摘要:The behavior of hydrogen isotopes plasma-driven permeation (PDP) and gas-driven permeation (GDP) through tungsten coated F82H membranes has been studied in the temperature range from 200 °C to 550 °C, using a laboratory-scale steady-state plasma facility. Tungsten coatings h...

摘要:Owing to the character of weakness and complexity, the fault diagnosis of rolling bearing at early stage has turned into a challenging task. As a result, a DS-based adaptive spectrum reconstruction method (DS-ASR) is proposed in this paper to handle the problem. Firstly, multiple...

摘要:The type of edge turbulence transition from resistive ballooning modes (RBM) to drift-type ion temperature gradient (ITG) modes has been observed in the gas puffing modulation experiments and also simulations at the HL-2A tokamak. The experimental evidence on RMB and ITG characte...

摘要:The radial profiles of perpendicular flows in the presence of the magnetic island were firstly measured in the HL-2A tokamak by hopping the work frequency of the Doppler backward scattering reflectometer system along with a two-dimensional electron cyclotron emission imaging dia...

摘要:In HL-2A, an inverse sawtooth oscillation is observed with a long-lasting m / n = 1/1 mode during ECRH phase with power deposition inside sawtooth inversion radius (inner-deposited ECRH), while a normal sawtooth instead appears when the ECRH power is deposited outside sawtoo...

摘要:Dedicated experiments have been carried out at the J-TEXT tokamak for investigating plasma responses to the externally applied resonant magnetic perturbation (RMP) field with various RMP currents under four different toroidal phases. After its penetration, the dominant component ...

摘要:Modulation of turbulent electron temperature fluctuations ( ) and density fluctuations ( ) by an m /n = 1/1 tearing mode island was observed in the core plasma region of the HL-2A tokamak. High spatiotemporal resolution two-dimensional images of show the first evidence that the ...

摘要:Multi-scale interactions have been observed recently in the HL-2A core NBI plasmas, including the synchronous coupling between kink mode and tearing mode, nonlinear couplings of TAE/BAE and TM near surface, AITG/KBM/BAE and kink mode near surface, and between kink mode and...

摘要:A new mechanism of ion cyclotron range of frequency (ICRF)-induced rotation is proposed to explain the toroidal rotation with minority ICRF heating without net momentum injection. For ICRF waves launched with the symmetric spectrum, a nonlinear toroidal force can be generated thr...
