302.02.07 Structures Status Magnet Series MQXFA09 Status Notes Two coils no longer available (in A14b, A15); Structures used in MQXFA11; will be renamed MQXFA24 Disassembled Dye penetrant testing to be performed before finishing work Work to be completed before MQXFA17 starts. Dye penetrant should be applied this week, probably before Wednesday MQXFA12b First thermal cycle complete; SG data shown after this update MQXFA13b Could Coil 242 be candidate for replacement? (reviewed with magnet originally) MQXFA17 Arrived from BNL; will be worked on after MQXFA18 moves to shipping crate Placing in the crate will be done this week. Hands off and specs. meeting scheduled for Thursday and Friday this week Could ship as early as 8/24. MQXFA18 should be shipped before MQXFA16 arrives. We don t have space for so many magnets (we currently have MQXFA12b, 18 and 17 onsite) MQXFA18 Will be on hold until A17 rework is completed MQXFA19 302.02.07 Structures Status, 12-Aug-24 2
302.02.07 Structures Status 2 Series Magnets (cont.) Updated Magnet specifications to allow for 120 MPa excursions, increased from 110 MPa MQXFA07b, MQXFA16, MQXFA15 reload did not require 120 MPa MQXFA17 reached 120 MPa during preload MQXFA13b coil 2 reached 126 Mpa in last excursion 302.02.07 Structures Status, 12-Aug-24 3
