Revision as of 08:48, 11 February 2011
Items for followup from previous meeting
- 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
- 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
- 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.
Tentative Agenda
- Power supply
- maximum current capability
- How much the PS can be modified to increase the current capability
- bus bar capability. Can cables be used, or are air/water cooled bus bars required?
- Cryogenic plant
- Is a secondary loop practical/feasible with an intermediate heat exchanger and recirculating pump in order to comply with the pressure (~6 bar) and pressure drop (~0.5 bar) needed for the CIC conductor.
