Hello everyone,

The main Timing System at DESY, which distributes all timing information to our systems, is right now configured to generate 1Hz trigger signals on Event #16. This is the trigger that is deliver to most detectors/cameras on our site.

DESY is testing a new Gun and wanted to use a slower trigger frequency during this evaluation.

We were not inform in advance about this reconfiguration. After a few colleagues from SPB approach us reporting this problem, we contacted DESY and got the update. We will take steps to make sure that future Timing changes done by DESY are communicated to XFEL ahead of time.
