Abstract

The invention belongs to the technical field of nuclear fusion, and particularly relates to a turbulent momentum transport probe array. A rectangular groove at the lower part of a pyrolytic graphite protecting sleeve A is connected with a connecting plate to form a rectangular cavity; a step-shaped cavity fixed connecting piece is arranged at the center of the lower side of the connecting plate; a two-way four-step symmetrical structure is arranged at the upper part of the pyrolytic graphite protecting sleeve A; the middle of the symmetrical structure is high and the two sides of the symmetrical structure are reduced gradually; twenty-one pyrolytic graphite probes are divided into seven rows equally and distributed on steps in parallel; the lower end of each pyrolytic graphite probe is connected with a lead copper tube; the lower ends of the lead copper tubes are collected together by cable leads; the collected cable leads penetrate through a center hole of the connecting plate, and enter the interior of the fixed connecting piece; the lower ends of the cable leads are connected with movable plugs; and insulation sleeves are arranged in the rectangular cavity formed by the pyrolytic graphite protecting sleeve A and the connecting plate, and arranged among the lead copper tubes. With the adoption of the probe array, a macroparameter of plasma of an HL-2A tokamak device can be measured in a discharging process.

Description

technical field [0001] The invention belongs to the technical field of nuclear fusion, and in particular relates to a turbulent flow transport probe array. Background technique [0002] The abnormal transport of particles and energy caused by plasma microturbulence is one of the main difficulties encountered by human beings in the pursuit of magnetic confinement fusion energy. Therefore, the problem of abnormal transport has always been the focus of nuclear fusion research. According to the confinement performance of the tokamak plasma, the properties of the edge plasma play a crucial role in the confinement performance of the overall plasma, and the particle and energy transport processes in the edge region are mainly caused by electrostatic fluctuations. Therefore, understanding the nature and physical mechanism of electrostatic fluctuations in edge plasmas is of great significance for improving the overall confinement performance of plasmas. However, there is still no ef...
