摘要:Abstract(#br)In this article we present the design of a phase contrast imaging (PCI) system on the HL-2A tokamak. This diagnostic is developed to infer line integrated plasma density fluctuations by measuring the phase shift of an expanded CO 2 laser beam passing through mag...

摘要:Abstract(#br)Phase Contrast Imaging (PCI) diagnostic has been developed on HL-2 A tokamak. The chord integral density fluctuations of plasma can be obtained by measuring the phase shift of CO 2 laser which has a wavelength of 10.6 μ m after passing through plasma. The 32-cha...

摘要:Abstract(#br)The main idea of developing Near Infrared Phase Contrast Imaging (NI-PCI) diagnostic on HL-2A tokamak is presented. Compared to the traditional PCI diagnostic which injects CO 2 laser beam with a wavelength of 10.6 μm into plasma, NI-PCI using 1.55 μm laser has ...

摘要:In this article we present the main idea to construct a steady-state upgraded KT-5, with a conductive ring placed in the vacuum chamber center along the axis. It has an externally controllable poloidal magnetic field and a tokamak-like magnetic configuration. Some main parameters...

摘要:Phase contrast imaging (PCI) has recently been developed on HL-2A tokamak. In this article we present the calibration of this diagnostic. This system is to diagnose chord integral density fluctuations by measuring the phase shift of a CO2 laser beam with a wavelen...

摘要:128-channel Beam Emission Spectroscopy (BES) diagnostic basing on neutral beam injection (NBI) has recently been developed on EAST tokamak. It can diagnose plasma density fluctuation with a sample rate of 1 MHz and a spatial resolution of 1–3 cm, according to the diagnosing ...

摘要:The cross phase between radial velocity perturbation and poloidal velocity perturbation plays an important role in the radial distribution of Reynolds stress. Recently, a novel theory of cross-phase dynamics predicts that, depending on the strength of the E × B shearing, the...

摘要:Systematic calibration experiment of Langmuir probe sheath potential coefficient Λ, which is a critical coefficient for estimating plasma sheath potential, has been carried out in the HL-2A tokamak deuterium plasmas. The electron energy probability function (EEPF) shows that...

摘要:Diffraction effects of diagnostic windows and a phase plate are evaluated in sets of phase contrast imaging (PCI) systems on HL-2A tokamak. Results show that wave field of an incident laser with shorter wavelength is less effected by diffraction. The diameter of viewing wind...
