REBCO WG meeting

Thursday 4 Nov 2021, 11:00 → 12:20 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 Status update

• Subscale common coil
• COMB
• CCT

Speakers: Anis Ben Yahia (Brookhaven National Laboratory), Maxim Martchevskii, Ramesh Gupta (BNL), Reed Teyber (LBNL), Vadim Kashikhin (Fermilab), Vito Lombardo (Fermilab), Xiaorong Wang (LBNL)

• Common coil: news to come for the next meeting.
• COMB: sent the bent sample on the fixture to ACT for further test. The goal is to understand what caused the surprising degradation after re-lubrication.
• C3: subscale mandrels being machined. Will start winding once the conductor arrives. 

 

• Thoughts that will be pursued:
  • Vadim suggested to look into alternative dipole magnet design using tape stacks. 
  • Along the same line, conductors alternative to CORC should be evaluated.
