Research Abstract

Spectroscopy for line intensity ratio from plasma emission only needs relative intensity calibration and is regarded as an useful method to determine the electron density and temperature by combining with the collisional-radiative(CR) model. We have developed an imaging spectrometry technique that uses the wavelength-tunable interference filter based on liquid-crystal technology known as a type of" Lyot filter". Proof-of-principle experiments were conducted for He I spectra in pure helium discharge in the MAP-II(material and plasma) linear divertor simulator at the University of Tokyo. The CR model uses the optical escape factor approximation in dealing with radiation trapping. Moreover, we have improved the prototype spectra camera configuration to yield brighter and more flexible optical arrangement by adopting the optics for macro photography.
