TI - Field tuning of the 1 MeV/n RFQ at KOMAC J2 - Proc. of IPAC2021, Campinas, SP, Brazil, 24-28 May 2021 CY - Campinas, SP, Brazil T2 - International Particle Accelerator Conference T3 - 12 LA - english AB - A 1 MeV/n Radio-frequency Quadrupole (RFQ) is under development at Korea Multi-purpose Accelerator Complex (KOMAC), the purposes of which are swift ion beam irradiation and compact neutron source. The RFQ was designed to accelerate ions with mass to charge (A/q) ratio up to 2.5. The designed peak current was 10 mA with 10% duty ratio. The RFQ is four vane structure resonated at 200 MHz. It has total 40 frequency tuners. There are no dipole rods and resonant coupling plate because the mode separation was large enough and the length of the RFQ was only two times of the wavelength. In this paper, the development status and field tuning results of the 1 MeV/n RFQ are presented.
