【摘要】 兰州重离子研究装置的磁场测量系统已于1983年10月建立.多探头长臂上装有94个霍尔片.测磁支架采用由长臂、动环和定环组成的以加速器几何中心为原点的极坐标系结构.由小型计算机承担自动控制和数据的获取与处理工作.对16KG磁场,本系统的测量重复性好于±5×10^-5,测量精确度估计为±1×10^-4.测量速度约为每分钟188个数据.更多还原

【Abstract】 HIRFL magnetic field measuring system was built in October,1983.There are 94 Hallprobes on a detecting arm.The positioning device,which mainly consists of a detecting arm,a rotating ring and a fixed ring,is of a polar coordinate type.For 16 KG magnetic field,the measuring repeatability of the system is better than ±5×10^-5,the measuring accuracy isabout ±1×10^-4.The measuring rate is about 188 data per minute.更多还原
