“…Also the same magnetic measurement drive system, shaft and probe were utilized, with a custom stand-off to mount it above the top plate. The slow scan rack for monitoring temperature and current history was newly assembled, and is based upon a new compactRio architecture controlled by Labview running on a Windows PC, which was recently developed for the Fermilab Solenoid Test Facility [6].…”

A superconducting quadrupole magnet with splittable yoke has been designed for use in ILC Main Linac (ML) cryomodules. The splittable yoke allows assembly around the beam pipe, to avoid potential contamination of the superconducting RF cavities. The magnet is cooled by conduction and covers the full range of required ML field gradients. A critical requirement is stability of the magnetic center, at the level of 5 microns, for a 20% variation of the operating field. We report here the results of thermal, quench, and magnetic performance tests of a prototype splittable quadrupole, that were made up to the maximum design operating gradient in a conduction-cooled test cryostat.

“…A new facility (SolTF) for testing large aperture conduction-cooled solenoids has been under development at Fermilab [5], and is currently at the stage of cryogenic and power system commissioning. The need for such a facility was recognized several years ago as a rise in the development of large solenoids for high energy accelerator (MICE) and particle physics (Mu2e) experiments was foreseen.…”

Large aperture superconducting solenoid magnets are needed for the production and capture of pions, which decay to create intense muon beams in future experiments to search for direct muon to electron conversion. The COMET experiment in Japan, and the Mu2e experiment in the U.S. are jointly conducting research into the design of capture solenoid coils made from aluminum-stabilized NbTi superconductor that is cooled by conduction to a supply of liquid helium. A prototype coil of 1.3 m inner diameter, having 4 layers of 8 turns each, has been wound with pure aluminum interlayer fins for the conduction cooling. The test coil includes two types of welded splices, two film heaters for quench studies, and extensive instrumentation to evaluate strain, temperature profiles, and coil voltages. Details of the cryogenic conduction cooling scheme, test systems design, and test program plans will be discussed.

“…The recent SS magnet tests were performed at the Wang, NMR fabrication site using a quench detection and data logging system developed at Fermilab [4], which will also be used for operating the SS magnets at RAL. This quench protection system was replicated for testing of large conduction cooled superconducting magnets in a new Solenoid Test Facility (STF) [5,6,7] which is located in the Central Helium Liquifier building (CHL) at Fermilab.…”
