Abstract-Fermilab is working on the development of high field magnet systems for ionization cooling of muon beams. The use of high temperature superconducting (HTS) materials is being considered for these magnets using Helium refrigeration. Critical current (I c ) measurements of HTS conductors were performed at FNAL and at NIMS up to 28 T under magnetic fields at zero to 90 degree with respect to the sample face. A description of the test setups and results on a BSCCO-2223 tape and second generation (2G) coated conductors are presented.

“…The cracks generated during the pyrolysis stage made it hard to produce high-I c YBCO films since they were maintained after the firing stage. Thus, a multi-coating method has been developed to increase the film thickness of YBCO by several groups [10,11], which is, however, inappropriate for a high throughput process of long-length CCs. An alternative approach is to increase the thickness of the single-coat YBCO film.…”

“…The coating processes allow a 40 mm or wider process width. After YBCO reaction and Ag coating the conductor is slit to near-final conductor width, typically 4 mm [5,6]. This slit "insert" conductor is then laminated on both sides to a slightly wider (4.4 mm) foil, which can consist of different materials.…”

“…Figure 2 shows the geometrical configuration of a tape and relative directions of magnetic field. Flux pinning in YBCO can be strongly influenced by additions of rare earth oxides, in particular when they segregate as small particles ("nanodots") which tend to enhance pinning for field orientations perpendicular to the YBCO film plane [6,7]. Stacking faults are very effective in enhancing pinning for field orientations parallel to the film plane.…”

“…To use the advantages of both pinning mechanisms a Double Layer Hybrid was developed. An example is shown in Figure 3 at right [6], where nanodots (see bottom TEM image) enhance the perpendicular-field I c values and the planar 124 stacking faults (top TEM image) maintain effective ab-plane pinning. Figure 3 (left) also shows that at 77 K, 1 T the performance of this new conductor using this hybrid YBCO layer, approximately 1.4 µm thick, is enhanced over the entire angular range.…”

An experiment is in the works at Fermilab to confirm that ionization cooling is an efficient way to shrink the size of a muon beam. This would pave the way for Muon Collider machines, which however require in their last stages of acceleration very high field solenoids. The use of high temperature superconducting materials (HTS) is being considered for these magnets using Helium or higher temperature refrigeration. A sample holder was designed to perform critical current (I c ) measurements of HTS conductors under externally applied magnetic fields varying from zero to 90 degree with respect to the c-axis. This was performed in an ample range of temperatures and magnetic field values. A description of the test setup and results for (Bi,Pb) 2 Sr 2 Ca 2 Cu 3 O x (BSCCO-2223) tapes, and Second Generation HTS in the form of 348 superconductor are presented.
