Demonstration of superconductivity (Maglev)

Magnetic levitating vehicle

consisting of

• Vacuum cryostat
• Thermal superinsulation
• Integrated cryopump
• LN2 tank
• YBCO single grain superconductors
• Vacuum pumping valve
• Non-magnetic G10 casing
• Graphite fibre plate

Operation

• Field – cooled operation
• Levitation and guidance force by pinning
• About 100 ml LN2 for cool –down
• 18 ml LN2 storage
• 60 – 90 minutes operation (refilling possible)
• reconditioning of insulation vacuum
