电子直线加速器对于脉冲电子束与脉冲微波包络同步的精确性要求是极其严格的。二者之间的任何过大的相对幌动都可能引起电子束能散度的增大,甚至于不能加速电子束。本测量的目的即是对加速器各仪器、各环节的脉冲间隔的相对时间幌动进行测量,以便了解每个环节对总的幌动起多大影响,并为改善该环节的幌动提供必要的测量手段。本 The requirements of the electron linear accelerator for the accuracy of pulsed electron beam and pulse microwave envelope synchronization are extremely strict. Any excessive relative pretense between the two may cause an increase in electron beam energy divergence or even an acceleration of the electron beam. The purpose of this measurement is to measure the relative timing of the pulse intervals of various instruments and stages of the accelerator so as to understand how much each step affects the overall signal and to provide the necessary measurements to improve the timing of this step means. this
