【摘要】 为了测量超导回旋加速器主磁场,设计了一套磁场测量仪控制系统。该系统实现了半径r方向和角度θ方向的运动,并完成对核磁共振仪和数字积分器的实时数据采集。半径方向的定位精度达到10μm,角度方向定位精度达到20 s。测量仪完成一次测量时间只需4 h,已在台架上完成磁场测量全过程的测试,还可应用于其他相关测量领域。更多还原

【Abstract】 In order to measure the magnet field of Superconducting cyclotron,a set of field mapping control system was designed which adopted the method of radius and angel coordinating motion. Data acquisition of digital integral and tesla meter was acquired by control system. The radius location precision was 10 μm,and the angle location precision is 20 second of arc. A total measurement will take four hours and the whole process test had been done on the test stand. The instrument can be applied in other related region.更多还原
