I. Our Project
3
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.

Schematics and models
5
Rail Systems

• We tested possible rail systems for durability
  and levitation.

6
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.

The Physics
9
Magnetic Flux Lines

• All magnetic objects produce invisible lines of
  force that extend between the poles.

10
Meissner Effect/Perfect Diamagnetism

• Magnetic field lines penetrate most objects.
• However, below their Tc and Hc , superconducting
  materials exclude field lines (flux).

11
Magnetic levitation

• Demonstration of the Meissner effect.

12
Crystal Lattice

• There are often imperfections in the
  superconductors lattice structure.
• YBCO crystal lattice structure

13
Flux Pinning

• Flux tubes penetrate the lattice and become
  affixed to the imperfections.

Magnetic Suspension

• Click on the picture to start the movie.
• Once pinned, an elevated magnet can suspend a
  superconductor beneath it.

III. The History of Magnetic Levitation Vehicles
16

• 1750 John Mitchell conducted the first
  experiments measuring the magnetic forces between
  the poles of a magnet . The principle of
  magnetic force is critical to Maglev train
  operation.

17

• 1900 Robert Goddard and Emile Bachelet conceive
  the concept of frictionless trains.

18

• 1969 American scientist James R. Powell and
  Gordan T. Danby patented the first design for
  Maglev trains.

19

• 1970 German and Japanese engineers start
  research and development towards their versions
  of Maglev technology.

20

• 1990 The initial phase of the Yamanashi Maglev
  Test Line commences.

21

• 2003 The Shanghai Transrapid Maglev Line is
  inaugurated.

22
III . The Future
23
Maglev Trains

• Room temperature superconducting magnets
• Generating energy at faster speeds using less
  energy at lower cost

24
NASA

• Maglev technology could give space vehicles a
  running start to break from Earths gravity.

25
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.
