12、leNo reproduction or networking permitted without license from IHS-,-,-MIL-PRF-1/1590F 4 NOTES: 1/ Instantaneous starting is permissible. The maximum permissible instantaneously applied epy is 16 kv and shall not be attained in less than 0.04 second. 2/ In pulsed operation, the peak inverse voltage,
13、 exclusive of a spike of 0.05 s (maximum) duration, shall not exceed 5 kv dc during the first 25 s following the anode pulse. 3/ The driver pulse, measured at tube socket with thyratron grid disconnected, shall have the following characteristics: Amplitude per ratings; tr = 0.35 s (maximum); tp = 2.
14、0 s (minimum); Zg = 250 to 500 ohms. At -55C, 200 V (minimum) shall be required. 4/ The optimum reservoir voltage for operation in accordance with operation (1) conditions shall be 6.3 V ac and shall be held to within 7.5 percent. 5/ A cooling air blast of 10 cubic feet per minute (cfm) may be direc
15、ted into the anode cup when operating at maximum anode dissipation. 6/ Appreciably less jitter than 0.005 s can be realized if the anode voltage is 8.0 kv or more, the grid-drive amplitude is near the maximum and the grid-drive impedance is near minimum. 7/ This test shall be performed according to
16、the life testing schedule given in MIL-PRF-1 paragraph 4.3.8. 8/ There shall be no pronounced resonance in the range from 10 to 2,000 Hz. 9/ The circuit constants shall be chosen under resonant charging conditions so that: epy = 18.0 kv, ib = 180 a (minimum); dtdik= 1,500 a/s (minimum); tp = 1.0 10
17、percent s; prr = 1,000 (minimum). Grid pulse characteristics shall be: tr = 0.35 s (minimum); tp = 2.0 s (maximum); and driver impedance = 500 ohms (minimum). 10/ The tube shall operate satisfactorily on push-button starting within three attempts when the anode voltage (epy) is applied to the tube u
18、nder test in such a manner as to rise from 0 to 16.0 kv (minimum) within 0.03 second. (The filter in the rectifier shall be designed so that the epy reaches at least 7.0 kv within 0.015 second). 11/ The tube shall operate continuously for 10 minutes. 12/ This test shall be performed simultaneously w
19、ith the operation (1) test. An anode delay time measurement shall be made at the end of 2 and 10 minutes of the operation (1) test. The change in anode delay time (with respect to the 2-minute reading) shall not exceed the value specified herein at any time during this test. 13/ The tube shall be te
20、sted by applying a peak forward anode voltage not to exceed that specified in the test conditions for the time jitter test immediately after the cathode warmup period (tk). The variation in firing time (tj), shall be not greater than the amount specified herein after 60 seconds of operation. 14/ The
21、 circuit constants shall be so chosen that the epy = 14.0 kv; ib = 130 a (minimum); dtdik = 1,250 a/s (minimum); tp = 0.4 s 10 percent; prr = 2,500 (minimum). Grid pulse shall be the same as 9/. 15/ This test shall be conducted for a total of 5 consecutive hours with no more than three kickouts and
22、with no evidence of detrimental anode heating. The tube shall be started with Ef = 107.5 percent V ac and operate at this value for 4 hours. At the start of the fifth hour and while the tube is still operating, the filament voltage shall be lowered to Ef = 92.5 percent V ac and remain there for the
23、final hour of operation. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-PRF-1/1590F 5 NOTES: 1. Do not use metal clamp on ceramic envelope. 2. This flange is mechanically and electrically connected to the grid. 3. Recommended anode connected: Li
24、ghtweight spring-clip type (National Co. type 12, or equivalent). 4. The cathode shall be isolated from the base. 5. In certain applications, it may be necessary to extend the anode connector as follows: To replace a 6587 tube type with an 8613, screw the anode adapter marked 6587 firmly into the 86
25、13 anode connector (see figure 1A). To substitute a 8613 tube type for a 5C22, screw the anode adapter marked 5C22 firmly into the 8613 anode connector (see figure 1B). CAUTION: Such substitution may require some equipment modification. FIGURE 1A. Outline drawing of electron tube type 8613. Dimensio
