For instantaneous starting applications where anode voltage is applied instantaneously the maximum permissible epy is 13.5 kv and shall not be attained

14、 in less than 0.04 second. 2. In pulsed operation, the peak inverse voltage, exclusive of a spike of 0.05 s maximum duration, shall not exceed 5.0 kv during the first 25 s after the pulse. 3. Driver pulse measured at tube socket with thyratron grid disconnected shall be egy = 200 v minimum; time of

15、rise = 0.5 s maximum; grid pulse duration = 2 s minimum; impedance of driver circuit = 500 ohms maximum. 4. There shall be no pronounced resonance in the specified frequency range. 5. Use clamp as specified on Drawing 243-JAN. 6. The anode circuit constants shall be chosen so that at epy = 16.0 unde

16、r resonant charging conditions: dik/dt = 1,500 a/s minimum; ib = 175 a; tp = 1.0 s 10 percent; prr = 1,000. The grid pulse characteristic shall be tp = 2.0 s maximum; tr = 0.5 s minimum. Internal impedance of driver = 500 ohms minimum. 7. The tube shall operate continuously without evidence of arc-b

17、ack. 8. Push-button starting shall be attempted up to three times, with intervals of from 10 to 30 seconds between successive attempts. Any tube failing to operate satisfactorily when the anode voltage (epy) applied rises from 0 to 13.5 kv within 0.03 second (the filter in the rectifier shall be des

18、igned so that the epy reaches at least 7 kv within 0.015 second) will be considered a failure. 9. During the interval between 2 minutes and 7 minutes of the anode delay time test, the change in anode delay time (tad) relative to the tad value observed on the anode delay time test shall not exceed th

19、e specified value. 10. Anode heating shall not be cause for rejection on operation (1) and operation (1A) performed during life-test end point test. 11. This test shall be performed during the initial production and once each succeeding 12-calendar months in which there is production. A regular doub

20、le sampling plan shall be used, with the first sample of three tubes with an acceptance number of zero, and a second sample of three tubes with a combined acceptance number of one. In the event of failure, the test will be made as a part of conformance inspection, part 2, code level D, with an accep

21、tance level of 6.5. The regular “12-calendar month” double sampling plan shall be reinstated after three consecutive samples have been accepted. 12. Reclaimed materials shall be utilized to the maximum extent possible. 13. This specification sheet uses accept on zero defect sampling in accordance wi
