## Feedback status

**Feedback status**

**EPICS ****Collaboration ****Meeting 2004 @ ****RICOTTI, Tokai, JAPAN**

**November, Orbit feedback operation started for user service.**
**-Orbit stability with feedback**
**short term (1 hour)     :  < 1 ********m**
**long term (12 hours)   :  < 3 ********m**
**22 sets of V and H corrector PS are involved for orbit feedback**

**This has been a big issue at PLS, with epics based control system.**
**BPM, PS, ID’s are necessary elements of the feedback operation**
