Ultra-fast development of Ar 2p1−10 relative densities in nanosecond-pulsed barrier discharge in argon

Raw and wavelength-calibrated emission spectra.

Spatial scans of transitions corresponding to the 2p6 and 3p9 upper states.

Raw measurements that were used to determine the number densities of 2p 1-10 and 3p9 states and the calculated number densities.

Raw electrical measurements together with relevant scripts for data processing.
