Dynamics of plasma emission in the gap.

U(peak) = 224 kV, with 150 ps rise time and duration on the half-height about 400 ps.

t [ns] is the time from the process start 

d [mm] is the distance between high-voltage anode (point) and grounded cathode (plate).

ICCD camera gate 500 ps. Red points and lines show the electrode’s location.
