REBCO WG meeting

Monday 13 Dec 2021, 11:00 → 12:40 US/Pacific

• What performances and parameters should the conductor have? How can we make magnets using these conductors? 
• What is the maximum dipole field a REBCO magnet can generate?  
• What is the magnet performance? How does it quench? What is the field quality? 
• Does the magnet performance degrade, e.g., during operation, after thermal cycles? If so, how can we prevent it?  
• How can we characterize the performance for long conductors? 

1 A new winding and fabrication concept for racetrack coils using CORC cables

Zachary Johnson from ACT will present a new concept on the winding and fabrication of racetrack coils using CORC cables. This concept can be directly applied to the MDP common coil magnet and the following ACT/BNL STTR project.

Speaker: Zachary Johnson (Advanced Conductor Technologies, LLC)

2 Q & A

Speakers: Anis Ben Yahia (Brookhaven National Laboratory), Danko van der Laan (Advanced Conductor Technologies, LLC), Jeremy Weiss (Advanced Conductor Technologies, LLC), Paolo Ferracin, Ramesh Gupta (BNL), Reed Teyber (LBNL), Stephen Gourlay (LBNL), Vadim Kashikhin (Fermilab), Vito Lombardo (Fermilab), Xiaorong Wang (LBNL), Zachary Johnson (Advanced Conductor Technologies, LLC)

• ACT will make the MDP common coil magnet based on the concept presented by Zachary Johnson, in collaboration with BNL. ACT plans to order the hardware by the end of January 2022. Need to incorporate the design features necessary for the instrumentations by then.  
• With the support from ACT and BNL, Maxim and Reed will look into the instrumentation needs, e.g., co-wound sensors, spot heaters, and sensors at the termination. Will keep Ramesh and Piyush in the loop on the instrumentation plan. 
• Conductor diameter around 6.5 mm. Prefer not to have any instrumentation between the conductor and groove.
