	The LIPAc accelerator aims to operate in Rokkasho Fusion Institute a 125 mA/CW deuteron beam at 9 MeV to validate the concept of IFMIF's accelerators that will operate in CW 125 mA at 40 MeV. The 2.45 GHz ECR injector developed by CEA-Saclay is designed to deliver 140 mA/100 keV CW D⁺ beam with 99% D⁺ fraction ratio. Its LEBT relies on a dual solenoid focusing system to transport and match the beam into the RFQ. The normalized RMS emittance at the RFQ injection cone is required to be within 0.25π mm·mrad to allow 96% transmission through the 9.81 m long RFQ. An equal perveance H⁺ beam of half current and half energy as nominal with D⁺ is used to avoid activation during commissioning. The injector commissioning at Rokkasho is divided into three phases to characterize the emittance between the two solenoids of the LEBT (A1) and just downstream the RFQ injection cone (A2) and the extraction system of the source (A3). Phase A1 has been achieved and phase A2 continues in 2016 in order to reach the required beam parameters and to match the beam into the RFQ. This paper reports the commissioning results of phase A1 and the intermediate ones of phase A2 for H⁺ and D⁺ beams.

WEPP01	High Intensity Beam Production at CEA/Saclay For The IPHI Project	ion, proton, diagnostics, solenoid	83

	CEA/Saclay is involved in high power proton accelerators for long years. This activity started in the 90's, with the development of the SILHI source which routinely produces tens mA of proton beam. Several industrial difficulties led to a very long IPHI RFQ construction process. The 352 MHz RFQ conditioning is presently in progress. Before the completion of the conditioning in CW mode, tests with pulsed proton beam have been decided. As a consequence, the SILHI source recently produced very short H⁺ beam pulses in order to allow the first IPHI beam acceleration. Such very short pulses, in the range of few hundred microseconds, allowed analyzing the beam loading of the RFQ cavity as well as conditioning the middle energy diagnostic. This article will focus on the source parameters and beam characteristics in the low energy beam line leading to the best RFQ transmission.

WEPP34	Recent Beam Dynamics Studies for the SCL Demo of RISP	ion, lattice, simulation, emittance	122
	H. Jin, I.S. Hong, J.-H. Jang IBS, Daejeon, Republic of Korea
	The Rare Isotope Science Project (RISP) has been developed the RAON accelerator to accelerate heavy ion and rare isotope beams for the various kinds of science programs. In the RAON accelerator, the beams created by a superconducting electron cyclotron resonance ion source (ECR-IS) will be accelerated by the Radio Frequency Quadrupole (RFQ) after passing through the Low Energy Beam Transport (LEBT) section. These accelerated beams will pass the Medium Energy Beam Transport (MEBT) section for the beam matching and be re-accelerated by the superconducting linac (SCL) for the higher beam energy. Prior to the construction of the RAON accelerator, the performance of each component of LEBT, RFQ, MEBT and SCL should be examined for the efficient mass production. Accordingly, we have been constructing the test facility, which is named SCL demo, since 2015. First beam test with an oxygen beam will be carried out at the end of 2016 and the next test with a bismuth beam will be performed in 2017. In this paper, we will present the beam dynamics studies with the recent lattice design of the SCL demo and describe the simulations results with the oxygen and bismuth beams.
