| 1 | Design and cold test of S-BAND cavity BPM for HLS显示文摘An S-band cavity BPM is designed for a new injector in National Synchrotron Radiation Laboratory. A re-entrant position cavity is tuned to the TM110 mode as position cavity. Cut-through waveguides are used as pickups to suppress the monopole signal. Theoretical resolution of this design is 31 nm. A prototype cavity BPM system is manufactured for off-line cold tests. The wire scanning method is used to calibrate the BPM and estimate the performance of the on-line BPM system. A cross-talk problem has been detected during the cold test. Racetrack cavity BPM design can be used to suppress the cross-talk. With the nonlinear effect being ignored, transform matrix can be used to correct cross-talk. Analysis of cold test results shows that the position resolution of prototype BPM is better than 3 μm. | LUO Qing SUN BaoGen JIA QiKa HE DuoHui FANG Jia | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，S2： | 1 |
| 2 | 一种非正交对称条带束流位置监测器设计显示文摘介绍了一种条带束流位置监测器(BPM)的设计与仿真方法。在国家同步辐射实验室'太赫兹近场高通量材料物性测试系统'工程项目中,针对波荡器出口处真空室非正交对称性的问题,设计了矩形真空室和跑道形真空室下的两种非正交对称性条带BPM,并与传统的圆形真空室下条带BPM进行对比。基于边界元法,利用MATLAB软件分别对三种真空室下的条带BPM进行建模和仿真。仿真结果表明:相对于传统的圆形真空室下条带BPM,矩形和跑道形真空室下条带BPM灵敏度提高了30%,阻抗匹配误差相对降低了20%,束流位置拟合误差降低了80%。考虑加工精度,矩形真空室下的条带BPM更适用于该工程。 | 钱梦翔 吴芳芳 周泽然 周天雨 卢平 孙葆根 | 2020 | 强激光与粒子束2020，32，6： | 0 |
