14、.o Unit Accelerator to final intensifier electrode voltage equally divided over the three intensifier electrodes by 25 megohm resistors connected between each intensifier and the accelerator. It is recommended that the deflection electrode circuit resistances be 1 megohm, or less, and approximately

15、equal, otherwise beam shift at high drives can be expected. Higher resistance values up to 5 megohms may be used for low-beam current operation. This tube is designed for optimum performance when operating at an Eb3/Eb2 ratio of 4.5. Operation at other ratios of Eb3/Eb2 may result in changes in defl

16、ection uniformity and pattern distortion. Accelerator power input (average) shall be limited to 6 watts. ID2 deflection factor shall be within 8 volts of 3D4. The useful scan in the ID2 and 3D4 directions is plus or minus 2 inches (50.8 mm) from tube face center. The ratio of the line width of a 4 i

17、nch (101.6 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 2 inches (50.8 mm) from the face center by a balanced dc voltage, shall not be greater than the value specified. All portions of a ras

18、ter pattern, adjusted so its widest points just touch the sides of a 3.040 inch (77.22 mm) square, will fall within the area bounded by the 3.040 inch (T1.22 mm) square and an inscribed 2.9643 inch (75.18 mm) square. All other electrodes contained within the envelope shall be tied together. This tes
