Effect of externally applied resonant magnetic perturbations on resistive tearing modes
Qiming Hu, Q. Yu, Bo Rao +3
Static resonant magnetic perturbations (RMPs) generated by saddle coil current have been applied in J-TEXT tokamak experiments in order to study their effects on tearing mode insta…
Nonlinear modeling of the scaling law for the m/n=3/2 error field penetration threshold
Q. Hu, N. C. Logan, J. -K. Park +3
The scaling law for the n=2 error field (EF) penetration threshold is predicted numerically based on nonlinear single-fluid and two-fluid modeling using the TM1 code. The simulated…
The Role of Edge Resonant Magnetic Perturbations in Edge-Localized-Mode Suppression and Density Pump-out in low-collisionality DIII-D Plasmas
Q. M. Hu, R. Nazikian, B. A. Grierson +3
Two-fluid nonlinear MHD simulations using the TM1 code demonstrate that the formation of magnetic islands at the top and bottom of the H-mode pedestal, together with the strong scr…
Tight focusing proton beam with radius in nanometer scale generation based on channeled solid target
Q. Yu
An efficient scheme of generating ultra-tightly focused proton bunch with radius in nanometer scale is proposed. A needlelike proton filament of transverse size in nanometer scale…
