Abstract :
The pseudospark is a high voltage, low pressure transient discharge of high discharge current and current rise. Several optical diagnostics were used to study the discharge development and to study the different plasma parameters. Laser induced fluorescence, laser absorption spectroscopy, laser tomography measurements on pseudospark switches and fast shutter and streak measurements on the electron beam pseudospark devices are summarized
