“…This joint is a butt joint, similar to the one used in the CS Model Coil (CSMC) [6], [7]. A special development has been undertaken by the ITER US Domestic Agency, who will be in charge of the procurement of the CS, to demonstrate that this type of joint is matching the operating conditions of a CS module [8], in particular the fatigue constraints.

The Central Solenoid (CS) of the ITER tokamak has to provide the flux variation needed to induce the plasma current and to shape the field lines in the divertor region. It is designed as a stack of 6 identical coils, independently power supplied. Repulsing forces arising between the coils during a scenario are withstood by a precompression structure installed around the coils. Studies were carried out to simplify the winding manufacture, to optimize the precompression structure and procedure, to optimize the stack assembly of the 6 coils and the assembly of the central solenoid inside the tokamak which allows withdrawal from the machine, while meeting the ITER design criteria and in particular the Magnet Structural Design Criteria (static and fatigue).

“…Because of its dangerous nature, this transient in CICCs has been deeply investigated both from experimental [114,[119][120][121][122][123][124] and numerical [101,106,110,[125][126][127][128][129][130][131][132][133][134][135] points of view.…”

“…The typical features of a quench transient in a CICC, with reference to the data collected during the latest ITER CS Insert (CSI) test campaign in 2015 [114], see Figure 4.38 for the sensors location, are reported here. This case, although quite complex, has been chosen as a reference because the conductor was very well instrumented in terms of TH and electrical measurements:…”

Superconductors enable many large-scale electric applications, both current and under research, with a high potential to cause important breakthroughs in human development. These are, for example, the reduction of emissions responsible for the climate crisis through energy generation (fusion and offshore wind turbines), electric transportation (electric and hybrid-electric airplanes or sea vessels), and energy-efficient electric networks (power-transmission cables and transformers). Superconductors also enable novel medical instruments, such as (high-field) magnetic resonance imaging (MRI) and accelerators for ion cancer therapy. Last but not least, superconducting magnets made it possible to conduct some of the largest experiments in fundamental research in the world, involving particle accelerators and detectors, such as the large hadron collider (LHC).

“…The CS design originally had a butt joint as the baseline compact joint [1]. A soldered version of a lap joint was dismissed due to doubling of the cooling lines for cooling the joint and significant increase (basically double) of the joint volume.…”

Abstract-The ITER Central Solenoid has 36 interpancake joints and 12 bus joints in the magnet. The joints are required to have resistance below 4 nOhm at 45 kA at 4.5 K. The interpancake joints will have to withstand a significant cyclic tensile strain during ITER operation. The joints are located at the OD of the magnet embedded in the winding pack and therefore need to be compliant with the rest of the winding pack to avoid excessive stress.The US ITER Project Office is carrying out a program for joints development in order to establish fabrication process and also characterize electrical and mechanical performance of the joints in a special Joint Test Apparatus.Status of the joint development and test results are presented and discussed in the paper.
