In preparation for the upcoming experiments on the Titan laser at the Jupiter Laser Facility, a new Thomson scattering system has been designed and implemented. This system allows electron temperature and density measurements in a high-density regime (n{sub e}>10{sup 21} cm{sup -3}). A 263 nm probe has been demonstrated to produce a total energy of 15 J at 4{omega}(263 nm) in a 1 ns square pulse with a focal spot size of 100 {mu}m. This probe has been used for imaging Thomson scattering of the ion feature. The goal of this study is to investigate the heating of a preformed plasma by a short-pulse heater beam.
