Abstract

A detailed analysis of the quadrupole mechanical behavior is presented, which demonstrated that the possibility of delivering well controlled coil pre-compression during assembly, cool-down and excitation. One of the proposed options to increase the LHC luminosity is the replacement of the existing inner triplets at the Interaction Regions with new low-beta larger aperture quadrupoles operating at the same gradient.

Abstract

A study is conducted to examine the several approaches for fabricating multistrand cables in which the Cu is added at cabling, stage of manufacture. The approach include mixed strand Rutherford-type cables with pure Cu strands cabled together with superonductors strands that have a low volume fraction of Cu, Cu added as a core to a Rutherford-type cable, and Cu strip added to the surface of the cable.
