Abstract

Two different approaches to spectral line emission profile measurement in the ZT-40M Reversed Field Pinch will be discussed. In the first case, VUV emissions (>> 50 nm) are dispersed by a 1-meter normal incidence spectrometer, then wavelength converted by sodium salycilate. The resultant visible image is magnified and dissected using a series of slits machined in a rotating drum which contains the detector. Resolutions of 0.06 nm and 0.1 ms are achieved. In the second method, visible and near UV light is dispersed in a 1-meter spectrometer which has an ITT Vidissector mounted at the exit plane. In this detector, photoelectrons generated at the photocathode are magnetically swept across a narrow slit, permitting scans over > 10 nm of the spectrum in < 0.1 ms. Spectral resolution of < 0.1 nm is also possible.
