Magnetic suspension and levitation train
The HTS Team
Tuesday morning research update meeting.
Lead by our mentor, Dr. Hascicek.
Attended by Yalcin Akin, our graduate student mentor, and the other in-lab researchers.
Testing the Superconductors
Batch 1: Appeared not to be superconducting.
Batch 2: Marginally superconductive – even after oxygenation.
Batch 3: Melted by its own protective epoxy coating.
Magnetic Flux Lines
All magnetic objects produce invisible lines of force that extend between the poles.
Meissner Effect/Perfect Diamagnetism
Magnetic field lines penetrate most objects.
However, below their Tc and Hc , superconducting materials exclude field lines (flux).
Flux Pinning
Flux tubes penetrate the lattice and become affixed to the imperfections.
Maglev Trains
Room temperature superconducting magnets
Generating energy at faster speeds using less energy at lower cost
Maglev Space Propulsion
Launching systems would use magnetic fields to levitate and accelerate a vehicle along a track .
Reaching the end of the track, the vehicle could switch to more conventional rocket engines.
