REBCO WG meeting #5

Thursday 21 May 2020, 11:00 → 12:00 US/Pacific

Anis Ben Yahia (Brookhaven National Laboratory), Ernesto Bosque (NHMFL), Ramesh Gupta (BNL), Stephen Gourlay (LBNL), Vadim Kashikhin (Fermilab), Vito Lombardo (Fermilab), Xiaorong Wang (LBNL)

• 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? How to protect the magnet during a quench? What is the field quality? 
• How can we characterize the performance for long conductors? 

11:00 → 11:10 Followup and update

Further thoughts and plans on the tape/conductor characterization

Speakers: Anis Ben Yahia (Brookhaven National Laboratory), Ernesto Bosque (NHMFL), Ramesh Gupta (BNL), Vadim Kashikhin (Fermilab), Vito Lombardo (Fermilab), Xiaorong Wang (LBNL)

• Vito and Ernesto will plan for a calibration test at FNAL using the tested samples at ASC.  
• The current goal is to recover the test capability on REBCO tapes at FNAL to meet future MDP needs. 
• Two more things to consider for future measurement needs:
  • Measure the I_c of round wires at certain bending radii in background fields.
  • Measure the I_c of REBCO tapes at elevated temperatures.  

11:10 → 11:30 Input for hybrid design study

List of parameters and plans to get the data (literature survey, new experiments etc)

Speakers: Anis Ben Yahia (Brookhaven National Laboratory), Ernesto Bosque (NHMFL), Ramesh Gupta (BNL), Vadim Kashikhin (Fermilab), Vito Lombardo (Fermilab), Xiaorong Wang (LBNL)

• Include the published parameterization of REBCO tapes. How well does it describe the wire transport performance?   
• Provide input on the draft and send the first version to Paolo by 5/28.

11:30 → 11:50 CORC CCT development

Speaker: Xiaorong Wang (LBNL)

• Discuss the 4.2 K test results during meeting #6.
• Useful to check the impregnation of short wires.
  • Wires could contain less tapes. 
  • Check the impact of different overlap between heat shrink tubing.
