The RFQ of the project IPHI is a 8 meter long, 352 MHz frequency, high power, very precise tolerancies (0,01 mm on 1 meter long for example)device to accelerate protons. This RFQ is similar to the RFQ of the LEDA project. So, we realise thermal and mechanical studies followed by different tests for machining and brazing copper and for brazing copper with stainless steel. We describe in this paper those differents steps and the way we proceed to supply the fabrication itself by an independant company.
