Abstract

As the main magnetic confinement thermonuclear fusion experiments become increasingly large, and the pulse lengths extend beyond a few seconds, there may be some advantage in being able to control the position of ancillary equipment. This equipment operates in a radioactive environment, subject to intense magnetic fields, and may only be accessible using remote manipulators. A water-based hydraulic system has been used to control the position of a large microwave array in the JET tokamak, with a positional resolution of about 1 mm and a frequency response of 4 Hz. After an extended commissioning phase, the system has worked effectively in moving the launcher to follow preset waveforms during JET pulses.
