The tunnel in this model of construction is 3-1/2 feet wide by 5 feet high. It is assumed that the tunnel contains a rail system and guidance system for: (1) An enclosed car used for transport of 2 people and some tools. (2) A magnet mover. This robot could pick up a magnet and transport it at about 10 miles per hour. (3) An alignment robot. The alignment robot would intercept E.M. waves (microwaves, lasers) to determine its position in the tunnel. Then workers could come along inside the tunnel hoop and nail it together and to the floor. The trench would then be back-filled with a 1 foot berm on top. A rail system would be installed and a support stand for the magnet.

It has been proposed by R.R. Wilson and L. Lederman that it may be advantageous and cheaper to construct a large accelerator (> 10 TeV) with superferric magnets (approx. 2.5 Tesla). We take as a premise that a sufficiently large piece of land is available for the accelerator (see paper on Site and Tunnel), that is, one is not limited by the radius of the tunnel. The word superferric has been interpreted to mean a super conducting magnet where the coils are used principally to drive the field in the steel. We also add the constraint of simplicity and keep the coil shaped in a rectangle with no more than a few turns.
