兰姆位移(Lamb shift)极化离子源结束了实验室台架试验工作,自1987年二季度开始,将离子源搬入HI-13串列加速器大厅。目前为止,去离子水、油冷却系统、高压屏蔽网等辅助装置都已安装完毕,离子源主体也装配就绪,进入调束阶段。自旋进动器(Wien filter)也已加工装配完毕,它是一个电-磁正交场装置,磁极长度为56cm,宽17cm,极间距5cm,激磁强度8k安匝时磁场强度可达0.145T。两对
The Lamb shift polarized ion source ended the lab bench trial and moved the ion source into the HI-13 tandem accelerator lobby beginning in the second quarter of 1987. So far, auxiliary devices such as deionized water, oil cooling system and high-voltage shielding net have been installed. The main body of the ion source is also ready for assembly and enters the tuning phase. The Wien filter has also been machined and assembled. It is an electro-magnetic orthogonal field device with a pole length of 56 cm, a width of 17 cm and a pole pitch of 5 cm. When the excitation strength is 8 kA, the magnetic field strength can reach 0.145 T . Two pairs
