Design and Implementation of a Liquid Nitrogen-Cooled ...

liquid-nitrogen cooled hollow cathode discharge cell was constructed. In broad strokes, this experiment uses a hollow cathode to generate a pulse of hydrogenic plasma containing H+ 3 from an H2 source gas at a variety of para-H2 enrichments. Both the resulting para- and ortho-H+ 3 are then spectroscopically probed using light from a mid-IR
