A Q machine with a rotating cathode structure and a limiter-type heat shield is described, which achieves an azimuthally symmetric and radially uniform profile of plasma density and potential. The point of emphasis is that a long time operation is realized by utilizing the latest technique of vacuum-and water-tight feedthroughs, yielding a plasma source for basic experiments with higher accuracy.
