摘要:The oscillations of poloidal plasma flows induced by radially sheared zonal flows are investigated by newly developed correlation Doppler reflectometers in the HL-2A tokamak. The non-disturbing diagnostic allows one to routinely measure the rotation velocity of turbulence, and he...

摘要:Based on the fact that the scattered power is proportional to the square of the electron density fluctuation amplitude, the four-channel formic acid (HCOOH, λ=432.5 um) laser interferometer has been firstly upgraded to measure the far-forward collective scattering ( F...

摘要:Recent experimental results that are associated with the core-localized (i.e. normalized radius ) Alfvénic modes in HL-2A neutral beam injection (NBI) plasmas with weak magnetic shears are reported. In the different plasma parameter regions, the energetic ions produced by th...

摘要:Understanding of nonlocal electron heat transport is of key importance for current magnetic confinement fusion research. Global nonlocal response presents a fundamental challenge to the standard anomalous transport model based on local microinstabilities and turbulence. Here, we ...

摘要:In HL-2A, the characteristics of the edge plasma instabilities and their effects on the dynamical evolution of the pedestal in H-mode plasmas have been investigated. In the edge pedestal region with steep pressure gradient, a quasi-coherent mode (QCM) has been observed in de...

摘要:An infrared imaging bolometer diagnostic has been upgraded recently to be adapted for the complications of the signal-to-noise ratio arising from the low level of plasma radiation and high reflectivity of low energy photon (<6.2 eV). It utilizes a platinum foil, blackened on both...

摘要:Edge localized mode (ELM) is successfully mitigated by helium and deuterium supersonic molecular beam injections (SMBIs) on HL-2A. During the ELM mitigation by SMBIs, gradients of ion temperature ( T i) and electron density are softened in the pedestal. It has bee...

摘要:A qualitative model which includes three loops of zonal flow vs. turbulence and turbulence vs. pressure gradient is proposed for the experimentally observed two types of limit cycle oscillations (LCOs) and low-intermediate-high (L-I-H) confinement transitions. The experiment...

摘要:A new electron density profile reconstruction procedure based on the PARK-matrix method has been firstly exploited for the multi-chord formic acid (HCOOH, λ=432.5 μm) laser interferometry system on the HL-2A tokamak. According to the geometric coordinates of the magnetic sur...

摘要:Strong resonant and non-resonant internal kink modes (abbreviated as RKs and NRKs, respectively), which are also called resonant and non-resonant fishbones, are observed on HL-2A tokamak with high-power ECRH + ECCD (or ECRH) and ECRH + ECCD+, respectiv...
