摘要： A plasma source mass spectrometer in which ions in a plasma generated in a high pressure (.ltoreq.1 atm) region are introduced into a low pressure (.ltoreq.10.sup.-5 Torr) region to analysis the ion mass includes a moderate pressure (.gtoreq.10.sup.-3 Torr) region which is provided between the high pressure region and the low pressure region. The plasma generated in the high pressure region is diffused to the moderate pressure region in order to produce a diffused plasma. Ions are extracted from the diffused plasma by an ion extraction electrode having an ion extraction opening. In the vicinity of the ion extraction opening a convex-shaped toward the diffused plasma whereby ion sheath is formed, whereby the ions can be extracted toward the low pressure region with a high efficiency.

摘要： A plasma X-ray source is operable, like the plasma focus type source, to generate impulse discharge through a gas filled in a discharge tube. A relatively small amount of the gas is continuously supplied to and evacuated from the discharge tube in accordance with an occurrence frequency of discharge, without operating evacuation and filling of the gas at each cycle of discharge, under the regulation to make constant the pressure within the discharge tube, thereby eliminating the time for exchange of gas contaminated by discharge, reducing the amount of gas used, and improving reproducibility of discharge.

摘要： An anode and a cathode are disposed in an opposing relation in a tubing in which an inactive gas is enclosed to form a discharge lamp by which an atomic spectrum is emitted. The cathode contains atomic spectrum emitting elements also serving to form the material of cathode. The discharge lamp is supplied with a high frequency power from a high frequency source and simultaneously with a direct current power from a direct current source. This causes the direct current discharge and high frequency discharge to be effected between a pair of electrodes in a superimposed manner. The atoms sputtered by the direct current are efficiently excited by the application of the high frequency with the result that atomic spectra with high brightness are obtained.
