The image intensifier in the SQS Exit Slit imager had been exchanged on request of SQS, Thomas Baumann.
Model: Hamamatsu MCP C9546-03-Y001 against C9546-01.
The position of the YAG screen on the camera is slightly shifted which may slightly affect the spectral axis, a few pixels vertically, and approximately |

The SA3 FEL imager is now protected via the Big Brother server, which creates a beam limit on the bunch pattern server if necessary.
contact Andreas Koch, Lars Fröhlich for more details or consult the imager manual, section 2.9:

Beam Downtime
During last night, apparently the photon beam was down in all SASE beamlines during two longer periods:
between 2:48am and 3h23am (35 min) on 14.4.2025
between 5:09am and 6h59am (1 hour 50 min) on 14.4.2025
