Day shift 28.02
Got the beam, aligned it up to the TCC, mirrors in 3 mrad configuration, checked positions for the CRLs. Optimised beam at the HAPG. Beam stability was fine, energy up to 1,5 mJ at 8.2 keV, and up to 1 mJ at 9.1 keV (used for the spectrometer calibration).
Late shift 28.02
Tune back from 9.1 to 8.15 keV, beam was a bit shifted.
Spectrometer calibration and elastic scattering showed very precise beam photon energy.
Night shift 28.02-1.03
Night was dedicated to installation and alignment of CRL4. Start pumping IC1. There were a lot of issues with carabo (HED vacuum scene) DOC is informed.
Day shift 1.03
Continued CRL4 a and b alignment. No big issues, beam is mostly fine, energy is also fine, but sometimes beam stabilization (feedbacks) stops working and observing. |
