100 MeV回旋加速器是串列升级工程的重要组成部分,其束流输运线将质子束流输运至各物理终端,为相关物理实验提供高质量的强流质子束。荧光屏是100 MeV回旋加速器束流输运线束流诊断系统的重要装置,作为束流调试初期的主要观测手段,荧光屏用于在线观测束斑大小,束斑形状和束斑的偏轴位移,进而指导调节束流传输线上的束流电磁光学元件,提高束流传输效率,满足实验对束流品质的要求,同时减少束流损失所引起的辐射本底。调试时,将荧光屏落下,石英玻璃屏处于束流输运线管路的正中心,质子束打到荧光屏的石英玻璃屏上,其反射束反射至观察用摄像
The 100 MeV cyclotron is an important part of the tandem upgrade project. Its beam transport line transports proton beams to various physical terminals, providing a high quality proton beam for the relevant physical experiments. Fluorescent screen is an important device for 100 MeV cyclotron beam transport diagnosis system. As the main observation method in the early stage of beam calibration, the screen is used to observe the beam spot size, beam spot shape and the off-axis displacement of beam spot online, and then guide the adjustment Beam transmission electromagnetic optical components on the transmission line to improve beam transmission efficiency to meet the experimental requirements of the beam quality, while reducing the radiation loss caused by the beam background. Commissioning, the screen will fall, the glass screen in the tethering transport line pipeline center, proton beam hit the screen of the quartz glass screen, the reflected beam reflected to the observation camera
