Abstract

The current design for supporting the Collider Quadrupole Magnet (CQM) cold mass utilizes one support which rigidly constrains the cold mass and one support which restrains the cold mass vertically and laterally, allowing axial motion during thermal contraction. The cradle assembly concepts to date have been designed with the Collider Dipole Magnet (CDM) in mind. However, the loading and thermal contraction of the CQM are different from the CDM, therefore, alternate designs have been investigated. Sliding as well as anchored interfaces are considered as options for support of the cold mass. The interaction between the cradle and relevant components (i.e. thermal shields, cryogenic piping, and support posts) have also been considered. Several cold mass support system concepts are presented and the most feasible configuration is determined.
