Embodiment Construction

[0036] The present invention will be further described below by means of the accompanying drawings and specific embodiments.

[0037] In the part names of the following devices, the so-called "first", "second" and so on do not represent any logical sequence, but are only used to distinguish the same parts included in the system.

[0038] Such as figure 1 As shown, the structure of the measurement device is divided into a transmitting microwave source 1, a microwave transmitting link, a microwave intrinsic source 8, a microwave intrinsic link, a microwave receiving antenna 12, an orthogonal mode converter 11 and an orthogonal demodulator several parts.

[0039] The microwave transmitting link mainly includes a first power divider 2 connected to the output end of the transmitting microwave source 1, an isolator 3 connected to an output end of the first power divider 2 (the other output end of the first power divider 2 Connected to the first mixer 7, which will be mentioned in ...

Abstract

The invention belongs to the field of nuclear fusion plasma diagnosis, and particularly relates to a Tokamak density fluctuation and electromagnetic field fluctuation correlation measuring device. TheTokamak density fluctuation and electromagnetic field fluctuation correlation measuring device comprises a microwave emitting source and a microwave intrinsic source, and further comprises a microwave emitting link connected with the microwave emitting source, a microwave intrinsic link connected with the microwave intrinsic source, a microwave receiving antenna and an orthogonal mode converter,wherein an angle rotating device is installed on the microwave receiving antenna. By means of the Tokamak density fluctuation and electromagnetic field fluctuation correlation measuring device, strictsimultaneous measurement of plasma density fluctuation and magnetic fluctuation can be achieved, and therefore correlation calculation between local measurement physical quantities is achieved, and the system has the advantages of being high in integration level, easy, convenient and flexible to use, low in cost and easy to maintain.

Description

technical field [0001] The invention belongs to the field of nuclear fusion plasma diagnosis, and in particular relates to a confinement physical parameter measurement device. Background technique [0002] In the experimental research of magnetic confinement controlled nuclear fusion, plasma density fluctuation, electric field fluctuation and magnetic field fluctuation are the key parameters in the research of plasma transport and confinement physics. The correlation between these parameters and abnormal plasma Radial transport is closely related and is closely related to enabling fusion plasmas operating in highly confinement modes. Especially with the continuous improvement of plasma parameters, the research on magnetic turbulence has gradually become a hot spot, and the diagnostic requirements for the measurement of local magnetic fluctuations are also getting higher and higher. [0003] At present, in this research field, local measurements of parameters such as plasma ...
