Abstract-The RF coupling coil (RFCC) module of MICE is where muons that have been cooled within the MICE absorber focus (AFC) modules are re-accelerated to their original longitudinal momentum. The RFCC module consists of four 201.25 MHz RF cavities in a 1.4 meter diameter vacuum vessel. The muons are kept within the RF cavities by the magnetic field generated by a superconducting coupling solenoid that goes around the RF cavities. The coupling solenoid will be cooled using a pair of 4 K pulse tube cooler that will generate 1.5 W of cooling at 4.2 K. The magnet will be powered using a 300 A twoquadrant power supply. This report describes the ICST engineering design of the coupling solenoid for MICE.

Abstract-Progress in particle physics has largely been determined by development of more capable particle accelerators. This trend continues today with the recent advent of high-luminosity electron-positron colliders at KEK and SLAC operating as "B factories," the imminent commissioning of the Large Hadron Collider at CERN, and the worldwide development effort toward the International Linear Collider. Looking to the future, one of the most promising approaches is the development of muon-beam accelerators. Such machines have very high scientific potential, and would substantially advance the state-of-the-art in accelerator design. A 20-50 GeV muon storage ring could serve as a copious source of well-characterized electron neutrinos or antineutrinos (a Neutrino Factory), providing beams aimed at detectors located 3000-7500 km from the ring. Such long baseline experiments are expected to be able to observe and characterize the phenomenon of chargeconjugation-parity (CP) violation in the lepton sector, and thus provide an answer to one of the most fundamental questions in science, namely, why the matter-dominated universe in which we reside exists at all. By accelerating muons to even higher energies of several TeV, we can envision a Muon Collider. In contrast to composite particles like protons, muons are point particles. This means that the full collision energy is available to create new particles. A Muon Collider has roughly ten times the energy reach of a proton collider at the same collision energy, and has a much smaller footprint. Indeed, an energy frontier Muon Collider could fit on the site of an existing laboratory, such as Fermilab or BNL. The challenges of muon-beam accelerators are related to the facts that i) muons are produced as a tertiary beam, with very large 6D phase space, and ii) muons are unstable, with a lifetime at rest of only 2 µs. How these challenges are accommodated in the accelerator design will be described. Both a Neutrino Factory and a Muon Collider require large numbers of challenging superconducting magnets, including large aperture solenoids, closely spaced solenoids with opposing fields, shielded solenoids, very high field (~40-50 T) solenoids, and storage ring magnets with a room-temperature midplane section. Uses for the various magnets will be outlined, along with R&D plans to develop these and other required components of such machines.

“…As a result, the ability for the 4 K cooler to operate in a magnetic field will be one of the selection criteria for the type of cooler to be used. The MICE channel shown in FIGURE 1 has three types of magnet modules, the tracker magnet module [2], the absorber focus coil (AFC) module [3] and the RF coupling coil (RFCC) module [4]. The tracker module consists of a threecoil spectrometer magnet that produces a uniform field and two match coils.…”

Small 4 K coolers are used to cool superconducting magnets. These coolers are usually used with high temperature suerconductor (HTS) leads. In most cases, magnet is shielded with iron or active shield coils. Thus the field at the cooler is low. There are instances when the cooler must be in a magnetic field. Gifford McMahon (GM) coolers or pulse tube coolers are commercially available to cool the magnets. This paper will discuss how the two types of coolers are affected by the stray magnetic field. Strategies for using coolers on magnets that generate stray magnetic fields are discussed
