Notes:
This article reports the observation of intense x-ray emission by a nonequilibrium energetic electron flow that can be produced when an explosive formed-ferrite filament is used as a plasma initiator in a high vacuum of 10−5–10−3 Torr. Exposure dose measurements and pinhole photographs for the x-ray emission have shown that x rays originate linearly along a 14.5-cm filament with a high exposure dose level of 50 mR(mili-roentgen)/pulse at 6.5 keV, the predominant x-ray energy. The x-ray emission characteristics are described in terms of the time-resolved and -integrated observations in order to infer the x-ray emission mechanism in which an interaction between energetic electron flow and a cloud of ions or neutral atoms thermally produced from the filament has to be taken into account in the close vicinity of the filament.
