The 4CPW1000KB is a water cooled power tet-

rode intended for use as a pulse modulator or

pulse regulator. The tube is rated for 175 kVdc

holdoff in a protective atmosphere, with a 75 am-

pere pulse cathode current rating during conduc-

tion and 1000 kilowatt anode dissipation rating

(average during the pulse). Peak anode current

capability in excess of 100 amperes for short pulse

operation is practical.
