Recent experiment results from the HL-2A tokamak are presented in this paper. Supersonic molecular beam injection (SMBI) with liquid nitrogen temperature propellant is used. Low SMBI can form hydrogen clusters that penetrate into plasma more deeply and efficiently. Particle diffusion coefficient convection velocity (D = 0.5–1.5 m2 s−1 Vconv < 40 m s−1, respectively) obtained at periphery using modulated SMBI. Multi-probe measurements reveal 0–1, n 0 symmetries of directly measured low...
Significant experimental advances have been made on the HL-2A tokamak along with substantial improvement and development of hardware. A spontaneous particle transport barrier has observed in Ohmic discharges without any external momentum input. The was evidenced by a density perturbation study using modulated supersonic molecular beam injection (SMBI) microwave reflectometry. new features non-local effect induced SMBI analysed. three-dimensional spectral structures low frequency zonal flow,...
Abstract The evolutions of MHD instability behaviors and enhancement both electrostatic electromagnetic turbulence towards the plasma disruption have been clearly observed in HL-2A plasmas. Two types disruptive discharges investigated for similar equilibrium parameters: one with a distinct stage small central temperature collapse ( $$\sim$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mo>∼</mml:mo> </mml:math> 5–10%) around 1 millisecond before thermal quench (TQ), while...
We reveal the branching structure for a nonhomogeneous random walk with bounded jumps. The ladder time $T_1,$ first hitting of $[1,\infty)$ by starting from $0,$ could be expressed in terms multitype process. As an application structure, we prove law large numbers jumps environment and specify explicit invariant density Markov chain “the viewed particles.” limit velocity explicitly environment.
