	CEA is in charge of the design, construction, installation and commissioning at SNRC of the Linac of the SARAF project. The linac is composed of an MEBT and a Superconducting linac (SCL) integrating 4 cryomodules. Nowadays, the HWR cavities and superconducting magnets prototypes are being built. The Critical Design Review of the cryomodules has just been passed in March 2018. This paper present the status of the SARAF-LINAC cryomodules.

	The progress in R&D of QWR and HWR superconducting cavities will be discussed. These cavities are designed for the new injection linac constructed for Nuclotron-NICA complex at JINR. The goal of new linac is to accelerate protons up to 25 MeV (and up to 50 MeV at the second stage) and light ions to ~7.5 MeV/u for Nuclotron-NICA injection. Current results of beam dynamics simulations, SC cavities design and SRF technology development will be presented in this report.

	Funding: Work supported by National Basic Research Project (No. 2014CB845504) Beijing isotope separation on line type rare ion beam facility (BISOL) for both basic science and applications is a project proposed by China Institute of Atomic Energy and Peking University. Deuteron driver accelerator of BISOL would adopt superconducting half wave resonators (HWRs) with low beta and high current. The HWR cavity performance and the beam dynamic simulation of the superconducting deuteron driver accelerator will be presented in this paper.

TUA2WC04	High RF Power Conditioning of the RISP RFQ
	B.-S. Park, C.O. Choi, I.S. Hong, H. Jang, D.Y. Lee, K.T. Seol, K.T. Son IBS, Daejeon, Republic of Korea
	Funding: This work was supported by the Rare Isotope Science Project of Institute for Basic Science funded by the Ministry of Science, ICT(MSIT) and the National Research Foundation of Korea(2013M7A1A1075764). A CW radio frequency quadrupole (RFQ) accelerator has been designed, fabricated and installed to accelerate from proton to uranium for the Rare Isotope Science Project (RISP). The RISP RFQ is a four-vane type with a ramped inter-vane voltage profile to reduce the length and has 81.25 MHz operational frequency. The RFQ cavity consisted with nine modules, made by brazing eight segments composed with the oxygen free electric (OFE) copper, has a length of five meters and a diameter of one meter. High RF power system was composed with two 80 kW solid state power amplifier (SSPA). The high RF power can be feeding through two power coupler which can support more than 100 kW. The power from each SSPA is supplied to the cavity and the phase difference is compensated by controlling the cable length on the low power level. The designed power dissipation is 94 kW on the RFQ cavity. In this paper, the high RF power conditioning results will be reported from pulse mode to CW mode.
