Superconducting solenoids developed for the Fermilab Mu2e require an extended R&D on superconductor cables performance, working in strong field in the critical currents range. To test these cables, the Mu2e Cable Test Solenoid was designed and fabricated at Fermilab. The solenoid contains three coils (two Main coils, and one Test coil), connected i...

... different solutions and etching temperature regimes. The best results for the etching were obtained using the hot 50% NaOH solution. It looks practical to remove most of aluminum from the cable mechanically prior to etching to expedite the etching process. Some Riken cable samples with the etched off aluminum stabilizer on the end are shown in Fig. 7. The upper sample demonstrates the non-machined cable etched for 8 hours. The two lower samples were pre-machined on one side, and then etched for one hour. The machining of aluminum on one cable side only was done in attempt to keep the aluminum stabilizer all over the splice area, but unfortunately, aluminum was etched off all around ...
