The 4PR1000A is a pulse tetrode intended for use in pulse modulator, pulsed-amplifier, and pulsed-oscillator service. The compact, high vacuum radial-beam tetrode, incorporating a graphite anode and non-emitting grids, is recommended for use in new equipments where high voltage, high current, or high duty factor is encountered.
Cooling of the tube is accomplished by radiation from the anode and by circulation of forced-air through the base and around the envelope. Cooling can be simplified by the use of the SK-510 Air System Socket and the SK-506 Air Chimney.
The 4PR1000A is specially designed for medical MRI applications where high noise immunity and high stability are required.
