Transmission grating based extreme ultraviolet imaging spectrometer for time and space resolved impurity measurements.
نویسندگان
چکیده
A free standing transmission grating based imaging spectrometer in the extreme ultraviolet range has been developed for the National Spherical Torus Experiment (NSTX). The spectrometer operates in a survey mode covering the approximate spectral range from 30 to 700 Å and has a resolving capability of δλ/λ on the order of 3%. Initial results from space resolved impurity measurements from NSTX are described in this paper.

Dual transmission grating based imaging radiometer for tokamak edge and divertor plasmas.
The designs of single transmission grating based extreme ultraviolet (XUV) and vacuum ultraviolet (VUV) imaging spectrometers can be adapted to build an imaging radiometer for simultaneous measurement of both spectral ranges. This paper describes the design of such an imaging radiometer with dual transmission gratings. The radiometer will have an XUV coverage of 20-200 Å with a ∼10 Å resolution...
متن کاملImpurity analysis using a space resolved transmission grating based imaging spectrometer on NSTX
Figure 1: Principle of operation of TGIS. The two slits define a narrow fan beam which is diffracted by the free standing transmission grating. The aperture of the grating determines the spatial resolution of the instrument. Measurement of the impurity content and transport is critical for fusion experiments. The plasma spectroscopy group at the Johns Hopkins University is developing an impurit...
متن کاملDivertor electron temperature and impurity diffusion measurements with a spectrally resolved imaging radiometer.
A divertor imaging radiometer (DIR) diagnostic is being studied to measure spatially and spectrally resolved radiated power P(rad)(λ) in the tokamak divertor. A dual transmission grating design, with extreme ultraviolet (~20-200 Å) and vacuum ultraviolet (~200-2000 Å) gratings placed side-by-side, can produce coarse spectral resolution over a broad wavelength range covering emission from impuri...
متن کاملMultichannel grazing-incidence spectrometer for plasma impurity diagnosis: SPRED.
A compact vacuum ultraviolet spectrometer system has been developed to provide time-resolved impurity spectra from tokamak plasmas. Two interchangeable aberration-corrected toroidal diffraction gratings with flat focal fields provide simultaneous coverage over the ranges 100-1100 A or 160-1700 A. The detector is an intensified self-scanning photodiode array. Spectral resolution is 2 A with the ...
متن کاملCalibration of an extreme-ultraviolet transmission grating spectrometer with synchrotron radiation.
The responsivity of an extreme-ultraviolet transmission grating spectrometer with silicon photodiode detectors was measured with synchrotron radiation. The spectrometer was designed to record the absolute radiation flux in a wavelength bandpass centered at 30 nm. The transmission grating had a period of 200 nm and relatively high efficiencies in the +1 and the -1 diffraction orders that were di...
