A Photolysis Lamp for High Intensity, Pulsed Vacuum-Ultraviolet Radiation

Abstract
A low pressure z-pinch flash lamp, employing one capacitor and a single spark gap, is described. With an input energy of 2000 J, the pulse width (τe) of the flash was found to be 1–2 μsec, exhibiting continuous emission down to 125 nm with a maximum at 250±10 nm. This simple lamp thus provides a convenient, routine photolytic source of pulsed vacuum uv radiation that may be employed in conjunction with kinetic spectroscopy.
