Dear all,
I just got the information for BKR that due to a failed klystron we had a downtime around 8:40am this morning for about 30 mins.
Operation could be restarted successfully afterwards but with a different energy distribution than before. SASE2 has now reduced pulse energy |

Again: power outage !
As yesterday, at around 7am, power was lost in Schendfeld at SASE3. No beam permission, accelerator in TLD mode.
SASE3 has no power, TS-OCD informed and on the way. BKR informs MKK to check cooling water pumps. |

This has several implications:
- ALL PREVIOUSLY SAVED RY POSITIONS ARE OBSOLETE!
- Ry values seem to have changed by a factor of 1000 |

Mirror positions and beam position on the imagers for 14.8 keV SPB, 2mrad
ATTENTION: the alignment was difficult due to the strong background from SA3 with 500 pulses. For the future, maybe SA3 could reduce to single
pulse during alignment of SA1. This would make the process easier. |
