15、ecommended that the deflection electrode circuit resistances be approximately equal. 2/ The P19 screen may be permanently damaged if the current density is permitted to rise too high. To prevent burning, minimum beam current densities should be employed. 3/ Marking shall be in accordance with MIL-PR

16、F-1. If any specification requirements waiver has been granted, the product-identification marking shall consist of the tube type-number only. (See figure 1 herein.) 4/ The following additional marking requirement shall apply: A line, of adequately contrasting color to the base-material color, shall

17、 be drawn on the tube base parallel to the tube axis; this line shall be aligned with and on the same side as the index pin. 5/ Although all tests covered herein are required to be performed during preproduction sample approval inspection, the seven tests listed under this caption are performed, nor

18、mally, during preproduction sample approval only. 6/ Beam current shall be measured by applying a sufficient voltage to either D1 or D2 to deflect a 1 by 1-inch (25.4 by 25.4 mm) raster until the raster cannot be seen on the screen. Grid No. 1 bias voltage shall be adjusted so that either D1 or D2 w

19、ill collect 2.5 microamperes. 7/ With the focused spot just above visual cutoff, examine the spot for any abnormalities. The spot shall be of uniform brightness and shall not show any indication of a dual spot. This may be noted as an astigmatic spot of nonuniform brightness, or a spot the extremiti

20、es of which give the appearance of bright cores, with the center of the spot appearing dark. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-PRF-1/1635C 5 TABLE I. Testing and inspection - Continued. 8/ If used, visually check the internal alumin

21、um coating in the area between the edge of the faceplate and internal aquadag; it shall appear uniform and nearly opaque. If not, perform the following test: With a 1.5 by 1.5-inch (38.1 by 38.1 mm) slightly defocused raster, in accordance with method 5221, in the center of the screen, and with Eb2

22、= 10,000 volts, and with a beam current of 15 microamperes, there shall be no evidence of any doubling of the raster lines (venetian-blind effect), or a sawtooth effect at the edges of the raster. (Any doubling of the raster lines shall be intermittent only, giving the appearance of being pulsed.) R

23、epeat on the edges of the screen in the following positions: a. 45 clockwise from the plane of pin No. 1. b. 135 clockwise from the plane of pin No. 1. c. 225 clockwise from the plane of pin No. 1. d. 315 clockwise from the plane of pin No. 1. These tests shall be made quickly to prevent burning of

24、the screen; apply the grid drive momentarily. 9/ The ratio of the line width of a 2-inch (50.8 mm) long trace, adjusted for best center focus, to the line width measured on the faceplate axis when the trace is deflected perpendicularly plus or minus 4 inches (101.6 mm) from the face center by a bala

25、nced dc voltage, shall not be greater than the value specified herein. 10/ Unless otherwise specified, tubes subjected to the following destructive tests are not to be delivered on the contract: Shock; life test.
