Items for followup from previous meeting
- None
Tentative Agenda
- Background (Elton)
- Discussion of items Ettore sent via e-mail
Minutes
Attending: Ettore, Elton, George, Tim, Jonathan, Elliott
- Discussion of implication of cable-in-conduit conductor (CICC) choice on infrastructure in four main areas
- Power supply. Current ~ 15KA, voltage 5-10 V. (Could existing power supply 3KA/10V be converted to 6KA/5V?)
- Elton can obtain cost estimates for this power supply
- Cryogenic plant
- Primary circuit: Forced flow He at 4.5K, < 10g/s, ~5-10 bar, pressure drop < 2 bar.
- Secondary circuit: Deliver intermediate temperature He gas at 20-70 K to HTS vapor cooled current leads
- Jonathan will investigate feasibility/cost of modifying existing refrigerator or purchasing new to deliver these requirements
- High-current HTS (17KA) vapor cooled leads
- Ettore will provide this information based on Sultan design
- Fast protection system (external), with response time of ~0.5 s.
- Commercial 4 parallel breakers 5KA each (20KA total), 2KV max. Two independent systems for redundancy
- Ettore will obtain details of these existing systems.
- Power supply. Current ~ 15KA, voltage 5-10 V. (Could existing power supply 3KA/10V be converted to 6KA/5V?)
- Jonathan will provide details of the cryo plant to Ettore
- George mentioned that the G0 CICC conductor may have been operated at reduced pressure and lower current, which may be more compatible with standard JLab operation.
