usesConfiguration
- Cathode made of pure tungsten with a radius of 1 mm in its cylindrical part and a length of 15 mm; truncated conical tip with a vertex angle of 40° and a plateau with a radius of 0.2 mm; hemispherical anode with a flattened top made of graphite; arc ignited in argon at atmospheric pressure; arc current values up to 150 A
- Radially resolved emission spectra; spectral and spatial side-on information about the arc; absolute calibration performed by a tungsten strip lamp placed at the position of the arc
- Spectrograph with a focal length of 0.5 m; triggering controlled by a delay generator with optical outputs via optical fibers; arc imaged by a spherical mirror on the entrance slit of the spectrometer with a width of 30 micrometers
