	RF power couplers for half wave resonators are under development for the Rare Isotope Science Project (RISP) in Korea. It is required to deliver up to 6 kW RF power at 162.5 MHz to the HWR in CW mode. The RF coupler is a coaxial capacitive type using a disc type ceramic window. Design studies of 2nd prototype HWR RF coupler are presented.

	RF power coupler prototypes have been conditioned for a heavy ion accelerator of the Rare Isotope Science Project (RISP) in Korea. The RF couplers operate for 162.5 MHz half-wave resonators at 6 kW RF power. The RF couplers are a 50-Ohm coaxial structure with a disk type ceramic window at room temperature. The control system using Labview software supported automatic process for RF conditioning, data acquisition and interlock system. The conditioning system and the result of conditioning of RF coupler are presented in this paper.

	We developed and tested an C-band beam position monitor with position resolution of nano meter in ATF2. The C-band BPM was developed for the fast beam feedback system at the interaction point of ATF in KEK, which C-band beam position monitor called to IPBPM (Interaction Point Beam Position Monitor). The developed IPBPM was measured 26nm with 30% of nominal beam charge of ATF. From the measured beam position resolution, we can expected to 8nm beam position resolution with nominal ATF beam charge condition. In this talk, we will described about the development of IPBPM and the beam test results of nano meter level beam position resolution.

THPMB029	Simultaneous Two Beam Acceleration Lattice Design Study for the Post Linear Accelerator of RISP	3294
	S.W. Jang KNU, Deagu, Republic of Korea E.-S. Kim Korea University Sejong Campus, Sejong, Republic of Korea
	The Rare Isotope Science Project, RISP, is the research complex by using heavy ion accelerator, which RISP research complex consists of front-end system, super conducting linear accelerator(SCL), ISOL system, In-fight system. The original purpose of post linear accelerator was for the alternative acceleration of stable driver beam from ECR ion source and unstable rare isotope beam from ISOL system. The new concept of acceleration method by using post accelerator lattice was studied to get more benefits. The idea was the simultaneous acceleration of stable driver beam and RI beam by using the average A/q value of post accelerator lattice. For the simultaneous two beam acceleration study, we used two ion beams the first one was 58Ni+8 and the other one was 132Sn+20. The beam dynamics simulation was performed by TRACK and TraceWin codes. In this poster, we will describe the results of beam dynamics study for the simultaneous two beam acceleration of the post linear accelerator of RISP.

	The Korea Heavy Ion Medical Accelerator (KHIMA) project of the Korea Institute of Radiological and Medical Sciences (KIRAMS) has developed heavy ion medical accelerator. The injector system of the accelerator for the KHIMA project is composed of a low energy beam transport line (LEBT), radio frequency quadrupole (RFQ), interdigit H-mode drift tube linac (IH-DTL), and medium energy beam transport line (MEBT). The IH-DTL is designed with KONUS beam dynamics, and KONUS indicates a combined 0˚ structure. Optimization aims are to increase the quality of the beam and to reduce the beam loss. KONUS beam dynamics design and multi-particle tracking simulations of the IH-DTL with LORASR and TraceWIN code are performed.

	RISP control system uses the EPICS real time distributed control system, which is software framework for stable operation of the accelerator. The output signal from all machines and devices must be archived by EPICS framework, and optimized signal archiver system is needed for each accelerator facility. Signal archiver method using the EPICS framework has three significant ways. First is the classic channel archiver using the file base method and the second is the RDB archiver using the relational database. But classic channel archiver has a problem that the index file containing information of data block corresponding PV data mismatch with real data. Also, there is a problem in the performance of file I/O in RDB archiver. SLAC has developed archiver appliance utility to resolve these problems, and the usage of archiver appliance in EPICS community has gradually increased. RISP choose the archiver appliance to also signal archiver solution. However, archiver appliance is not optimized for our RISP heavy-ion accelerator control system. Thus, we will develop the customized signal archiver system for RISP heavy-ion accelerator control system.
