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.

We have studied the feasibility of an efficient current-drive scheme using radio-frequency (rf) waves on the alpha particles produced in a reactor tokamak. Traveling fast waves, generated as waveguide modes in the plasma, are found to be particularly suitable for implementing such a scheme. The scheme involves using rf power to prohibit the alpha particles from slowing down isotropically and in pushing the alpha particles in a preferential direction and thus form an alpha-particle beam, which, through interaction with electrons, sustains a current. Numerical estimates for the current-drive efficiency were obtained using plasma parameters characteristic of the Argonne National Laboratory design of a reactor tokamak.
