Energy Deposition Issues
Consider energy deposition issue as an integral part of the magnet design. Need feedback before going too far.
Do we need liner? If yes how big?
Does open midplane magnet design help? If yes, how much?
We considered open midplane in an early days of LHC quad design. However, preliminary energy deposition calculations suggested that the secondary bombardment was also serious. Revisit the issue again.
If open midplane helps then how much do we compromise in gradient (specially if significant number of turns are removed from midplane)?
What is the impact of that on IR design (optics, geometry and magnets)?
