In more detail, the main nodes, the "Plasma" experimental setup itself, and the measurement technique can be described as follows. The gas discharge was excited using a thyratron generator with a TGI1-2000/35 commutator and resonant recharging of a storage capacity of 1650 pF. The high-voltage pulsed power supply unit used in the studies provided a pulse voltage of up to 10 kV, a pulse repetition frequency of no more than 10 kHz, an average discharge current of up to 1 A, and a maximum power deposited in the plasma of up to 2.5 kW. Time-integrated emission characteristics of gas discharges were recorded using a spectrometer built on the basis of the MS 7504i spectral monochromator. The spectrometric complex also included two detectors of optical radiation: the HS 101H CCD line and the R928 photomultiplier. The MS 7504i monochromator is manufactured and designed by SOLAR TII according to the horizontal Czerny-Turner optical scheme with astigmatism compensation. This optical scheme avoids repeated reflection of radiation from diffraction gratings. The spectral composition of the resulting gas-discharge plasma radiation in the wavelength range of 200–1000 nm was investigated. For creating working mixtures based on chalcogen vapors (emitting species - chalcogen molecules, B→X electronic transition) argon or helium at pressures that did not exceed atmospheric pressure were used as buffer gases.
