Transitional evolution of the wave dispersion relation during helicon discharge ignition: an analytical theory from vacuum to steady operation
Lei Chang
The dispersion relations of the helicon and Trivelpiece--Gould (TG) waves in a steady, fully developed magnetised plasma column are well established, but the discharge does not beg…
First reduced model for integrated computations of helicon wave heating and current drive in magnetic fusion plasmas
Zi-Chen Kan, Lei Chang, Zhen-Yu Wang +9
Fast predictive modelling of radio-frequency heating and current drive is important for integrated tokamak scenario design, yet kinetic calculations of helicon-wave absorption rema…
Full-Path Nonlinear Modeling of Microwave Power Transmission Through Ionospheric Plasma for Space Solar Power Station
Pengan Guo, Lei Chang, Yuhan Chen +5
Space Solar Power Station (SSPS) concepts rely on gigawatt-class microwave beams to carry orbital solar energy through the ionosphere, where the beam and the plasma form a coupled…
Fully nonlinear phenomenology of the bump-on-tail (BOT) instability with drag, diffusion and Krook relaxation
Shi-Jie Zhang, Lei Chang, Zhao-Ju Bo +8
Energetic-particle-driven modes in magnetically confined fusion plasmas often exhibit nonlinear frequency sweeping, reflecting complex wave-particle interactions near marginal stab…
