  A-BNCT accelerator is being developed as a proton accelerator with a high beam current of 50 mA for effective cancer therapy. Drift tube linac (DTL) with the length of 4.5 m is composed of 1 tank and 48 drift tubes (DTs). Proton beam is accelerated from 3 MeV to 10 MeV. Electromagnetic quadrupoles (EMQs) are inserted into every DT for transverse focusing. Slug tuners and post couplers (PCs) are used for accelerating field stabilization and resonant frequency tuning, respectively. The beam dynamics and engineering design for the DTL are performed for effective beam acceleration, and the design results are in detail presented.

  KBSI (Korean Basic Science Institute) has been developed a compact accelerator system for generation of fast neutron by 2.7 MeV/u of lithium beam. The facility consists of 28 GHz SC-ECR ion source, LEBT, RFQ and DTL. The developed RFQ accelerator provides lithium ion beam from 12 keV/u to 500 keV/u with 98.88 % of high transmission rate at 165 MHz of operation frequency. RF power system for RFQ accelerator has been developed to provide sufficient RF power into RFQ cavity. which consists of LLRF system for control, 5 KW of SSPA as IPA, tetrode tube amplifier as FPA, coaxial transmission line and circulator for protection from reflection power provides 100 kW at operation frequency with CW mode, In this paper, we discuss about development of RF system and performance test in detail.

  A accelerator for Boron Neutron Capture Therapy (BNCT) based on proton linac has been developed as a domestic project. The accelerator system consists of duo plasmatron as an ion source, low energy beam transport (LEBT), radio frequency quarupole (RFQ) accelerator, drift tube linac (DTL). In order to achieve beam power of 50 kW, the required beam intensity and energy are 50 mA and 10 MeV, respectively. Since high duty rate provides high efficient medical treatment, the design of the cw RFQ has been investigated to accelerate proton beam from 50 keV to 3 MeV with beam intensity of 60 mA. In this paper, beam dynamics and design of the RFQ are presented in detail.
