Improved the alignment procedure:
Using the pin to make sure of the spatial overlap
SAXS signal is used to make sure
the pin is well centered on the X-ray beam path
YAG is only used in combination with ILM to fix with ~5 um precision the height of the beam
(moving CRLs on laser focus) and the temporal overlap.

Data taken from 11 to cryo failure
Beam conditions stable
Timing scan for different energy
Operation stopped
after cryo failure
Cryo jet was heated up then

Shift summary from Monday 18th 7am until Saturday 7am
MONDAY
Aligned beamline until the beamstop. Macro for recovering mirror positions worked well. Minimal fine
tuning required.
Changed energy to 8.4 keV to align spectrometes on Ni kalpha emission.
Characterized focal spot of the x-rays at |

During the morning shift (7am - 3pm), we couldn't take any meaningful data due to the issue of power glitch which caused the beam permission error
(AIBS) and down of SASE2 Karabo / Online-GPFS due to the lack of cooling in the rack room.
During the late shift (3 pm - 11 pm), after these issues were solved thanks to PRC/DOC/ITDM/EEE at 5 pm..., we could get back in operation relatively |

Summary for sept., 23rd
6:55 SPB just handed the beam over to FXE when the power glitch killed the interlocks and brought down ACC
11:30 After a lot of communication with PRC, Wolfgang Clement and DOC, the beam is back in SA1. We request change to 5.5 keV |

7:00 Power glitch during SPB operation - they were supposed to hand the beam back at 7:30h
Power glitch brought down FXE interlock system with beam stop monitor alarm that could not be reset
SA1 PPL running fine,
seems unaffected
9:10 Beam back in SA1, but still at 7 keV and cannot be changed by BKR to the req'd 5.8 keV, 94 kHz. |
