The ignition phase and the transition to quasi dc glow operation of a narrow-gap near atmospheric pressure discharge in hydrogen are investigated experimentally. The discharge is ignited by a short 10 ns voltage pulse with a peak voltage of 1.3 kV followed by a 150 ns plateau of about 350 V. Pulsing is at 12 kHz which leaves a significant amount of residual charge between the individual pulses. Temporally resolved laser electric field measurement in the centre of the discharge employing a non-linear four-wave mixing scheme, ultra-high speed optical imaging by an ICCD camera at Balmer-alpha and Fulcher lines as well as the undispersed emission, and current and voltage measurements are performed. Special emphasis is put on a detailed analysis of the measured data by combining the results from the various diagnostics. This allows in addition to the directly measured quantities determination of the absolute evolution of the electron density, the development of space charge shielding, and the observation of the local electron dynamics. Pressure variations in a limited range indicate reasonable agreement with the Paschen law but also raise questions on the definition of the breakdown voltage under highly transient conditions.
