Dear all,

Until 2:00am this morning, we were taking data smoothly. At 2:00am, MCC 
started having issues to deliver the 40nA. At 3:00, I was called to 
decide if we keep taking data at 16nA or if we stop everything and call 
the expert without really knowing how long it would take. I chose to 
wait the morning to have a fresh expert and shift crew at MCC.

The beam was stopped at 7:30am so that the expert  could intervene and 
we were back at 8:00am at 40nA. (The problem was apparently related to 
the one we got a few days ago with unstable beam current.)

Plan of the day: Take data at 40nA!

There will be no RC meeting today. Nevertheless, if you have any 
question, do not hesitate to contact me.

Kind regards,

Maxime
