4B. Auchmann TE-MSC-MDT
Insulation alternatives Passive compensation of persistent currents Mechanical concepts:
o Integrated pole with new gap control and bending (evolution of TQC and HFD ideas).
o 2-in-1 version with differential contraction between central posts, gap control, bending.
o Pole loading with special care for ends region. Intra-layer heaters

5B. Auchmann TE-MSC-MDT
Tunnel integration: o Heat extraction (more critical for triplet), o Electrical connections in tight space (studied also in HL-
LHC WP 3, Task 2) o Protection systems: what are realistic delays and
thresholds? (currently for nQPS threshold is 800 mV at 3.5 TeV due to electrical perturbations)
o Alignment New conductor generations in PIT an RRP Radiation resistant epoxies (more critical for triplet) Gather more experience with cored cable Study snap back (does it require dedicated
correctors?) Improve analysis capabilities for quench, persistent
currents, …
