摘要: A new probe has been developed to measure the ion velocity distribution function in lowdensity (109-1013 particle/cm3) plasma beams. The can range from small values such as 103 cm/sec 5 X 106 cm/sec. operation of is based on a time-of-flight measurement between fast shutter and an collector. tested pulsed steady-state Nomenclature c = constant describing area entrance hole receiving angle d distance collector e electronic charge f(v) number ions with axial component v h Debye I(t) current k Boltzmann m particle mass; rm for ions, me electrons n density T absolute temperature; Ti Te t — time after U drift velocity, x direction AT7 floating potential Vx, vy, vz components v' expansion front opening
