October 17, 1997

Vacuum conditioning (degassing by synchrotron radiation) was carried out all day. Outgassing from the SR absorbers in undulator/wiggler beamlines was also carried out in the midnight.

Beam lifetime and average vacuum pressure at 10:30 AM were 150 minutes and 1.3 nTorr, respectively (beam current:489 mA).

An integrated current of 5.35 A*hrs was gained from 9:22 AM (Oct. 16) and 8:37 AM (Oct. 17). Average beam current was 270 mA.

Beam current and beam lifetime in the morning.
Vacuum conditioning is under way.

Vacuum pressures at 10:27 AM. Beam current ~490 mA, average pressure: 1.36 nTorr.
