Abstract

Summary form only given, as follows. A new X-ray imaging crystal spectrometer, which consists of a spherically bent. crystal and a large (10 cm /spl times/ 30 cm) 2D position-sensitive detector, is being installed at the National Spherical Torus Experiment (NSTX). This instrument will record temporally and spatially resolved spectra of helium-like argon from a large number of sightlines through the plasma to measure radial profiles and gradients of the electron temperature, ion temperature, plasma rotation velocity, and ionization equilibrium.
