The spectrometer has two conical crystals in the Hall geometry focusing rays from the Kr He$\\alpha$, Ly$\\alpha$, and He$\\beta$ complexes onto a streak camera, with the physics objectives of measuring time-resolved electron density and temperature through observing Stark broadening and the relative intensities of dielectronic satellites.
