Coil conversion of the Fermilab 30-inch bubble chamber magnet

Design and construction of the superconducting split solenoid is presented as at the Fermilab 30-inch bubble chamber. The gravity feed pool boiling coils have independent cryogenic/vacuum systems which can move with the iron halves without disconnecting for easier maintenance of the chamber. Magnet parameters are listed in table form. This magnet will replace the existing 8 MW copper coils as part of Fermilab's energy conservation program. Conductor stability and magnet safety are described.
