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…
In future demonstration fusion power plants, plasma facing components will face high steady state and ultra-high transient heat loads from the plasma. Introducing low thermal conductivity features to the component can reduce the peak temperatures seen by the coolant pipe, but at the trade-off of a loss of steady-state performance. Producing low-con…
