1. HTS High-Field Solenoid Development March xx, 2013 Presenter’s Name | DOE Mini-Review of MAP (FNAL, March 4-6, 2013)1 Advanced Quench Protection System Plan built on significant results from PBL/BNL solenoid last year:  B o >15 T (record), B peak >16 T in full insert (25 mm, 14 pancakes )  B o > 6 T, B peak > 9 T in half midsert (100 mm, 12 pancakes) Made significant enhancement (more channels) in advanced quench protection system. This activity is partly supported by MAP Fabricated full midsert (24 pancakes). Tested it with insert at 77 K Full midsert worked well (see below) and is ready for test at 4K Several pancakes (at least four) of insert got damaged during the 77 K testing. Apparent cause: excessive thermal strain – the robust mechanical structure prevented good cooling.

2. BSCO 2212 Conductor Development Limitations in wire J c overcome – major breakthrough –Impurities reduced / internal gas pressure controlled through overpressure processing (an OST-FSU-Fermilab collaboration) –Leakage prevented –J c approaches short sample values (≈2X increase) Cable development studies underway: Next step: wind, react, and test cabled-based coils w/ overpressure processing March xx, 2013 Presenter’s Name | DOE Mini-Review of MAP (FNAL, March 4-6, 2013)2 Comparison of 1 m long cable and single-strand barrel sample Both cable and wire are clean and free of leakage after reactions Cable Single Strand Cable is ‘6-around-1’: 6 - 2212 strands round a central Fe-Cr-Al high-temperature alloy wire No loss of I c in cable
