The cathode is made of pure tungsten and has a radius of 1 mm in its cylindrical part and a length of 15 mm. The truncated conical
\ntip has a vertex angle of 40\u00b0 and a plateau with a radius of 0.2 mm. The anode is hemispherical with a flattened top and made of graphite. The arc is ignited in argon at atmopsheric pressure. Arc current values go up to 150 A.
Thermal plasma in the state of LTE except in the regions close to the electrodes.

The triggering is controlled by a delay generator BNC Model 575 with optical outputs via optical fibers. The image of the arc is recorded by a high-speed video camera of the type IDT Motion Pro Y6. The arc is imaged by a spherical mirror on the entrance slit of the spectrometer with a width of 30 micrometers.
