Embodiment Construction

[0011] Such as Figure 4 As shown, a three-dimensional ribbon flow probe system includes a double-combined three-step structure 5-probe group 29 installed on the magnetic drive mechanism of the controlled nuclear fusion research device, and is installed on the controlled nuclear fusion research device. The first three-step structure 6-probe group 30 on the electric scanning gas mechanism, and the second three-step structure 6-probe group 31 installed on the fast pneumatic reciprocating scanning mechanism of the controlled nuclear fusion research device. The 5-probe group 29 with a double-combination three-step structure is composed of two sets of 5-probe groups with a three-step structure arranged up and down, and the pole-wise spacing between the two probe groups is 65 mm. Due to the inherent connection relationship between the various mechanisms in the controlled nuclear fusion research device, the included angle between the first three-step structure 6-probe set 30 and the ...

Abstract

The invention belongs to the technical field of plasma diagnostic, and concretely discloses a three-dimensional zonal current probe system. The invention comprises a 5 probe group, a first 6 probe group and a second 6 probe group, wherein, the 5 probe group arranged on a magnetic transmission mechanism of a controlled nuclear fusion research device has a two-combination three-step structure; the first 6 probe group arranged on an electric scan gas mechanism of the controlled nuclear fusion research device has a three-step structure; the second 6 probe group arranged on a fast pneumatic reciprocating scan mechanism of the controlled nuclear fusion research device has the three-step structure. The invention has the advantage that the probe group adopting the three-step structure can measure the three-dimensional structure and the distribution of various parameters of marginal plasma in radial direction, poleward direction and circumferential direction at the same time. A graphite probe head and a graphite protective sleeve adopt pyrolytic graphite. Metrical data is exact and reliable, and the service life of the probe group is enhanced. The invention can be used for measuring three-dimensional spatial-temporal distribution of the parameters of the marginal plasma in the controlled nuclear fusion research device.

Description

technical field [0001] The invention belongs to the technical field of plasma diagnosis, and in particular relates to an edge plasma parameter measurement system. Background technique [0002] In the tokamak plasma, turbulence can cause abnormal transport, and the nonlinear interaction of turbulence (such as modulation instability, reverse cascade energy process) can generate ribbon flow, and can modulate and reduce the turbulent amplitude and Therefore, ribbon flow plays an important role in modulating and suppressing turbulent flow and transport. In order to study the characteristics of edge zonal flow, it is necessary to measure the edge plasma parameters and their radial distribution. The most commonly used tool at present is the Langmuir (Langmuir) electrostatic probe, which can obtain various information of the edge plasma. However, its spatial resolution is not very ideal, and it can only measure a single independent data, and cannot simultaneously measure the three...
