	A.V. Ziiatdinova MEPhI, Moscow, Russia L. Bellan, M. Comunian, A. Pisent INFN/LNL, Legnaro (PD), Italy A.V. Ziiatdinova ITEP, Moscow, Russia
	SPES (Selective Production of Exotic Species) is a facility intended for production of neutron-rich Radioactive Ion Beams (RIBs) at the National Institute of Nuclear Physics (INFN-LNL, Legnaro, Italy). Exotic nuclei production based on the ISOL (Isotope Separation On-Line) technology using UCx target. Neutron-rich nuclei will be generated by uranium fission under the influence of proton beam from cyclotron. After that, RIBs will be reaccelerated by the ALPI (Acceleratore Lineare Per Ioni). RFQ (Radio Frequency Quadrupole) will be used as a front-end part of the ALPI. Double drift double buncher system is planned to install before RFQ for increasing transmission. This article is dedicated to beam dynamic simulation and laying-out of transport line at section before ALPI.

	M. Comunian, L. Bellan, F. Grespan, A. Pisent INFN/LNL, Legnaro (PD), Italy M. Eshraqi, R. Miyamoto ESS, Lund, Sweden
	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% (a beam pulse of 2.86 ms, 14 Hz repetition period) and will accelerate a proton beam of 62.5 mA pulse peak current from 3.62 to 90 MeV. This article describes the commissioning strategy plans for the DTL part of the linac, techniques for finding the RF set-point of the 5 tanks and steering approach. Typical beam parameters, as proposed for commissioning purposes, are discussed as well and how the commissioning sequence of the tanks fits together with ongoing installation works in the tunnel.

Civil construction of the accelerator tunnel has made good progress and will allow starting installation of the normal conducting frond end (NCFE) by end of 2017. To achieve these milestones the design of all major beam line components have been completed and the construction of the subsystems begun. We report on the advancement of the subsystems and the commissioning progress of the microwave discharge Proton Source (PS-ESS).

	A. Pisent INFN/LNL, Legnaro (PD), Italy
	All 18 sections of the IFMIF RFQ were completed in summer 2015. A 2 m section (the last three modules and one prototype used as RF termination) were RF tested at LNL at the design value of 90 kW/m in cw conditions. The three 3.3 m long supermodules were sent to Japan in January 2016. The RFQ was installed and tuned with fixed tuners to the nominal field frequency and field distribution. The very high design shunt impedance was achieved.

THPLR049	Tuning the IFMIF 5MeV RFQ Accelerator	969
	A. Palmieri, F. Grespan, A. Pisent INFN/LNL, Legnaro (PD), Italy
	In order to allow proper operation of the IFMIF RFQ, it is necessary to perform a campaign of RF measurements on the cavity aimed, on one hand, at determining the basic RF parameters (frequency, Q0, etc.), on the other hand at verifying the fulfilment of the voltage law within the specified admitted range (±2% target value, ±4% acceptance value) of any of the perturbative components upon successive tuner settings as predicted by the tuner algorithm. These measurements also involve the determination of the proper depth of the end plates and the positioning and length of the Dipole Stabilizers (if any). In this contribution the tuning procedure and the results of such measurements will be presented for the case of the IFMIF RFQ will be described.

	L. Ferrari, A. Palmieri, A. Pisent INFN/LNL, Legnaro (PD), Italy R. Dima, A. Pepato, A. Prevedello, E. Udup INFN- Sez. di Padova, Padova, Italy
	The RFQ of the IFMIF/EVEDA project is a 9.9 m long cavity able to accelerate a 130 mA deuteron beam from the input energy of 100 keV to the output energy of 5 MeV. Such RFQ operates at the frequency of 175 MHz and is composed of 18 mechanical modules approximately 0.55 m long each. The RFQ realization involves the I.N.F.N. Sections of Padova, Torino and Bologna, as well as the Legnaro National Laboratories (L.N.L.). The metrological measurements via CMM (Coordinate Measuring Machine) provided to be a very effective tool both for quality controls along the RFQ production phases and in the reconstruction of the cavity geometric profile for each RFQ module. The scans in the most sensitive regions with respect to RF frequency, such as modulation, tips, base-vane width and vessel height provided the values of the cavity deviations from nominal geometry to be compared with design physic-driven tolerances and with RF measurements. Moreover, the comparison between mechanical and RF measurements suggests a methodology for the geometric reconstruction of the cavity axis and determines the final machining of the end surfaces of each module in view of the coupling with the adjacent ones. In this paper a description of the meteorological procedures and tests and of the RFQ along its production and assembly phases will be described.

At Rokkasho site a series of test were performed in order to verify the effect of the shipment on the cavity. The assembly debug, shipment equipment and the sequence of operations are described in this paper.
