  The Drift Tube Linac (DTL) of the European Spallation Source (ESS) is designed to operate at 352.2 MHz with a duty cycle of 4% (3 ms pulse length, 14 Hz repetition period) and will accelerate a proton beam of 62.5 mA pulse peak current from 3.62 to 90 MeV. In this paper the DTL mechanical design and simulations are presented, together with the results obtained from the prototypes of three drift tubes, equipped respectively with Permanent Magnet Quadrupole, Steerer and Beam Position Monitor.

  The Linear IFMIF Prototype Accelerator, the high intensity deuteron linac compact demonstrator of the IFMIF machine, is in an advanced installation phase at BA site (Rokkasho, Japan), within a European-Japan collaboration coordinated respectively by F4E and JAEA. The RFQ (5 Mev, 130 mA) is an Italian in-kind contribution under the responsibility of INFN. Is it a 9,8 m-long structure made of 18 modules, pre-assembled in three parts. The various aspects of the RFQ integration inside the LIPAc are presented here, with details about the various functional services of the RFQ, the different interfaces with other sub-components of the linac and with the building and the structural validation through the seismic analysis. Some peculiar aspects related to the installation of the RFQ are also detailed (i.e. the handling tooling, precise positioning jigs).
