Sven, Marcel,

as a side-aspect of the SPECS visit on Thursday, they recommended an
additional, thumb-thick grounding cable between the trARPES chamber and
the ground connector. Right now, the chamber is grounded through the
laser table.

I am not sure about the status of the grounding connectors on the back
side of the clean room. Did we get this additional noise-free ground
already? This application does not need the low-noise ground. Sven, can
you please take care of this additional grounding cable?

Cheers,
  Ralph
