of disruptions, and in particular the spatio-temporal dynamics of associated runaway electron currents.

Measurement of Internal Magnetic Field with Motional Stark Polarimetry in Current Ramp-Up Experiments of JIPP T-IIU

, 1996
"Multichannel polarization measurements of the Balmer alpha line of beam emission are performed using a 15-channel four-polarizer optical system on the JIPP T-IIU tokamak. The pitch angle of the internal magnetic field is obtained using a newly developed
