  120   Thu Apr 7 01:19:05 2022 PatrickLaserLaser scanningWe did some laser scans. The wavemeter shows
spikes during scans. This may be just while
the frequency changes. See picture.

  231   Thu Apr 14 19:46:46 2022 Sarper & Konstantin & RodolfoLaserLaser powerWe checked the laser power before starting
the new scan range.
  
  83   Sun Apr 3 18:52:30 2022 KonstantinCalibrationLaser ion beam overlapWe measured vertical and horizontal ion beam
positions. Unfortunately, the horizontal
scraper positions can not be manipulated
