Korean Facilities (5)

Pohang University of Science and Technology (POSTECH)

- The Pohang Light Source (PLS) at the Pohang Accelerator Laboratory(PAL) is a third-generation light source, the only synchrotron radiation facility in Korea, and the fifth machine of its kind in the world. In 1988, PAL was organized for the construction of the PLS. Ground-breaking was celebrated in 1991, and PLS construction was completed in 1994. In 1995, the PLS opened two beamlines to public users. The PLS was initially operated at 2GeV in 1995. Since 2002, the energy of the electron beam has been increased to 2.5GeV. The Pohang Light Source(PLS) was upgraded as the PLS-II in three years from 2009 to 2011. The electron beam energy was increased from 2.5 GeV to 3 GeV, and the beam current rose from 170 mA to 400 mA. The number of straight sections for the insertion devices increased from 10 to 20. - Two or three beamlines have been added each year for the past 20 years, and as of 2017 we have in total 34 beamlines in operation and 2 beamlines under construction. Since its opening in 1995, PAL has attracted 38,000 (and growing) individual users from domestic and around the world and produced 12,000 scientific articles in total. For last twenty years, PAL has contributed to remarkable growths not only in quantity but in quality of synchrotron research.

Austria / Self-standing

The idea of a bilateral Nuclear Magnetic Resonance (NMR) Center for solid and solution state spectroscopy arose through the collaboration between scientists of JKU and the University of South Bohemia in 2004. It was realized through a joint project within the ETC Austria - Czech Republic 2007-2013 programme of the European Union (EU) between the Johannes Kepler University Linz (JKU) and the University of South Bohemia in České Budějovice (USB) “Cooperative Regional Research Infrastructure for Molecular Science and Technology” (RERI-uasb).The NMR Center is co-financed with the European Union from the European Region Development Fund and operated jointly by both universities.

Centre of Excellence for Integrated Approaches in Chemistry and Biology of Proteins CIPKEBIP is a non-profit research institution. CIPKeBiP will connect the top available expertise, knowhow, and technology of Slovenian research laboratories in protein science, thus emphasizing biomedical relevance of the applied project (priority health and life sciences). The Centre is coordinated by the Department of Biochemistry and Molecular and Structural Biology at JSI, the leading edge of Slovenian biochemical science, and includes institutions from central and northeastern region of Slovenia as well as small, medium and large industrial entities. Using the Centre of Excellence grant as the start-up money we have established a research infrastructure and scientific platforms which enable us to:-identify molecular carriers and pathways underlying physiological and pathological processes.-monitor molecules, their position, transfer and transformations in biological processes.-characterize their biochemical and biophysical properties and structure.-and exploit the gained knowledge for commercial purposes. The platforms are: -High resolution and super-resolution light microscopy for visualization of molecules and their interactions in cells or in tissues and organisms.-Mass spectroscopy for analysis of protein composition in complex samples and analysis and identification of individual biological molecules and their modifications.-Protein and structure production platform for analysis of molecular mechanisms from biochemical to atomic resolution studies (3D crystal structures, kinetics of interactions and properties of biologically active molecules - proteins and small organic molecules).-Platform for development of biologically active organic molecules based on biological and chemical synthesis. -Computational analysis of complex biological and other experimental data with the purpose of descriptive and predictive modeling, knowledge extraction and integration, as well as optimization of experimental approaches and technological processes.The founding members of CIPKeBip are:- Jožef Stefan Institute- AciesBio d.o.o.- University of Ljubljana, Medical Faculty, Institute of Pathophysiology- University of Ljubljana, Biotechnical faculty- University Medical Centre Ljubljana- Jenko d.o.o.- University of Maribor, Medical Faculty- Institute of Public Health Maribor.

United Kingdom / University of Manchester

e-MERLIN is a unique astronomical facility, which provides radio imaging, spectroscopy and polarimetry with 10-150 milliarcsecond resolution and microJansky sensitivity at centimetre wavelengths. STFC and the University of Manchester now operate e-MERLIN under a contractual framework. The e-MERLIN upgrade includes new receivers (with improved sensitivity, wide frequency coverage, and greater flexibility) and a 210 Gb/s optical fibre network has been installed to connect each telescope to a powerful new correlator at Jodrell Bank Observatory. ‘First fringes’ with e-MERLIN were obtained in 2009. The first images with the full network were made in September 2010.e-MERLIN is an array of seven radio telescopes, spanning 217km, connected by a new optical fibre network to Jodrell Bank Observatory. In current rounds observations are limited to 512MHz/pol bandwidth. e-MERLIN will have a maximum instantaneous bandwidth of 4 GHz, giving a sensitivity of a few micro Jy/beam at its prime frequencies of 1,5 and 6 GHz. Together with the high resolution provided by the long baselines and the wide-field, spectroscopic and polarisation capabilities enabled by the new correlator, this will enable a wide range of new science programmes to be undertaken.

We report the synthesis of carbon nanotube (CNT) forests with a narrow diameter distribution based on Fe ion implantation method. By annealing the Fe-implanted SiO2/Si wafer in an Ar atmosphere at 800°C for 15 min, the Fe particles on the surface of SiO2 layer are successfully formed by the diffusion of Fe atoms from the SiO2 layer. Interestingly, the size distribution of Fe catalyst particles for Fe-implanted SiO2/Si wafers does not change with the prolonged annealing durations of up to 12 h. Using secondary ion mass spectroscopy and transmission electron microscopy (TEM), we confirmed that the implanted Fe atoms diffuse out of the SiO2 layer and form Fe particles on both the SiO2 surface and the interface between SiO2 and Si. The cross-sectional TEM images indicate that the Fe catalyst particles are anchored in the SiO2 layer, which limits the particles' mobility and results in an invariant catalyst size distribution for prolonged annealing durations. Therefore, we anticipate that implantation can be an efficient alternative catalyst preparation method for CNT forest growth which can solve various growth issues that are inherently caused by conventional physical vapor deposition method.

The diffusion properties of H+ in ZnO nanorods are investigated before and after 20 MeV proton beam irradiation by using 1H nuclear magnetic resonance (NMR) spectroscopy. Herein, we unambiguously observe that the implanted protons occupy thermally unstable site of ZnO, giving rise to a narrow NMR line at 4.1 ppm. The activation barrier of the implanted protons was found to be 0.46 eV by means of the rotating-frame spin-lattice relaxation measurements, apparently being interstitial hydrogens. High energy beam irradiation also leads to correlated jump diffusion of the surface hydroxyl group of multiple lines at ~1 ppm, implying the presence of structural disorder at the ZnO surface.

The proton beam intensity of a 100-MeV proton linac at the Korea Multi-purpose Accelerator Complex (KOMAC) was measured by an Au activation analysis using 197Au(p, pn)196Au and 197Au(p, p3n)194Au reactions to determine the accuracy and precision of beam intensity measurement using Gafchromic film dosimetry method. The target, irradiated by 100-MeV protons, was arranged in a stack consisting of Au, Al foils and Pb plates. The yields of produced radio-nuclei in Au foils were obtained by gamma-ray spectroscopy. The FLUKA code was employed to calculate the energy spectrum of protons onto the front surface of Au foils located at three different depth points of the target and also to investigate the condition of incident beam on the target. A good agreement was found between the beam intensity measurements using the activation analysis method at three different depth points of the target. An excellent agreement was also observed between the beam intensity measurements using the Au activation analysis method and the dosimetry method using Gafchromic film.
