  • An X-ray tube target current stabilizer
    The stabilizer shown in the figure was accordingly devised to permit sampling the beam current actually reaching the target at + 4 kV and applying an appropriate signal to the emission circuit at near earth potential.
  • A method of completely filling capillary tubes with mercury for diameter determination
    The stabilizer shown in the figure was accordingly devised to permit sampling the beam current actually reaching the target at + 4 kV and applying an appropriate signal to the emission circuit at near earth potential.

    A circuit is described in wlhichl the series stabilizer tube is inductively coupled to the error amplifier. An output of 20 ina at 4 kv can be psrovided.
  • A simple high-voltage electron microscope voltage stabiliser using current-regulated corona tubes
    The chain of 35 series-connected stabiliser assemblies has a total capacitive reactance of about 4 MO at 10kHz. As the internal resistance of the Cockcroft-Walton . circuit (and the oscillator) has been determined to be about 380 MO at 800 kV and depends slightly on the oscillator setting, the resulting ripple at the electron gun amounts to 2.5 ppm. .

    The noted disadvantages of electronic stabilizers appear to a far lesser extent in circuits of electronic filters which have in their negative feedback loops an alternating voltage amplifier, and react only to variations of the alternating component of the out- put voltage. Thus, for instance, if one utilizes an elec- tronic stabilizer in a rectifier having a voltage of 4 kv and a load current of 200 ma, then the anode voltage of the regulating tube would vary from 200 to 1000 v, and …
  • A 30 MW m-2 electron bombardment heater for heat transfer studies
    The high voltage applied between anode and cathode was supplied from a continuously variable three-phase full-wave rectified supply capable of delivering up to 4 A at 25 kV . Overload protection and safety interlocks were incorporated in the high-voltage circuit . An emission stabilizer was fitted whereby a set emission current wasmaintained by automaticadjustment of the cathode heating …
