The requirements for acquiring the electron tube described herein shall consist o
3、f this document and the latest issue of MIL-PRF-1. DESCRIPTION: Square face, two gun, electrostatic deflection and focus. DIMENSIONS AND PIN CONNECTIONS See figure 1. - 11 - 2/ Accelerator power input (average) should be limited to 6 watts. It is recommended that the deflection electrode circuit res
4、istance be approximately equal. Higher resistance values up to 5.0 megohms may be used for low-beam current operation. This tube is designed for optimum performance when operating at an Eb3/Eb2 ratio of 2.0. Operation at other ratios of Eb3iEb2 may result in changes in deflection uniformity, pattern
5、 distornion, and tracking accuracy. All tests except capacitance, vibration, and interaction factor shall be made on each unit separately. Each deflection plate shall be connected to A2 through a resistance of 1 megohm. - 3i - 41 GENERAL: Qualification - Required. AMSC NA 1 of6 DISTRIBUTION STATEMEM

16、a common dc voltage along the 1 D2 axis until the spot of gun A is at +0.719 inch (+18.26 mm) from the geometric center of the tracking area. Then by means of a small correction voltage the spot of gun B shall be moved to the same distance. The spots then shall be moved by means of the common dc vol
17、tage in the opposite direction from the geometric center until the spot of the less sensitive gun reaches -0.719 inch (-18.26 mm). The difference in deflection factor of the more sensitive gun is then compensated for by moving its spot back to -0.71 9 inch (-1 8.26 mm) inch by means of a voltage div
18、ider. This entire procedure is to be duplicated along the 3D4 axis with a distance from the geometric center of f 0.562 inch (f14.29 mm). Then by means of the two common dc voltages the spots shall be tracked over the entire tracking area, a 2.875 inches (73.03 mm) (1 D2) x 2.25 inches (57.15 mm) (3
19、D4) rectangle, and the greatest distance between the spots shall not exceed the limit specified. - 9/ The maximum distance along the vercai or horizontal axis shall not exceed the value specified. - 1 O/ This test to be performed at the conclusion of the holding period. 4 Provided by IHSNot for Resa
