Design and Procurement of the European Dipole (EDIPO) Superconducting Magnet

Abstract-A 45 T Hybrid Magnet System is being developed at the Nijmegen High Field Magnet Laboratory as part of the Nijmegen Center for Advanced Spectroscopy. The 45 T Hybrid Magnet System will be used in combination with far-infra-red light produced by a Free Electron Laser under construction directly adjacent to the High Field Magnet Laboratory. The superconducting outsert magnet will consist of three CICC coils wound on a single coil form, using Nb 3 Sn strands. A test program for strand and cable qualification is underway. The CICC will carry 13 kA and the coils will produce 12 T on axis field in a 600 mm warm bore. The nominal operating temperature will be 4.5 K maintained with forced-flow supercritical helium. The insert magnet will produce 33 T at 40 kA in a 32 mm bore consuming 20 MW, and will consist of four coils. The insert magnet will be galvanically and mechanically isolated from the outsert magnet. Complete system availability for users is expected in 2014. In this paper we will report on the conceptual design of the 45 T Hybrid Magnet System.

“…Digital Object Identifier 10.1109/TASC.2010.2043659 developed e.g., in the EDIPO project [6] and the Series-Connected Hybrid projects of the NHMFL [1]. More specifically, we require that the outsert magnet be stable against insert magnet trips, i.e., does not quench, which is a serious complication in a hybrid magnet.…”

“…T HE superconducting test facility EDIPO will provide a uniform DC field of 12.5 T over a length of 1 m for testing superconducting samples [1]. With the acronym EDIPO in this paper we will refer to the racetrack dipole main magnet (MM) and the superconducting transformer (TRAFO): the first is wound with cable-in-conduit conductors (CICC) whereas the second is wound with a SC cable.…”

EDIPO is the new 12.5 T superconducting test facility that is being installed at CRPP in Villigen, Switzerland. It will be placed beside the existing test facility SULTAN. The main purpose of both facilities is testing samples for the ITER project. EDIPO will provide a uniform high field region of 1 m, i.e. longer than SULTAN's ( 45 cm). EDIPO includes the main magnet and a superconducting transformer to power it with a current up to 100 kA in the test sample. The energy stored in the dipole is 16 MJ and in the undesired event of a quench this energy must be safely extracted. A Quench Detection System (QDS) is required to trigger the quench protection system for both the dipole and the transformer. This paper describes the overall QDS from the conceptual design, components, manufacture and commissioning as well as interactions with related systems.

“…T HE Europen Dipole (EDIPO) project (Table I, Figs. 1, 2, [1]) aims to build a high field magnet made of a pair of saddle-shape superconducting coils wound by Cable-In-Conduit Conductors (CICCs) with Nb3Sn strands. EDIPO is designed to produce a uniform ( 3% variation) dc field over a length inside a 100 mm 150 mm bore and to generate, with , a time-varying field of up to .…”

The aim of this paper is to present an up to date review of the status of the European DIPOle (EDIPO) project whose objective is to build a new facility to perform both DC and AC tests of large superconductor samples in high magnetic background field (up to 12.5 T). EDIPO was designed by EFDA, is being built by BNG (Babcock-Noell) and, once completed, it shall be installed near the existing SULTAN facility at the Paul-Scherer-Institute, (CRPP, Villigen, Switzerland). The results presented focus on the manufacture of the dummy coil (which is a 1:1 model of one of the EDIPO poles) that was completed in spring 2009. Details are given about the dummy coil winding results, coil reaction heat treatment, impregnation and acceptance tests. Moreover, a progress status is provided about the manufacturing of the other parts of the EDIPO magnet assembly, in particular with respect to the manufacturing of the test-well, AC coils, yoke sheets cutting and assembly, the outer cylinder production and welding (316 LN steel, 35 mm thick) and the coils ends preparation. Some results regarding the R&D studies are also reported about the winding trials carried out to improve the winding accuracy and the numerical simulations made to support coil winding (e.g. conductor spring back).
