Cable routing plan for protoDUNE

Concerns and questions

• How difficult is it to bring the cables up in the APA frame? How long are the cables? What type of access we need to pass the cables through?

• Are there any mechanical difficulties to pass the cables up the APA frame? Weight? Space?

• 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
