摘要: 北京正负电子对撞机直线注入器(BEPCⅡ LINAC)的升级改进要求建立束流光学匹配计算和轨道校正系统，为此对束流光学匹配计算和轨道校正计算的方法进行了研究，并采用VC++语言编写了相应的程序，利用最小二乘法原理进行了束流光学匹配计算，模拟了束流轨道校正，取得了较为理想的结果。Abstract: To meet the requirements of the Beijing electron positron linear accelerator upgrading, the studies on beam optics and orbit correction calculation are carried out. A program for beam optics and orbit correction calculation is developed. By means of least square method, the satisfying results are obtained. The program can actually refect the energy variation along the LINAC. With the program, beam optics parameters can be calculated and beam orbit can be corrected online. And the program will be used on BEPCⅡ LINAC.
