OSCILLATION OF ULTRASHORT AVALANCHE ELECTRON BEAM IN INSULATING GAS
Formation of ultrashort (100.2500 ps) avalanche electron beam in insulating gas (SF6) at pressures 0,1...2,5 atm has been studied. Electron beam was obtained at insulating gas pressure in gas diode up to 2 atm behind foil AlBe with thickness of 45 mkm. It was shown that at increased pressures (>1 atm) and supplying high voltage nanosecond pulses ( 270 kV) from generator the pulse duration of utrashort avalanche electron beam at half-height increases up to 150 ps.
