    A transversally accelerated high pressure arc launcher is designed to initiate Plasma Induced Lightening Experiment. The fundamental assumptions after a current rise stage of around 10 MA/s are given. From these assumptions, the saturated arc velocity is V s = a d - 1/2 I where a is a constant in the order of 10 -3 [m 3/2/s/A] depending on the detailed geometrical factors. The actual experiment is conducted with a gap separation between 5 mm to 50 mm. The applied current is a crawbarred profile with 1.1 ms sinusoidal current ramp up to 10 kA and decays with a time constant of 6 ms. Good agreement with the model is obtained.
