一种束流准直方法及其计算机控制程序

A way of beam alignment controlled by a computer program

During beam transport, the beam may be deviated from the center of the beam line axis for a variety of reasons. In order to improve transport efficiency of the beam transport system, it is necessary to align the beam onto the ion-optical-axis of the beam line. This paper introduces an alignment section containing a pair of steering magnets, a quadru-pole and a profile grid. It is simpler, less expensive and more efficient than other ways.
