On the reliability oriented optimization of the LHC interconnections
To achieve the maximum beam energy in the LHC the accumulated length of spatial zones, dedicated to the interconnections between the main cryomagnets, has been limited to 3% of the total magnetic length in the Arcs and Dispersion Suppressors. Such a low ratio leads to a very compact design of system...

Sumario: | To achieve the maximum beam energy in the LHC the accumulated length of spatial zones, dedicated to the interconnections between the main cryomagnets, has been limited to 3% of the total magnetic length in the Arcs and Dispersion Suppressors. Such a low ratio leads to a very compact design of systems and subsystems situated in the LHC interconnections. The requirements concerning reliability of the LHC interconnections are very tight since the availability of the collider for physics cannot be compromised. The failure modes taken into account in the LHC interconnections are grouped into 4 categories: material failures, structural failures, fatigue failures and electrical failures. A concept of reliability oriented parametric optimization of the LHC interconnections is presented. (4 refs). |
