cꢎaRacteRistics
The 4CPW1000KA/9009 is a water-cooled power
tetrode intended for use as a pulse modulator or
in pulse regulator service. The tube is rated for
150 kVdc holdoff in a protective atmosphere, with
a 90 amperes pulse cathode curent rating during
conduction and a 1000 kilowatt anode dissipation
rating (average during pulse). Peak anode current
capability in excess of 150 ampers for short pulse
operation is practical.
