or constant laser wavelengths to check the
effects of laser cooling in the Schottky

device

devices
short break, hopefully :)
  
  57   Fri May 14 16:37:01 2021 BenediktGeneralStatus updateRight now, we have to adjust the ion beam
a bit to overlap better with the laser beam.
We keep the laser wavelength at resonance
  
  56   Fri May 14 11:01:33 2021 BenediktCalibrationLaser Beam adjustedThe laser beam was adjusted in his position
to overlap better with the ions.
