1. AEGIS Magnet System

2. What To Built Two solenoids 5 T& 1 T with homogenous field
Persistent mode of operation
Two separated vessels
Operate for a few days without refilling
Passive quench protection system

3. Homogeneity and Field For 1 and 5 Tesla region:
in cylinder 100x600 mm 10e-3
in cylinder 10x100 mm e-5
Bore diameter: 180 mm for 4.5 K surface
Bore gap: 200 mm for 80? K surface with > 0.7T
Anti-coil to reduce field in the measurement area is required

4. Field Distribution to be similar to:

5. Field Lines

6. Components of Magnet System
Solenoids
Correction Coils
Superconducting Switches
Current Leads (HTS)
Diodes and Protection Resistors
Power Supplies (200 A, 50 A, 10 A, 1A)

7. Wire dimensions (bare)
Superconducting Wire
Number of filaments 42
Cu/Sc ratio
4.0
Wire dimensions (bare)
1.19 x 0.74 mm

8. Coil Winding
Don’t forget about winding spool

9. Tests to Be Performed Single Solenoid Test before Integration:
Such test can be performed in vertical cryostat available at CERN
Field Mapping and Field Correction Test:
Warm bore tube has to be foreseen as part of final vessel design
Quench Test to be done at the same time

10. Cryostat Vacuum Vessel N2 Vessel He Vessel
Temperature Monitoring and Level Meters
Adjustable Support Structure for He (External)
Monitoring of Vessel’s Position?
Valves and Ports
Transfer Lines
