High-resolution ($\frac{\Delta \lambda }{\lambda }\approx 0.015$) x-ray spectra in the wavelength region 3.7→6.2 Å (3.4→2.0 keV) have been collected from the Alcator tokamak using a flat crystal Bragg monochromator. Molybdenum $L$ lines and chlorine $K$ lines have been observed and charge-state identifications have been made by comparison with calculations.
