摘要： An ion source may include first, second, and third electrodes. The first electrode may be a repeller having a V-shaped groove. The second electrode may be an electron emitter filament disposed adjacent the base of the V-shaped groove. The third electrode may be an anode that defines an enclosed volume with an aperture formed therein adjacent the electron emitter filament. A potential of the first electrode may be less than a potential of the second electrode, and the potential of the second electrode may be less than a potential of the third electrode. A fourth electrode that is disposed between the electron emitter filament and the anode may be used to produce a more collimated electron beam.

摘要： A wind and temperature spectrometer (WTS) may detect the angular and energy distributions of neutral atoms/molecules and ions in two mutually perpendicular planes. The measured energy distribution at a known angle near the peak may be used to infer the full wind vector W. A WTS having a single ion source may be used in conjunction with a crossed small-deflection energy analyzer (SDEA). The crossed SDEA may combine the angular and energy distributions in the two mutually perpendicular planes into a single spectrometer with a single optical axis. A WTS having a single ion source may use less energy and occupy less space than a WTS with two ion sources.
