Two-photon laser induced fluorescence measurement of H atom density in %H2–%N2 gas mixture discharges has shown that the flux of H atom remains nearly constant over a wide range of gas compositions and pressures in three types of discharge devices.

Electron excitation temperatures have been measured in a low‐pressure (0.05‐Torr Cs, 2‐Torr total pressure) argon‐cesium discharge that uses a heated cathode (900–1100 K). The excitation temperature determinations are based upon a model tha
