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
