In this shift a number of successful Schottky measurements were done:
With fixed laser wavelength, while varying the wavelength, with different bunching and more (see logfile 1 for more info: line 53 to at least 107).
The detector software sometimes files to change the current of the power supplies, if this happens a simple restart of the GUI fixes the problem.
Once in this shift the Mesytek in the laser lab turned itself (?) off and the background rate increased. Hopefully this was a single event.
