The pulsed static deflection spot is one of the very important methods in which the spot measurement can make sure of exactness and reliability. This paper introduces a kind of the pulsed deflection amplifier with much better stability. Its distinguished feature is to supply the pulsed driving current with different duration and flexible amplitude toward the line and frame deflection coils. Thus the deflection coils work at the pulsed static deflection state. The experiments have demonstrated that this kind...

An effective restoration method has been developed, which can be used to eliminate the influence of the shadow mask on the electron spot on the screen of a CRT. Observers can’t get the full information of the beam profile because of the deformed spot. Based on differential theory, a micro stepping method deflects the electron beam linearly and grabs the spot images step by step. And the intact spot image can be restored from the original deformed images. The measurement results indicate that this method is...

An effective restoration method has been developed, which can be used to eliminate the influence of the shadow mask on the electron spot on the screen of a CRT. Observers can’t get the full information of the beam profile because of the deformed spot. Based on differential theory, a micro stepping method deflects the electron beam linearly and grabs the spot images step by step. And the intact spot image can be restored from the original deformed images. The measurement results indicate that this method is accurate enough for designers of electron guns or deflection units to analyze all kinds of experimental tubes.
