束开关 meaning in Chinese

beam switching

Now we are busy fitting and testing the asipp single - ion microbeam facility . the main work in this paper are as following : testing the performances of bend magnets and magnetic quadruple , simulating the course of beam - line transport , realizing the function of count of the number of radiated ions & control of the electronic beam shutter , calculating different voltage worked on the beam shutter of different beam - line , probing into some factors that may influence the controlling precision and providing some method to solve them
本课题所做的工作主要是对偏转磁铁、磁四极场进行性能测试和对束线的传输进行模拟计算；编程实现离子记数和束开关的控制；计算出使用不同束线时束开关上所应该加上的电压值，并且对可能影响控制精度的因素进行了一些探讨，并提出相应的解决方案。
