	Funding: This work was supported by the Ministry of Science, ICT and Future Planning of the Korean Government Korea multi-purpose Accelerator Complex (KOMAC) has been operating 20 MeV and 100 MeV proton beamlines to provide proton beams to users since 2013. The new beamline and target irradiation facility, which is proposed applicable to development of the detector and simulation of the space radiation, have being constructed for low-flux proton utilization at this year. The new beam lines have the 100 MeV of maximum beam energy and 10 nA of maximum beam current. The new beam line was designed to operate with maximum duty 8%, the flux density of proton beam can be reduced to the 1/10,000 by the graphite collimator. The extracted proton beam energy can be adjustable by the double wedge type energy degrader and also, the beam energy can be selected by dipole magnet. In addition to the two sets of the octupole magnets were prepared for uniform beam irradiation with the ± 5% uniformity. In this paper, the initial operation results of the constructed new beam line is be described.

TUPVA108	Development of 1 MeV/n RFQ for Ion Beam Irradiation	2343
	H.S. Kim KAERI, Daejon, Republic of Korea Y.-S. Cho, H.-J. Kwon, Y.G. Song, S.P. Yun Korea Atomic Energy Research Institute (KAERI), Gyeongbuk, Republic of Korea
	Funding: This work has been supported through KOMAC (Korea Multi-purpose Accelerator Complex) operation fund of KAERI by MSIP (Ministry of Science, ICT and Future Planning). For the purpose of the ion beam irradiation, especially for helium beam application to semiconductor industry, an ion beam RFQ is under development at KOMAC (Korea Multi-purpose Accelerator Complex). The output energy of the RFQ is determined to be 1 MeV/n, which corresponds to 4 MeV in helium beam case, in consideration of the penetration depth in the silicon substrate. The RFQ is a four-vane type and will be fabricated through vacuum brazing technique. The RF power of 130 kW at 200 MHz will be provided to the RFQ by using a solid-state RF amplifier through two coaxial RF couplers with coaxial RF windows. The details of the RFQ development including some design features and fabrication methods will be given in this paper.
