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.

In addition to wave properties like polarization, harmonic number, high- or low-field side launching, and launch angle, absorption of electron cyclotron waves depends strongly on plasma parameters, such as the temperature. Therefore, we have introduced a new way of operating our 110-GHz gyrotron for electron cyclotron heating and electron cyclotron current-drive experiments. In the Rijnhuizen Tokamak Project (RTP), a system for feedback control of the plasma temperature by regulating the output of the gyrotron has come into operation recently. Other parameters, i.e., the Shafranov parameter = pol + li/2 - 1, and the loop voltage can be under feedback control as well. The control system is described and some test results are given.
