串列升级工程质子束流管道系统在加速器南向有三条质子管道,加速器引出的束流先传输到公共质子管道中,在经过一台南向开关磁铁后,被分配到不同的质子管道中。其中南向开关磁铁需将质子束偏转45°、27°;在使用前需进行磁场测量,利用三维平台及Group3测磁仪进行垂直方向上磁场测量。测量结果显示电流值为210 A时,磁铁中心最高磁场可达1.3T。 The tandem upgrade project The proton beam pipe system has three proton pipes south of the accelerator. The beam from the accelerator is first transmitted to a common proton pipe and is distributed to different proton pipes after passing through a south-facing switching magnet. Among them, the south-facing switching magnet needs to deflect the proton beam by 45 ° and 27 °. Before use, it needs to measure the magnetic field and measure the magnetic field in the vertical direction by using the 3D platform and Group3 magnetometer. Measurement results show that when the current value is 210 A, the maximum magnetic field in the center of the magnet can reach 1.3T.
