- Issues with lost of high level controls in the last blue week: not fully understandable why the fiber optics was lost.

SPB:
- Pulse energy during the nights is low; started with 1mJ and later dropped to ~600uJ.

FXE:
- Digitizer problem during the week was solved:
This occurred when a change of bunch number was requested; the digitizers are reconfigure via mid-layer device whenever number of pulses/frequency is updated. 
It is not clear if this was the cause of the issue. DOC reboot the hardware which resume data acquisition. 
Today (Monday) morning FXE noted that another mid-layer device was not displaying digitizer data properly; since the digitizers are the base class, it could be that 
communication was not reinitiated after the hardware reboot. Re-instantiating the mid-layer fix the issue.
- A temperature drift on the Mono is still to be investigated and XRO is aware of it.
