The patented hollow anode structure enables the tube to cope with inverse voltage and current without consequent reduction in its high voltage hold-off capability due to electrode damage. A reservoir normally operated from a separate heater supply is incorporated. The reservoir heater voltage can be adjusted to a value consistent with anode voltage hold-off in order to achieve the fastest rate of rise of current possible from the tube in the circuit. . . 57.15 mm (2.250 inches) min . 152.4 mm (6.000 inches) nom . . . 13 kg (29 pounds) approx 3) . . . . . . . . . any . . . . . . . . see outline Cooling For all applications, cooling by oil or coolant immersion is desirable. Further information is contained in the relevant section of the Preamble. At and below 55 kV the CX1594 may be cooled by forced-air directed mainly onto the base, and the ceramic envelope should be maintained below the maximum rated temperature. An air flow of at least 2.83 m3/min (100 ft3/min), depending on the mechanical layout, will be necessary to keep the tube operating temperatures under the limits specified below. In addition to 300 W of heater power, the tube dissipates from 100 W per ampere average anode current, rising to 300 W/A at the highest rates of rise and fall of anode current. The cathode end of the tube must be cooled whenever heater voltages are applied, since the cathode flange will reach a temperature of 120 8C above ambient in the absence of cooling.
