The vacuum tests of the first segment of the ESS Bilbao RFQ have been successfully completed. The RFQ is a linear accelerator that serves as a bridge between high-voltage of the ion source and the Accelerator cavities named DTL. It is a key component since it accelerates protons from 45keV to 3MeV keeping the beam focused. The peculiarity of the ESS Bilbao RFQ, consisting of 4 segments with a total length of about 3 meters, is that the vanes that form each of the segments are assembled with polymeric vacuum gaskets and are not conventionally welded by brazing. This innovative assembly system technology has been previously used in the RFQ manufacturing process of the RAL-ISIS neutron source and reference center in the field.
