Abstract
We report on design changes that have significantly improved the performance of our supersonic jet ultraviolet and vacuum ultraviolet absorption spectrometer. We incorporated the following three features: (1) direct detection of VUV photons rather than scintillator detection; (2) a triple-pass mirror arrangement; and (3) a larger-pathlength monochromator and a finer grating. These upgrades have yielded about an order-of-magnitude improvement in sensitivity and greater than fivefold improvement in resolution.
