FNAL Main Injector dipole installation equipment

The Main Injector (MI) construction schedule requires the use of several magnet installation vehicles concurrently. During the interval when MI dipoles are to be installed, both existing magnet installation vehicles will be used in the Main Ring (existing accelerator) to support machine operations. This necessitates the development of a new magnet installation system designed for use with the MI dipole magnets. Because all magnet installation vehicles will be available for MI installation following the decommissioning of the Main Ring, the system should be as inexpensive as possible. The chosen solution for MI dipole magnet installation is as follows: a tugger/towmotor (the Tevatron vehicle could be drafted) will tow the Main Injector dipoles to their installation site on dollies, then lift them slightly from the dollies and move them onto their magnet support stands.<
