Abstract : To improve the experimental system to increase the plenum pressure, improve the detection system and speed of data acquisition will require certain additional items. a turbo molecular pump for the vacuum monochromator, a small roots blower to increase the pumping speed of the chamber. In addition, a pulsed laser system, such as a Nd:YAG laser would be usefull to replace the diode lasers. During the past year I have been set up the apparatus for studying rare gas excimer emission from a discharge excited supersonic gas expansion. We have constructed the primary apparatus. This has included the design and construction of a vacuum chamber, several expansion nozzles and gas handling system, external cavity laser diode systems, and the design of interface software. I have completed each individual component of the system. The remaining work is to set up the new monochromator vacuum system and then start acquiring data.
