用于电子-正电子束团拾取的高速RF开关电子学
High-speed RF Switch Electronics for picking up of Electron-Positron Beam Bunches
摘要：
束流诊断是保证粒子加速器束流质量的重要环节。在即将建成的北京正负电子对撞机（BEPC II）和环形电子对撞机（CEPC）等现代正负电子对撞机中，电子和正电子都在隧道中运行。为了测量电子束和正电子束，实时拾取这两个不同的聚束是值得关注的。由于相邻的电子和正电子束之间的时间间隔很小，例如，在CEPC中为6 ns，因此需要高速开关电子学。本文介绍了一个高速射频（RF）电子学的原型设计，可以拿起纳秒正电子-电子束团的开关时间小于6 ns。电子和正电子的快速分离是基于RF开关和控制信号的精确延迟调节（~10 ps）来实现的。实验室初步测试表明，该电路能够在6 ns的时间间隔内成功地提取出聚束信号，为进一步实现电子束的测量和束流的定位提供了可能。
英文摘要：
Beam diagnostics is important to guarantee good quality of beam in particle accelerator. Both the electron and positron run in the tunnel in some modern electron positron colliders such as Circular Electron Positron Collider (CEPC) to be built and Beijing Electron Positron Collider II (BEPC II). To measure the electron and positron beams, picking up of these two different bunches in real time is of notable concern. Because the time interval between adjacent electron and positron bunches is quite small, for example, 6 ns in CEPC, high-speed switch electronics is required. This paper presents the prototype design of a high-speed radio frequency (RF) electronics that can pick up nanosecond positron-electron beam bunches with a switching time of less than 6 ns. Fast separation of electron and positron is achieved based on RF switches and precise delay adjustment of the controlling signals (~10 ps). Initial tests have been conducted in the laboratory to evaluate the performance of electronics, the results indicate that this circuit can successfully pick up the bunch signal within a time interval of 6 ns, which makes it possible to further measure the electron and position beams simultaneously.
