In the morning, after the start-up pf the machine, scan phase-charge and small tuning it was possible to store the beam with the settings from previous day.
The storage was optimize withthe dipole current of 159.9 (best storage up to now). RF cqvity voltqge 20-100 kV.
Work on the orbit correction and BPM.
The the dipole current was tuned to the nominal current 159.3 A with sufficient storage. AT ~18h the RF cavity went down.
To be continued. |
