Production and Quality Control of the First Modules of the IFMIF-EVEDA RFQ

The IFMIF/EVEDA RFQ, designed to accelerate a 125mA D+ beam from 0.1 MeV to 5 MeV at a frequency of 175 MHz, consists of 18 modules with length of ~550 mm each. The production of the modules has been started and 2 prototype modules plus module 16 have undergone all the production steps, including precision milling and brazing. The progress of the construction and especially the fine tuning of the design and engineering phase are reported.
