Items for followup from previous meeting

  1. Power supply. Current ~ 15KA, voltage 5-10 V. (Could existing power supply 3KA/10V be converted to 6KA/5V?)
    • Elton will obtain cost estimates for this power supply
  2. 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. Provide details to Ettore
  3. High-current HTS (17KA) vapor cooled leads
    • Ettore will provide this information based on Sultan design
  4. 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.

Tentative Agenda

  1. Update on action items
  2. Input from MIT (Minervini)
  3. Path forward (Ettore)
