SLS 快速轨道反馈 (FOFB) 于 2003 年成功调试[1]。自 2003 年 11 月起，它在 SLS 的用户操作期间运行。考虑到 72 个数字波束位置监视器 (DBPM)，FOFB 以 4 kHz 的速率对 72 个水平 (x) 和 72 个垂直 (y) 校正器应用基于 SVD 的全球轨道校正，而迄今为止使用的慢轨道反馈 (SOFB) 的速率为 0.5 Hz。虽然 SOFB 对于消除由于温度变化和缓慢移动的插入装置 (ID) 间隙引起的轨道漂移非常重要，但 FOFB 还能够抑制因 ID 间隙或磁铁快速变化、地面和梁振动、3 Hz 助推器串扰和电源噪声引起的轨道振荡。本报告介绍了 FOFB 的调试和用户操作的经验。
The SLS Fast Orbit Feedback (FOFB) was successfully commissioned in 2003 [1]. Since November 2003 it runs during user operation of the SLS. Taking into account 72 Digital Beam Position Monitors (DBPMs), the FOFB applies SVD-based global orbit corrections for 72 horizontal (x) and 72 vertical (y) correctors at a rate of 4 kHz, compared to 0.5 Hz for the Slow Orbit Feedback (SOFB) that was used so far. While the SOFB was important for the elimination of orbit drifts due to temperature changes and slowly moving insertion device (ID) gaps, the FOFB is also able to damp orbit oscillations that are caused by fast changes of ID gaps or magnets, by ground and girder vibrations, 3 Hz booster crosstalk and power supply noise. This report presents experience from commissioning and user operation of the FOFB.
