    "abstract": "An improved system for creating a pulsed, low-temperature molecular beam of\nOH radicals has been developed. We use a pulsed discharge to create OH from\nH$_2$O seeded in Xe during a supersonic expansion, where the high-voltage pulse\nduration is significantly shorter than the width of the gas pulse. The pulsed\ndischarge allows for control of the mean speed of the molecular packet as well\nas maintains a low temperature supersonic expansion. A hot filament is placed\nin the source chamber to initiate the discharge for shorter durations and at\nlower voltages, resulting in a translationally and rotationally colder packet\nof OH molecules.",
