Supply of eight radio-frequency feed-through flanges for the collection of radio-frequency signals from the eight position monitors inside the IFMIF / EVEDA Cryomodule. These flanges, which act as a transition between the exterior of the module and the interior of the SRF Linac,. The flange design is optimized for phase stability,low thermal losses, radiation resistance and connection reliability and the flanges will operate as an insulator between the insulation vacuum of the (10-3 Pa) cryostat and the atmosphere. The degassing ratio of the flanges with their connectors must be less than 1*10-7 Pa·m3·s-1 per cable after 100 h under vacuum. The vacuum leak rate must be less than 2*10-11 Pa·m3·s.
