2. Pohang Accelerator Laboratory POSTECH Outline EPICS Collaboration Meeting 2004 @ RICOTTI, Tokai, JAPAN -Present status of PLS -New project PAL-XFEL -Summary

3. Pohang Accelerator Laboratory POSTECH 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
