2 / 5 page  CHARACTERISTICS Min Typical Max Critical DC anode voltage for conduction (see note 10) . . . – 0.2 0.3 kV Anode delay time (see notes 10 and 13) .... – 0.15 0.25 ms Anode delay time drift (see notes 10 and 14) .... – 20 50 ns Time jitter (see note 10) .... – 1.0 5.0 ns Recovery time ........ see note 15 and curves Heater and reservoir current (at 6.3 V) ........ 7.5 9.0 10.5 A SINGLE-SHOT OR CROWBAR SERVICE In applications requiring a very rapid rate of rise of anode current, the CX1157 geometry allows it to be mounted in a coaxial structure in order to minimise the total circuit inductance. Operation of the tube under the following ratings results in short anode delay times and very low time jitter. MAXIMUM AND MINIMUM RATINGS (Absolute values) Min Typical Max Anode Peak forward anode voltage (see note 16) ....... – – 20 kV Peak anode current (see note 17) ....... – – 3000 A Average anode current .... – – 300 mA Grid 2 Unloaded grid 2 drive pulse voltage ......... 0.5 1.0 2.0 kV Grid 2 pulse duration ..... 0.25 – 5.0 ms Rate of rise of grid 2 pulse (unloaded) ...... 10 30 – kV/ ms Loaded grid 2 bias voltage . 750 7150 7200 V Forward impedance of grid 2 drive circuit .... 50 50 500 O Grid 1 Grid 1 drive current (DC) . . 50 70 100 mA Heaters Cathode heater voltage .... 5.8 6.8 7.0 V Reservoir heater voltage .... 5.8 6.8 7.0 V CHARACTERISTICS Anode delay time (see note 18) ....... – 30 75 ns Rate of rise of anode current (see notes 18 and 19) .... – 100 – kA/ ms Time jitter (see note 20) .... – 51.0 2.0 ns NOTES 1. The reservoir heater supply must be obtained either from the cathode heater supply or if a separate supply is used it must be decoupled to avoid damage to the reservoir. 2. The tube must be mounted by means of its mounting flange. 3. The maximum permissible peak forward voltage for instantaneous starting is 16 kV and there must be no overshoot. 4. The peak inverse voltage including spike must not exceed 5.0 kV for the first 25 ms after the anode pulse. 5. For single-shot or burst mode applications this parameter can exceed 100 kA/ ms. The ultimate value which can be attained depends to a large extent upon the external circuit. 6. This rate of rise refers to that part of the leading edge of the pulse between 25% and 75% of the pulse amplitude. 7. Measured with respect to cathode. When grid 1 is pulse driven, the last 0.25 ms of the top of the grid 1 pulse must overlap the corresponding first 0.25 ms of the top of the delayed grid 2 pulse. 8. The tube may be operated with a loaded grid 2 bias voltage of 0 to 750 V provided that care is taken to ensure that the peak grid 1 drive current is sufficiently low to prevent triode firing (tube control by the grid 1 pulse). 9. When DC priming is used on grid 1, a negative bias of 100 to 200 V must be applied to grid 2 to ensure anode voltage hold-off. DC priming is especially suitable in crowbar service. 10. Typical figures are obtained on test using conditions of minimum grid drive. Improved performance can be expected by increasing grid drive. Maximum life is obtained with a grid 1 pre-pulse. 11. DC negative bias voltages must not be applied to grid 1. When grid 1 is pulse driven, the potential of grid 1 may vary between 710 and +5 V with respect to cathode potential during the period between the completion of recovery and the commencement of the succeeding grid pulse. 12. To ensure a high standard of ruggedness, all tubes are subjected to the following tests. After each mechanical test all the tubes must then satisfy all electrical tests. (a) Vibration – The tubes are vibrated at 50 Hz with acceleration of 10 g for one minute in the direction of the cathode axis and then in one direction perpendicular to the cathode axis. See note 2. (b) Recovery Time – The tubes are tested for recovery at zero grid 2 bias voltage with a maximum limit of 35 ms. The tubes are subjected to the following tests on a sampling basis. (c) Operation under Vibration – The tubes are vibrated at 10 g in each of three planes at a sweep rate of one octave per minute from 20 to 500 to 20 Hz, under normal operating conditions. See note 2.
