Subject:
Night shift summary 20-21.04.2023
Activities:
Investigated SAXS scattering instability and found it to come from the pointing variation of the PPL
Recorded microscope images of the PPL spot of the pBN to quantify the pointing for different spot sizes
Enlarged the beam and measured pumped SAXS. Results seem better than before.
Problems:
PPL pointing is not stable enough for consistent pumping effect in the probed area.
Sample scanner x motor went into error due to interaction with the magnet and had to be coaxed back into operation.
FEL down with cryo problem.
