In Japan, National Institutes for Quantum Science and Technology (QST) has the responsibility to develop nine toroidal field (TF) coils, each of which consists of a winding pack (WP) and coil case for the ITER project. The WP consists of seven double-pancakes (DPs), which consist of conductors inserted into D-shaped radial plates (RPs). Although a WP is significantly large (14 m high and 9 m wide), the position of the current center line of the WP must be controlled within a few millimeters. Therefore, numerous technical challenges arose in DP and WP manufacturing. Herein, in the RP manufacturing, the optimization of welding and machining procedures, and accurate manufacturing techniques were established. Subsequently, all RPs were fabricated around the flatness errors of 1 mm from the nominal. In cover plate (CP) welding, the welding procedure was optimized so that a good DP flatness after CP welding was achieved. In the WP insulation, by developing a method to insulate a WP while applying compression, the dimensions within errors of a few milli-meters is achieved in all of WPs. Consequently, all nine WPs were successfully completed for TF coils in Japan in March 2022.

“…The standard ASTM D 3039 was developed to evaluate tensile properties of discontinuous fiber or discontinuous fiber reinforced composites with a rectangular sample. However, double-bell specimens in accordance with ASTM D 638, which were developed to test tensile properties of plastic materials, have been widely used [21,22]. The ILSS was tested in accordance with ASTM D 2344.…”

Abstract. High field superconducting magnets need strong non-superconducting components for structural reinforcement. For instance, the ITER magnet system (MS) consists of cable-in-conduit conductor, coil case, magnet support, and insulating materials. Investigation of mechanical properties at magnet operation temperature with specimens machined at the final manufacturing stages of the conductor jacket materials, magnet support material, and insulating materials, even the component of the full-size conductor jacket is necessary to establish sound databases for the products. In China, almost all mechanical property tests of structural materials for the ITER MS, including conductor jacket materials of TF coils, PF coils, CCs, case material of CCs, conductor jacket materials of Main Busbars (MB) and Corrector Busbars (CB), material of magnet supports, and insulating materials of CCs have been carried out at the Technical Institute of Physics and Chemistry (TIPC), Chinese Academy of Sciences (CAS). In this paper, the mechanical property test facilities are briefly demonstrated and the mechanical tests on the structural materials for the ITER MS, highlighting test rigs as well as test methods, are presented.

“…The dose limits for the system that is currently being used in Nb 3 Sn model (CT101) should be characterized. Alternative resins as cyanate ester, used in ITER [15], show improved radiation resistance by about one order of magnitude and could be incorporated if CT101 does not provide adequate margin with respect to the expected radiation levels.…”

In this paper we outline the present status of the design studies for the high luminosity LHC, focusing on the choice of the aperture of the inner triplet quadrupoles. After reviewing some critical aspects of the design as energy deposition, shielding, heat load and protection, we present the main tentative parameters for building a 150 mm aperture Nb 3 Sn quadrupole, based on the experience gathered by the LARP program in the past several years.Presented at the Applied Superconductivity Conference 2012 (ASC 2012) 7-12 October 2012, Portland, OregonGeneva, Switzerland CERN-ATS-2013-018January 2013 > REPLACE THESE LINES WITH YOUR PAPER ID NUMBER, E.G., AB-02 (DOUBLE-CLICK HERE) < Abstract-In this paper we outline the present status of the design studies for the high luminosity LHC, focusing on the choice of the aperture of the inner triplet quadrupoles.
