Abstract
Устройство для генерации импульсных пучков быстрых электронов в воздушном промежутке атмосферного давления, включающее в себя сплошной цилиндрический катод, на который подается импульсный потенциал и заземленный анод в виде тонкой металлической фольги, сквозь который выводится пучок, отличающееся тем, что вокруг всей боковой поверхности катода, а также перекрывая часть межэлектродного промежутка, расположена цилиндрическая кварцевая трубка, имеющая с катодом жесткий механический контакт, при этом межэлектродное расстояние определяется величиной приведенной напряженности электрического поля Е/р-[В/(см атм] (Е - напряженность электрического поля, р - давление газовой среды), а расстояние h от эмитирующей поверхности катода до основания цилиндрической кварцевой трубки, находящегося в межэлектродном промежутке, ограничено неравенством 0<h<A, где А - расстояние, при котором между основанием цилиндрической кварцевой трубки, находящимся в межэлектродном промежутке, и анодом происходит искровой разряд.A device for generating pulsed beams of fast electrons in an air gap of atmospheric pressure, including a continuous cylindrical cathode, to which a pulsed potential and a grounded anode in the form of a thin metal foil are supplied, through which a beam is output, characterized in that around the entire lateral surface of the cathode, and also blocking part of the interelectrode gap, there is a cylindrical quartz tube having a hard mechanical contact with the cathode, while the interelectrode distance is determined is the magnitude of the reduced electric field strength E / p- [V / (cm atm] (E is the electric field strength, p is the pressure of the gas medium), and the distance h from the emitting surface of the cathode to the base of the cylindrical quartz tube located in the interelectrode gap is limited inequality 0 <h <A, where A is the distance at which a spark discharge occurs between the base of a cylindrical quartz tube located in the interelectrode gap and the anode.
