Education
and Maglev Research at M.I.T.
Dr. Thompson received the Ph.D., M.S. and B.S. degrees in
Electrical Engineering at the Massachusetts Institute of Technology. His
doctoral thesis at MIT "High Temperature Superconducting Magnetic
Suspension for Maglev" concerned the design and test of high-temperature
superconducting suspensions for Maglev and the implementation of
magnetically-based ride quality control. Dr. Thompson has authored a number of
papers concerning superconducting magnetic suspension design, scaling laws, and
actuation.
·
Some results of his Ph.D. thesis work and
pictures of the 1/5 scale-model magnetic Maglev suspension are here.
·
More detail of the construction and modeling of
the magnetic suspension is given in the paper here.
·
A full listing of his Maglev-related
publications is given here.
