Dynamic analysis of six-strut supporting system for accelerator magnet
A six-strut magnet support system designed by Lawrence Berkeley Laboratory (LBL) is considered as an alternative to the current SSC magnet support system. The LBL designed a six-strut support system based on the kinematics mount concept that is generally used in the optical and the laser communication industries. The six-strut system is defined by six static degrees of freedom that constrain a point in space with no redundant restraint. Adjustment of any strut's length means redefining the translation or rotational degree of freedom of the mounting point and produces the desirable movement of the magnet system. The accurately operated six-strut mounting system used in the Berkeley's Advance Light Source (AILS) magnet support is able to maintain the magnet system structural integrity to survive a 7 earthquake, position the magnet to high tolerances, have a small footprint, simple to operate, and adjust to a micron level of accuracy. Though finite element simulation has been used for years in safety analysis, such as seismic dynamic response analysis in nuclear reactor and piping supports, in late 1970, it was employed in the dynamic study for a magnet system in Lawrence Berkeley Laboratory in the late eighties. The modeling methodology developed in LBL for the six-strut system desip, especially for the critical mounting joint design under dynamic loads, is presented in this paper and may be employed for prospective SSC accelerator magnet supporting system design.
