8:15 MCC cannot deliver beam with FF on energy on. They called experts
to find out why. While experts are coming, we take dummy runs.
9:50 Bug in beamline located, MCC is making acces to fix it.
10:00 Back to good beam, start kin 4
1:00 Retuning beam to have better energy spread.
3:05 MCC rebooting IOC. No beam at least for 50min.
Dummy runs are at kin 1 at 100uA with raster on, FF on energy is off
