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)The antineutrino flux from spent nuclear fuel (SNF) is an important source of uncertainty when making estimates of a reactor neutrino flux. However, to determine the contribution from SNF, sufficient data is needed such as the amount of spent fuel in the pool, t...

摘要:Abstract(#br)In this article, we evaluated the error field caused by magnetization of a large steel-made optical platform of Phase Contrast Imaging (PCI) diagnostic system on the top of the HL-2A tokamak to make sure the relative magnetic perturbation from the equilibrium is...

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:Abstract(#br)The impact of a low frequency MHD mode crash on triggering the H-mode has been studied in detail on the HL-2A tokamak. The mode manifests fishbone characteristics with a precession frequency f ≈ 14 – 19 kHz . The abrupt mode crash evokes substantial energy relea...

摘要:Abstract(#br)Poloidal symmetric low frequency oscillations at the plasma edge were observed during the low-intermediate-high transitions on the HL-2A tokamak. The limit cycle oscillation (LCO) frequency gradually reduces from 3.0 kHz to 1.5 kHz approaching the H mode. Meanwhile a...

摘要:Abstract(#br)Visible dust particles generated from plasma-facing components (PFCs) and the impact of the dusts on plasma performance as a source of impurities have been studied in the HL-2A tokamak by means of a fast framing camera together with other diagnostics. The camera imag...
