We have measured the spatial extent of heliumlike and hydrogenlike argon x-ray lines that were emitted from the fuel region of an imploded laser fusion target directly illuminated by the Argus laser. The diameter of the fuel region measured in this way agrees with that obtained from images of the thermonuclear burn region recorded simultaneously by an alpha-particle zone plate camera. Time-averaged electron temperatures in the target core were determined from argon line intensity ratios and compared to ion temperatures determined from measurements of neutron yield.
