电子枪和PDAL之间距离DTA,调正极电位VJ对整管各项性能:偏转灵敏度,分辨力,失真,全管长度影响很大,有利有弊,为了弄清DTA,VJ与上述各项参量的关系,以便得到最佳工作状态,也为了彻底弄清调正电极校正失真的机理,笔者用电子计算机对结构②⑥进行了分析(分别称PDAL(1),PDAL②)。 计算时,PDAL配用7SJ32电子枪(简称GVN(7))合称结构1。
Distance between the electron gun and the PDAL DTA, adjust the positive electrode potential VJ on the performance of the entire tube: deflection sensitivity, resolution, distortion, length of the whole pipe great, there are pros and cons, in order to clarify the DTA, VJ and the above parameters Relationship, in order to get the best working condition, but also to completely clarify the adjustment of the electrode correction distortion mechanism, the author of the electronic structure of the structure ② ⑥ were analyzed (respectively PDAL (1), PDAL ②). Calculation, PDAL equipped with 7SJ32 electron gun (referred to as GVN (7)) collectively referred to as structure 1.
