Vacuum conditioning (outgassing by beams) was carried out while keeping the stored current of 500-400 mA.

We gained an integrated stored current of 10.6 Ampares*hours from 9:06 AM, Oct. 10 to 9:07 AM, Oct. 11. Average stored current during this 24-hours period was 442 mA.

A beam dump happened at 6:07 PM due to an rf trip (not serious).


Beam current from 9:10-11:08 AM. Vacuum conditioning is under way while keeping the stored current of 500-400 mA.


Vacuum pressure in the ring at 11:05 AM. Beam current: 487 mA, average pressure: 3.8E-9 Torr. Vacuum conditioning is under way.
