  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.

  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.
