Supply of Multi-pin electrical feedthroughs and connectors for LEVI system

The LEVI system must accommodate several signal types as required by different diagnostic systems, therefore the awarded contractor shall provide the connector’s design (i.e hermetic electrical feedthrough connectors + connection plug) compatible with the ones listed in Table 2 A preliminary list of requirements for these electrical feedthroughs is listed below: • All feedthroughs must have a weldable interface to allow integration within the LEF • Feedthroughs must be push pull type to allow RH compatibility. Each connector shall be able to sustain an axial misalignment of +/-0.8mm and +/-5°. • The port plug is baked 500 times on the ITER Life-time. The connectors and accessories shall be able to withstand 500 baking cycles from 20°C to 240°C while keeping the electrical and mechanical properties • Operating temperatures for the feedthroughs is between 20 and 120ºC • All the boundaries between UHV/Interspace/AIR shall be leak tested and remain He leak tight to 2.69 x 10-10 Pa.m3 .s-1 (helium-equivalent; normal pressure), whatever the conditions. • All the materials shall be halogen free. • The connectors shall withstand a cumulated dose greater than 10 MGy and 1 ∙ 1017 n/cm2 neutron fluence while keeping electrical and mechanical properties. The compliance can be justified by the material selection with support from IO experts
