FUZIOTECH is capable to provide turnkey solutions of one of a kind devices. In the last decade a reach selection of manufacturing partners have been collected.
The three stages of the shutter covering the pinholes are shown both in CAD and in reality.
To avoid further contamination of the in-vessel AXUV camera sensors exposed to the plasma and therefore to improve the efficiency of the TCV tokamak bolometer diagnostics, shutter systems have been installed to them.
The modification involved challenges such as drilling and installing a pipe housing the actuator of the rotary shutter through the cooling chamber, electron beam welding of small wall thicknesses, machining high precision pinholes applying spark erosion technique, manufacturing of special materials (e.g. NINOMIC, INCONEL, etc.) and applying special highly non-reflecting coatings.
