TransportationMedicalElectronicsPower GenerationCommunications
Transportation Maglevs
Maglev has promisez Speeds in excess of 300mph possiblez Magnetic cushion reduces mechanical
wear from frictionz Less noise pollutionz Smoothest ride of any vehiclez 30% more efficient than conventional trainsz Safety collision is impossible!
Maglev How it works
Superconducting magnets on board Current induced in coils on trackAttraction/repulsion between coils and magnetUsed for magnetic levitation and lateral guidanceCarefully-timed interactions propel the train forward
Electronics - SQUIDsSuperconducting quantum interference devicesDetect magnetic flux (down to 2 pT)Uses:z Non-destructive corrosion testingz Magnetoencephalography (MEG)z Oscilloscopesz Oscillators, DA converters, Amplifiers
Electronics Particle Accelerators
Use magnets for three applicationsz Beam transport to bend and focus beamz Accelerate the particlesz Identify and analyze particle interactions
Advantages of using superconductorsz Higher fields with smaller sizez Extreme magnetic accuracy
Power Generation
Electric Generatorsz Above 99% efficient z Half size of conventional generators
Distributed Superconducting Magnetic Energy Storage System (D-SMES) z Reserve of over 3 million watts z To stabilize line voltages during grid
disturbances
Communications
Petaflop Computersz 1000 times faster than modern computersz 1000-trillion operations per second
Superconducting Cablesz 340 million Watts of power transmittedz Limited to DC current flowz Cost effective only for large power supplies
Experimentation
Determination of Resistance as a function of Temperaturez No conclusive data acquired due to varying
experimental parametersz Dr. Kingsbury (chem) confirmed difficulty of
data acquisitionDetermination of critical currentz No data due to equipment limitations
