The mission of korea superconducting Tokamak Advanced Research (ksTAR)project is to develop an advanced steady-state superconducting tokamak for establishing a scientificand technological basis for an attractive fusion reactor. Because one of the ksTAR mission is toachieve a steady-state operation, the use of superconducting coils is an obvious choice for themagnet system. The ksTAR superconducting magnet system consists of 16 Toroidal Field (TF) coils and14 Poloidal Field (PF) coils. Internally-cooled Cable-In-Conduit Conductors (CICC) are put into usein both the TF and PF coil systems. The TF coil system provides a field of 3.5 T at the plasmacenter and the PF coil system is able to provide a flux swing of 17 V-sec. The major achievement inksTAR magnet-system development includes the development of CICC, the development of a full-size TFmodel coil, the development of a coil system for background magnetic-field generation , theconstruction of a large-scale superconducting magnet and CICC test facility. TF and PF coils are inthe stage of fabrication to pave the way for the scheduled completion of ksTAR by the end of 2006.

Effect of CaO composition on oxidation and burning behaviors of AM50 Mg alloy

引用

Transactions of Nonferrous Metals society of China 2011年第A1期21卷 23-27页

作者： Jin-kyu LEE shae k.kim Advanced Material Division Korea Institute of Industrial Technology 7-47 Songdo-Dong Yeonsu-Gu Incheon 406-840 Korea

Oxidation and burning behaviors were studied for CaO added AM50 Mg composites which were manufactured by conventional melting and casting processes without sF6 protective gas. CaO added AM50 Mg composites show the stable oxidation resistance, while AMs0 Mg alloys show the poor oxidation resistance. The effects of CaO addition on the burning resistance under ambient, nitrogen and dry air atmospheres were examined for CaO added AM50 Mg composites. With increasing CaO addition, the burning temperature increases under ambient, nitrogen and dry air atmospheres. The burning temperatures of small test specimen under all conditions greatly increase even by 0.3% CaO （mass fraction） addition into AM50 Mg alloys.

A corrosion resistant CuNi cladding was deposited on sM45C (equivalent to AIsI1045) substrate by DC inverse arc welding. During the welding process, a three channel acoustic emission (AE) monitoring system was applied to detect the crack signals generating from both the cladding process and after cladding. Characteristics of the welding crack signal and noise signal had been analyzed systematically. Based on the record time of the signal, the solidification crack and delayed crack were distinguished. By two-dimensional AE source location, the crack position was located, and then investigated by scanning electron microscopy (sEM). Results showed that the AE system could detect the welding crack with high sensitivity and the two-dimensional source location could accurately determine the crack position. Microstructures of the cladding and heat affected zone (HAZ) were examined. Dendrites in the cladding and coarse grains in the HAZ were found.

Physical properties of sprayed antimony doped tin oxide thin films:The role of thickness

引用

Journal of semiconductors 2011年第5期32卷 10-17页

作者： A.R.Babar s.s.shinde A.V.Moholkar C.H.Bhosale J.H.kim k.Y.Rajpure Electrochemical Materials Laboratory Department of PhysicsShivaji UniversityKolhapur-416 004India Department of Materials science and Engineering Chonnam National University300 Yongbong-DongBuk-GuGwangju500-757South Korea

Transparent conducting antimony doped tin oxide （sb：snO2） thin films have been deposited onto pre- heated glass substrates using a spray pyrolysis technique by varying the quantity of spraying solution. The structural, morphological, X-ray photoelectron spectroscopy, optical, photoluminescence and electrical properties of these films have been studied. It is found that the films are polycrystalline in nature with a tetragonal crystal structure having orientation along the （211） and （112） planes. Polyhedrons like grains appear in the FE-sEM images. The average grain size increases with increasing spraying quantity. The compositional analysis and electronic behaviour of sb：snO2 thin films were studied using X-ray photoelectron spectroscopy. The binding energy of sn3ds/2 for all samples shows the sn^4＋ bonding state from snO2. An intensive violet luminescence peak near 395 nm is observed at room temperature due to oxygen vacancies or donor levels formed by sb^5＋ ions. The film deposited with 20 cc solution shows 70 % transmittance at 550 nm leading to the highest figure of merit （2.11 × 10^-3 Ω^-1）. The resistivity and carrier concentration vary over 1.22 × 10^-3 to 0.89 × 10^-3Ω cm and 5.19 ×10^20 to 8.52 × 10^20 cm^-3, respectively.
