An 80 keV, 3.6 MW neutral beam injection system has recently been installed on Doublet III, and the installation of a second system is scheduled within several months. Armor plate consisting of /approximately equals/100 graphite tiles (10 cm x 10 cm) coated with TiC has been plated over portions of the inner vacuum wall lying in the line of sight of the ion sources. In order to monitor the condition of the armor plate an infrared camera and a set of optical pyrometers have been installed alongside the beamline and view the armor plate through a CaF/sub 2/ window. The pyrometers measure the temperature of the armor plate associated with the maximum of the intensity distribution of each ion source.
