Auxiliary heating and current drive physics for the ST-E1 fusion power plant

Nuclear Fusion
This work describes the physics basis for the proposed auxiliary heating and current drive system on the ST-E1 fusion power plant. The ST-E1 flattop plasma considered here is fully non-inductive with a bootstrap fraction of 0.9 and the remaining current ...

HEAT simulation and IR data comparison for ST40 plasma-facing components

Nuclear Materials and Energy
The Heat Flux Engineering Analysis Toolkit (HEAT) (Looby et al., 2022) was used to simulate the heat flux, qtarget, on ST40 molybdenum divertors. Results were compared with experimental infrared (IR) data.

Ion and electron heating via magnetic reconnection during merging/compression plasma startup in ST40

Nuclear Fusion
Here, we report the latest results on the high-field application of a merging/compression (M/C) plasma startup in the ST40 spherical tokamak, using 96-channel 2D ion Doppler tomography and 30-channel Thomson scattering diagnostics installed over the past

Large Potential Change Induced by Pellet Injection in JIPP T-IIU Tokamak Plasmas

, 1995
"A large, rapid change in the local plasma potential is found to be induced by off-axis hydrogen ice-pellet injection into a tokamak plasma. The polarity of the rapid change is reversed when the pellet is injected into the upper and lower halves of the ...
