Influence of Position Precision on Work Performance of Streak Tube
装架准确度对条纹管性能参量影响的研究

The trajectory of electron was counted by computer and the data about streak tube was obtained.The MTF about streak tube when various deviations when parts of a tube are assembled,and the image on screen corresponding about the circle figure.The influences on characters of the streak tube such as spatial resolution and image distortion by position errors are discussed in this article,and then a conclusion is made that the deviations from symmetrical axis including angle error and distance error are main factors affecting the spatial resolution and image quality of streak tube.The accuracy of each part of the tube’s manufacturing and installation position should be ensured to improve the work performance of the tube.
