Sn-NbTi joint used for connecting CS (NbSn) and current feeder (NbTi). The terminal joints are placed at the top and the bottom of the CS systems. CS modules located at middle position of CS system need the lead extension from the modules to the terminal joint. The joint resistance measurement of terminal joint was performed in the test facility of National Institute for Fusion Science. The joint resistance was evaluated by the operating current and the voltage between both ends of the terminal joint part. Test results met the requirement of JT-60SA magnet system. The structural analysis of the lead extension and its support structure was conducted to confirm the support design. In this paper, the results of resistance test of joint and the structural analysis results of lead extension are reported.

While holding coil current of 20 kA, the magnetic fields were varying slightly with several long time constants. The range of the time constant was from 17 sec to 571 sec, which was much longer than the time constant derived from the measurement using the short straight sample. To validate the measurements, the magnetic fields of the model coil were calculated using the calculation model representing the positions of NbSn strands inside the CIC conductor. The calculations were in good agreement with the measurements. Consequently, the validity of magnetic field measurements was confirmed.

Times Cited Count：25 Percentile：72.08(Engineering, Electrical & Electronic)Central Solenoid (CS) of JT-60SA are designed with the NbSn cable in conduit conductor. CS model coil (CSMC) was manufactured by using the real manufacturing jigs and procedure to validate the CS manufacturing processes before starting mass production. The dimensions of the CSMC are the same as real quad-pancake. The cold test of the CSMC was performed and the test results satisfied the design requirements. These results indicate that the manufacturing processes of the JT-60SA CS has been established. In this paper, the development and the validation of the CS manufacturing processes are described.
copper nitrite reductase; Involvement of the unique N-terminal region in the interprotein electron transfer with its redox partnerFukuda, Yota*; Koteishi, Hiroyasu*; Yoneda, Ryohei*; Tamada, Taro; Takami, Hideto*; Inoue, Tsuyoshi*; Nojiri, Masaki

Times Cited Count：16 Percentile：46.83(Biochemistry & Molecular Biology)The crystal structures of copper-containing nitrite reductase (CuNiR) from the thermophilic Gram-positive bacterium 
HTA426 and the amino (N)-terminal 68 residue-deleted mutant were determined at resolutions of 1.3
and 1.8, respectively. Both structures show a striking resemblance with the overall structure of the well-known CuNiRs composed of two Greek key 
-barrel domains; however, a remarkable structural difference was found in the N-terminal region. The unique region has one -strand and one 
-helix extended to the northern surface of the type-1 copper site. The superposition of the CuNiR model on the electron-transfer complex structure of CuNiR with the redox partner cytochrome 
in other denitrifier system led us to infer that this region contributes to the transient binding with the partner protein during the interprotein electron transfer reaction in the system. Furthermore, electron-transfer kinetics experiments using N-terminal residue-deleted mutant and the redox partner, cytochrome , were carried out. These structural and kinetics studies demonstrate that that region is directly involved in the specific partner recognition.

Times Cited Count：12 Percentile：60.72(Materials Science, Multidisciplinary)The effect of oxygen potential on the sintering behavior of MgO based heterogeneous fuels containing (Pu,Am)O was experimentally investigated. Sintering tests in various atmospheres, i.e. air, moisturized 4%H
-Ar, and 4%H-Ar atmosphere, were carried out. The sintering behavior was found to be significantly affected by the oxygen potential in the sintering atmosphere. The sintered density decreased with decreasing oxygen potential. The (Pu,Am)O phase sintered in a reductive atmosphere had hypostoichiometry. The aggregates of the (Pu,Am)O phase sintered in the reductive atmosphere grew, in comparison with those in the oxidizing one. The sintering mechanism was discussed in terms of the difference in sintering behavior of (Pu,Am)O and MgO.
