Аннотация:

The Institute for Basic Science (IBS), located in Daejeon, Korea, was established in 2011 by the Korean government. IBS has 28 Research Centers, one of which is the Rare Isotope Science Project (RISP). The accelerator complex for RISP was named RAON, which is a Korean word meaning “joy” or “happiness”. The goal of RISP is to produce a variety of stable and rare isotope beams which can be used in a variety of basic scientific research and applications. The RAON can deliver ions from protons to uranium. Proton and Uranium beams are accelerated up to 600 MeV and 200 MeV/u, respectively. The RAON will produce isotopes by using both In-Flight (IF) fragmentation and Isotope Separation On-Line (ISOL) methods. The IF system uses a driver linac which consists of superconducting ECR ion sources, a low energy beam transport (LEBT) section, a 300 keV/u RFQ, a superconducting (SC) linac, a medium energy beam transport (MEBT) section for a 400 kW in-flight fragmentation facility. The ISOL system uses a proton cyclotron as a driver, which accelerates protons to 70 MeV at 1 mA for ISOL facility. The ISOL facility uses an SC linac for post-acceleration of rare isotopes up to about 18.5 MeV/u, while the SC linac of IF facility is capable of accelerating uranium beams up to 200 MeV/u at 8 pμA.

There are seven experimental systems that are under construction, which include KOBRA, LAMPS, MMS, CLS, muSR, NDPS and BIS. The RAON User Liaison Center is established to facilitate the communication between the RISP and the outside users who will use the seven experimental systems. There is also an organization called the “RAON User Association” for promoting the use of the RAON among the users. We welcome participation of international users to the RAON User Association and the RAON User Liaison Center. The presentation will discuss the present status of RAON and its experimental systems and would like to promote international collaboration.
