Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

START, a low-aspect-ratio tokamak located at Culham Laboratory in England, has a central copper rod that carries the whole of the toroidal field current. A small ohmic heating (OH) solenoid is wound around this central rod. The OH-driven currents in the solenoid are opposed by eddy currents in the copper rod, decreasing the volt-seconds available to drive plasma current. These eddy currents were measured and were modeled by a Laplace-transformed cylindrical heat equation. Slots in the central rod inhibit the eddy currents, increasing the effective poloidal resistance of the rod.
