The SA2 XTD1 XGM is current offline since Saturday morning.

Yesterday, Friday, it already started to present communication problems ( https://ttfinfo.desy.de/elog/FileEdit?file=/XFELelog/data/2023/10/10.03_a/2023-03-10T19:06:29-00.xml&xsl=/elogbook/xsl/elog-fileform.xsl&mode=edit )  and today it became clear a Hard drive is broken and need to be exchanged.

Theo M. and Fini J. are preparing to enter tunnel around 13:00. PRC has informed BKR, RC and HXRSS team. We do not expect to have the problem fixed until the end of the Saturday.

In parallel, beam permission to South Branch was removed due to the lack of communication to the XGM. PRC suggested RCs to disable the corresponding Big Brother rule in order to keep beam permission to proceed with few activities until the ZZ takes place, what was done by machine RPO.

*** Update 14:50:

The ZZ was successful and the colleagues managed to exchange the hard drive and reinstall the software. The XGM shall be working again but it will be monitored in the coming hours.

Special thanks to Theo M., Fini J., Soeren G. and Dey-IT colleagues for the precious volunteer work on Saturday.
