“…Boltzmann's transport equation was the subject for solution to derive particle energy distributions in (56)(57)(58)(59). Experimental determinations of electron energy distributions were made by (60)(61)(62). References (72)(73)(74)(75) solve the equation and go on to derive swarm parameters in N2 or N2-SF6 mixtures.…”

“…In a dc discharge, the EEDF measurements are technically simpler and have dramatically better sensitivity than in an afterglow plasma since temporal resolution is not required. However, previous probe measurements of the EEDF in the vicinity of the cathode [9], using a cylindrical Langmuir probe, demonstrated that although electrons from the plasma-chemical processes were observable, it could not be used for analytical purposes as the measured EEDF was significantly distorted and the maxima were poorly resolved.…”

A new approach leading to the development of gas analytical detectors is reported. The approach is based on measurements in the near-cathode plasma of fine structures associated with atomic and molecular plasma processes of the high energy portion of the electron energy distribution function (EEDF). A short (without positive column) dc discharge with cold cathode and conducting walls was used. The EEDF measurements in a dc discharge are technically simpler and have dramatically better sensitivity than in the afterglow since temporal resolution is not required. Additional increased probe sensitivity is achieved by using a large-area, larger-radius-of-curvature conducting wall as the probe instead of the more common thin cylindrical Langmuir probe. The wall probe, being almost flat, also greatly reduces the ion current contribution to the measurements. The new approach allows for the development of micro-analytical, dc plasma electron spectroscopy (PLES) gas detectors that are operational up to atmospheric pressure.
