H4.00001: Introduction to Korean Accelerator Science and Activities in Industrial Accelerators Invited Speaker: Won Namkung After 20 years of the first large-scale accelerator in Korea, the Pohang Light Source (PLS) of 2.0 GeV at POSTECH, its upgrade (PLS-II) is now under commissioning with energy of 3.0 GeV. The users' service for synchrotron radiation is scheduled in April 2012. There are five big accelerator projects in various stages of construction, namely a high-intensity proton linac of 100 MeV, the PAL-XFEL of 10-GeV, a carbon therapy cyclotron of 400 MeV/u, and rare isotope accelerators for isotope separator on-line (ISOL) and In-flight Fragmentation (IFF). There are also strong demands for industrial uses of accelerators, especially in sterilization applications. In this paper, we report the current status of accelerator projects and its science in Korea, along with a brief review of accelerator R{\&}D going back to the early 1960s at universities.

H4.00002: Korean Contribution to the Progress of Science and Humanity Invited Speaker: Dong-Pil Min Science has problems yet to solve those global issues as the climate change, nuclear waste, water pollution, etc, although science and technology have been major contributors to human progress and will continue to open new doors to economic, medical and environmental advancement. Furthermore the benefits of scientific knowledge are not readily and evenly allocated across the globe. Korea will contribute to the progress of science by providing cooperative opportunities of the future research on the pure and applied scientific issues. Recently Korea launches a project of construction of the rare isotope accelerator, KoRIA, and Institute of Basic Science. Plans are set also to help develop the appropriate technology for developing countries. In this talk two aspects of science policy of Korean government are introduced, which are related to the accelerator KoRIA and to the thought on the establishment of Common Technology Platform. The former is to help the world science society for the expansion of our knowledge on the universe and matter, while the latter is to help the transfer of our knowledge to make our planet more flat.

H4.00003: Synchrotron Radiation and X-ray FEL Projects in Korea Invited Speaker: M.H. Cho There are two on-going major projects in Pohang Accelerator Laboratory (PAL), the PLS-II light source upgrade and the construction of PAL-XFEL facility. PLS-II is a new light source upgraded from PLS(Pohang Light Source) which had been operated for 16 years from 1995 and shut down in Dec. 2010. The performance will be improved from ``18.9 nm-rad, 2.5 GeV, and 200 mA'' to ``5.8 nm-rad, 3 GeV, and 400 mA'' using three superconducting RF cavities. The old storage ring has been completely dismantled and new DBA ring has been re-installed in the same tunnel within 6 months, and is under commissioning now. The unique feature of PLS-II is the compact employment of 20 insertion-devices including 14 in-vacuum undulators. The PALXFEL is a 0.1-nm hard X-ray FEL construction project started in 2011 and to compete in 2014 with a total budget of 400 M{\$}. The PAL-XFEL is designed to have hard X-ray undulator lines at the end of 10-GeV linac, and a dog-leg branch line at 2.65 GeV point for a soft X-ray undulator line simultaneously and independently from hard X-ray FEL undulator line. The overview of two projects with current status is presented. [Preview Abstract] |
