The spectra from magnetron discharges in various gases have been studied with the aim of investigating the efficiency of this type of source in producing the higher states of ionization. The study of helium was of particular interest since in a mass-spectrograph study of this type of discharge made by one of the writers, it was impossible to distinguish the He++ from the H2+ ions which were always present. The discharge between a tungsten filament and a nickel cylinder was operated at widely varying voltages, currents and gas pressures. The most satisfactory results were obtained at about 250 volts, 0.5 ampere and pressure of 0.1 mm of mercury. A magnetic field of the order of 150 oersteds parallel to the axis of the cylinder greatly intensified most of the lines in the region of the spectrum investigated between 7000 and 2000A. Higher members of the series in both the He I and He II spectrum were brought out with good intensity compared to results obtained with other types of discharge. The magnetron should thus be an efficient source of He++ ions. In the case of nitrogen and mercury many lines of the N II, N III, N IV and Hg II spectra were identified.
