Description
Technical field
The invention belongs to a kind of nuclear fusion plasma diagnostics field, and in particular to one kind measurement plasma current distribution
With polarized electron cyclotron radiation (ECE) diagnostic system of factor of safety distribution, it has time and spatial resolution height, cost
Low, the advantages that locality is good.
Background technology
The poloidal magnetic field of Tokamak Plasma is produced by plasma current, poloidal magnetic field or factor of safety q=
rBΦ/RBθDistribution be plasma confinement research very important parameter, to analysis plasma transport, magnetic island
Formation, hydromagnetic instability, sawtooth avalanche and the distribution of plasma radial electric field etc. all have great importance.In recent years,
To realize the steady-state operation of the high constraint of plasma, it is proposed that a variety of advanced tokamak operating schemes, for example make plasma
Central current produces cutting cloth with one's hands behind one's back, i.e., corresponding plasma current is in hollow distribution；Another common method is magnetic field
There is more gentle distribution in weak shearing, i.e. core magnetic field configuration, and the value of its factor of safety is maintained near 1 or size 1.These
Operating scheme all plasma current controls propose more strict requirements.
Plasma current control needs CURRENT DISTRIBUTION or the q distributions of accurate measurement plasma.There are 3 kinds of methods at present
CURRENT DISTRIBUTION is measured, they are that internal magnetic configuration is rebuild (EFIT), far infrared polarization interference measurement Faraday rotation and moved respectively
State Stark effect (MSE) diagnoses.EFIT uses outside magnetic measurement information, recycles the inner magnet measurement data weight of plasma
Build the electric current distribution of plasma, the outside magnetic probe signal but this method places one's entire reliance upon, plasma is special
It is the reconstruction of core, error is larger.Faraday rotation and Ac stark effect (MSE) method are used to measure poloidal magnetic field distribution
The angle of pitch, then by inversion integral etc. plasma current distribution and factor of safety q be distributed.Faraday rotation effect one
As use far infrared polar interferometer systematic survey, its general principle is the magneto-optic effect based on electromagnetic wave, when a bunch is inclined
When vibration wave is by with the plasma inside that magnetic field is B, if the angular frequency of ripple is than plasma frequency ωpeAnd electron cyclotron
Frequencies omegaceIt is all much larger, and when wave vector k is parallel to magnetic direction in plasma, then plasma just with the rotation without absorption
Optical medium is similar, and the plane of polarization for the electromagnetic wave that it can make to propagate wherein rotates, and here it is famous Faraday rotation
Effect.If the anglec of rotation of known electronic density and ripple, it is possible to obtain along the magnetic field of measurement string, measure on diverse location string
String integral field, so that it may obtain distribution of the magnetic field intensity in radial direction.But due to this method measurement be magnetic field integration amount, even if
It is the distribution for knowing electron density, also assumes the distribution function in magnetic field, the distribution situation in magnetic field is tried to achieve by function inversion, because
This can introduce larger error.The polarization diagnosis of dynamic Stark is a kind of master to grow up dependent on neutral beam injection technique
Dynamic diagnostic method, the H that it is launched by accurate measurementαThe polarization state of spectrum obtains the information of the magnetic field angle of pitch, is a kind of localization
Measurement.But the broadening of spectral lines as caused by various factors is much larger than the Stark splitting of spectral line, cause serious between different components
It is overlapping, particularly it is difficult to obtain singlet line component under low magnetic field conditions.In addition, can be due in the communication process of polarised light
The factor such as mirror-reflection and window glass introduces extra Faraday rotation and changes the polarization state of light, measurement is caused each
Kind is uncertain.It could be measured in addition, MSE also relies on neutral beam injection condition.Based on above various reasons, MSE polarizations are examined
The disconnected difficulty always generally acknowledged in the world is maximum but is also one of most important diagnosis.Far infrared polar interferometer and dynamically this tower
