Originally designed for five years of plasma operations, the JET Far Infrared (FIR) interferometer/polarimeter diagnostic system is still operating at its full capabilities nearly forty years later and in ITER relevant conditions, albeit with significantly lower neutron fluences and for several D-T campaigns. The original design changed substant…
We report on the selection, implementation and successful demonstration of a new automated laser control system for JET’s Far Infrared Interferometer, a diagnostic essential for machine protection. The new control system allows all laser subsystems and sensors to be interlocked and operated remotely in a precise and preprogramed manner, functiona…
