  56   Fri Apr 1 18:19:58 2022 KristianCalibrationHV dividerWe checked the strange behavior of the HV
dividers again. The Ohmlabs and the PTB divider
are in good agreement at 120 kV and 150 kV.

  107   Wed Apr 6 09:30:53 2022 DanyalAcceleratorESR is blue again - errors are fixedThe ESR is "blue" again. 

The errors (scu related) have been fixed.
  
  106   Wed Apr 6 08:31:54 2022 Danyal & ReginaGeneralESR had some errorsRegina noticed that the ESR was "red" 

This means that there are some errors.
