    • An arrangement for the regulation of the electron beam power of an electron gun, which comprises a filament cathode, a block cathode and an anode. Between the filament cathode and the block cathode is applied a first voltage, while between the block cathode and the anode a second voltage is applied. With the aid of a first closed-loop regulated system the filament cathode is regulated to a constant current value, which has a filament temperature sufficient for the maximum beam power of the block cathode. A second closed-loop regulated system, such including a block power regulator, which is acted upon by the difference between instantaneous block power value and nominal block power value, regulates the voltage between the filament cathode and the block cathode.
    • 用于调节电子枪的电子束功率的装置,其包括灯丝阴极,块阴极和阳极。 在灯丝阴极和阻挡阴极之间施加第一电压,而在阻挡阴极和阳极之间施加第二电压。 借助于第一个闭环调节系统,灯丝阴极被调节到恒定电流值,其具有足以使块状阴极的最大光束功率足够的灯丝温度。 第二个闭环调节系统,包括由瞬时阻断功率值和标称功率值之间的差异作用的块功率调节器,调节灯丝阴极和块阴极之间的电压。
