Spool pieces at the SSCL

The basic features of the Superconducting Super Collider lattice are the two beamlines formed by superconducting dipoles (7736) and quadrupoles (1564). The dipoles constrain two 20 TeV proton beams into counterrotating closed orbits of 86.2 Km. The quadrupoles (FODO) require cryogenic cooling to LHE temperatures. This requirement isolates the main magnets from the outside world. The interface required, the Spool, is a crucial component of superconducting lattice design and machine operation. There are over 1588 spools in the Super Collider. The authors present here SSCL spool designs which consist of (1) housing for superconducting closed orbit and multipole correction magnets, (2) cryogenic function, magnet quench protection, system power, and instrumentation interfaces, and (3) cold to warm transitions for warm magnet and warm instrumentation drift spaces
