A dc magnetron discharge in a cylindrical diode with an incandescent cathode, filled with argon at low pressure, was studied by spectroscopic methods. Operating conditions were anode voltage Ua = 0-150 V, magnetic field B = 0-1.2 × 10-1 T, and pressure p = 10-3-10 Pa. It was found that the spectrum consists of ArII, ArIII, and ArIV ion spectral lines. Neutral argon spectral lines (ArI) were not recorded.
