October 23, 1997

• Correction of the beam orbit concerned with insertion devices was carried out in the morning.
• An orbit feedback system was tested from the afternoon to the midnight.
• Vacuum conditioning was carried out in the midnight while using the orbit feedback system.
• An integrated stored current of 5.4 A*hrs was gained during 9:00 AM (Oct. 22) and 9:02 AM (Oct. 23). Average beam current was 226 mA during this period.

Beam current (blue line) and beam lifetime (red line) from 9:00 AM, Oct. 23 to 9:00 AM, Oct. 24.
Tuning on the beam orbit and test of the orbit-feedback system were carried out until midnight. Vacuum conditioning was carried out in the midnight.
