Description
Technical field
This utility model belongs to polychromator field, is specifically related to a kind of polychromator device.
Background technology
Incoherent Plan for Thomson scattering is an important diagnostic method for high-temperature plasma electron temperature measurement.
It can the most directly measure the absolute value of plasma electron temperature.If it is exhausted by Rayleigh scattering or graceful scattering
To calibration, it is also possible to measure the electron density of plasma.The Thomson cross section of electronics is the least, you must use tune Q
Laser instrument thus improve the peak power of incident laser, thus improve the power of scattered light.Generally use electric-optically Q-switched work
Nd:YAG laser instrument, fundamental laser wavelength is 1064nm, laser pulse width about 10ns, and laser peak power can reach
More than 100MW.On HL-2A/2M device, the electron temperature of edge plasma is likely lower than 50eV, and core plasma
Electron temperature could possibly be higher than 15keV.Therefore, we devise the spectral measurement system of such a 7 passage, the survey of scattering spectra
Weight range is 500nm～1060nm, and its electron temperature measurement scope is 10eV～20keV.
Utility model content
The purpose of this utility model there are provided a kind of polychromator device, completes the measurement of scattering spectrum scope to be measured.
The technical solution of the utility model is as follows: a kind of polychromator device, including collimating part and light splitting part, Qi Zhongzhun
Straight part includes a collimating lens, and it is connected above a completely reflecting mirror, and completely reflecting mirror tilts 45 degree of placements to the right, scattering
Light enters from collimating lens, enters spectrum part and divide after collimated lens, and spectrum part divides and includes that spectrum channel, spectrum channel include one
Individual interferometric filter and the detector thereunder installed, detector is provided with collecting lens.
Described spectrum channel has multiple.
Described interferometric filter is tilted to the left 45 degree of placements, and light is often through an interferometric filter, and a part of light is anti-
Penetrate, and detected by detector, and another part is transmitted into next spectrum channel.
Remarkable result of the present utility model is: this polychromator simple in construction, easy for installation, in reducing largely
Continue the usage quantity of lens, thus improves absorbance, decreases optical path length simultaneously, improves the detection to scattered signal
Quality.
