Post mortem inspection AUP 105 and next steps (CERN 108)
AUP Coil 105 (already analyzed): winding and curing was in FNAL, but reaction and impregnation in BNL. MQXFA prototype coil, 4.2 m long, fabricated by LARP. Winding and curing were done at FNAL, reaction and impregnation at BNL. Fabrication started in April 2017 and ended in November 2017. It has quench heaters on Inner and Outer Layer. It was used in MQXFAP2 (2nd prototype) that was tested at BNL in October 2018. MQXFAP2 reached 15 kA at 1.9 K. It was limited by a broken Al-shell at magnet return end. Coil 105 had one training quench during MQXFAP2 test, and another quench was either in 105 or in 104 (fast logger issue).
AUP Coil 106: from the prototype that was limited due to the broken shell in the RE end, but impregnated in FNAL. Coil 106 is an MQXFA prototype coil, 4.2 m long, fabricated by LARP. It was fully fabricated at FNAL. Fabrication started in May 2017 and ended in December 2017. It has quench heaters on Inner and Outer Layer. It was used in MQXFAP2 (2nd prototype) that was tested at BNL in October 2018. MQXFAP2 reached 15 kA at 1.9 K. It was limited by a broken Al-shell at magnet return end. During MQXFAP2 test, coil 106 had 2 quenches in the Inner Layer pole turn, and nine quenches in the Outer Layer pole block.
