  • Grounding and Shiedling: Can we bundle the cables together? Do we need mechanical/electrical separations in the APA frame?
  • If we go along the cryostat wall, we need longer cables. What is the impact of longer cables on readout? Procurement?
  • Is there anyway we can attached the cables on the cryostat wall? At the moment there is no mechanical
