“…The type of cooler used to cool the AFC magnet and the liquid absorber is also determined by the presence of a magnetic field. Because the level of the magnetic field is an issue in MICE, the PT415 coolers will be used on the other MICE magnets [9]- [10].…”

Abstract-The MICE focusing solenoids have three 4 K coolers (two for the superconducting magnet and one for the liquid absorber) and four HTS leads that feed the current to the focusing coils. The focusing solenoids produce large radial external fields when they operate with the polarity of the two coils in opposition (the gradient or flip mode). When the MICE focusing coils operate at the same polarity (the solenoid or nonflip mode), the fields are much smaller and parallel to the axis of the solenoid. The worst-case magnetic field affects the selection of the cooler and the HTS leads. This magnetic field can also determine the height of the service towers that house the three coolers and the four HTS leads. This paper shows the criteria used for Cooler selection, HTS lead selection, and the position of both the cooler and leads with respect to the solenoid axis of rotation.

The Muon Ionization Cooling Experiment (MICE) [1] will demonstrate ionization cooling in a short section of a realistic cooling channel using a muon beam at Rutherford Appleton Laboratory (RAL) in the UK. The MICE RF and Coupling Coil (RFCC) Module consists of a superconducting solenoid mounted around four normal conducting 201.25-MHz RF cavities. The coil package that surrounds the RF cavities is to be mounted in a 1.4 m diameter vacuum vessel. The coupling coil confines the beam in the RFCC module within the radius of the RF cavity beam windows. Each coupling magnet will be powered by a 300 A, 10 V power supply. The maximum design longitudinal force that will be carried by the cold mass support system is 0.5 MN. The detailed design and analysis of the coupling magnet has been completed by ICST. The primary magnetic and mechanical design features of the coils are presented in this paper.

“…The cooling channel for MICE consists of three types of solenoid magnets; 1) the three focusing magnets that are around the liquid hydrogen absorbers [3], 2) the two coupling magnets that surround the RF cavities that re-accelerate the muons to restore their longitudinal momentum [4], and 3) the two spectrometer magnets that are used to analyze the muon beams entering and leaving the cooling channel [5].…”

“…When INFN Genoa dropped out of the MICE collaboration, the task of fabricating of the spectrometer magnets fell to the Lawrence Berkeley National Laboratory (LBNL). The LBNL design is based on the use of a Nb-Ti superconductor with a copper to superconductor ratio of four [5]. The LBNL magnet is designed to be cooled using three 1.5 W pulse tube coolers.…”

Abstract-The purpose of the MICE spectrometer solenoid is to provide a uniform field for a scintillating fiber tracker. The uniform field is produced by a long center coil and two short end coils. Together, they produce 4T field with a uniformity of better than 1% over a detector region of 1000 mm long and 300 mm in diameter. Throughout most of the detector region, the field uniformity is better than 0.3%. In addition to the uniform field coils, we have two match coils. These two coils can be independently adjusted to match uniform field region to the focusing coil field. The coil package length is 2544 mm. We present the spectrometer solenoid cold mass design, the powering and quench protection circuits, and the cryogenic cooling system based on using three cryocoolers with re-condensers.
