HGCAL LV cable optimisation Ian 15 April 2019
1. Define LV power requirements, 2. Define a granularity 3. Define an allowable power lose 20- 50% 4. Obtain cable section 5. Obtain other clients needs in the choke point. It fits or not 6. Look at cable cooling. 7. Other cable insulation technologies. 8. Reiterate from 2 and/or 3 9. Mock-up with real cables and check for power loss temp increase This of course does noty factor in the Nos of rack/module space.
