Abstract
In a pulsed electron beam source based on the vacuum principle, comprising a vacuum diode having a multi-point emission cathode with a flange and a plurality of emission points, a control grid, a pulse generator, a magnetic compression unit consisting of field coils, a drift chamber, a target chamber and a synchronization unit, the multipoint emission cathode is embedded in a shield electrode, and the shield electrode is connected to the cathode base by way of a resistor which is so sized that the shield electrode is capable of freely floating.
