To meet the performance test of the International Thermonuclear Experimental Reactor correction coil conductors, a 50-kA superconducting transformer has been manufactured, which allows rating of test samples under different operating conditions at the Institute of Plasma Physics of the Chinese Academy of Sciences (ASIPP). This transformer system is made up of two concentric layer-wound superconducting solenoids with the primary inside the secondary. The 50-kA secondary winding consists of 4-turn rectangular cable-in-conduit conductor type. This paper describes the design and manufacture techniques of the 50-kA transformer, including a secondary conductor. The secondary terminal design and manufacture are also discussed. Finally, the first test results of the 50-kA transformer are presented.

“…In the past decades, a number of SCTs are developed for superconducting cable testing. For example, a 50 kA SCT is used as a current source at the SULTAN test facility at the Centre de Recherches en Physique des Plasma (CRPP) in Switzerland [3] and another SCT, which was designed to 50 kA and tested up to 38 kA, is used at FRESCA, the CERN cable test facility in Switzerland [4], [5]. The Lawrence-Berkley National Laboratory (LBNL) developed a 50 kA SCT and tested up to 28 kA [6].…”

A facility capable of testing superconducting cables with current of tens of kA is essential for the development of large superconducting magnets. A superconducting transformer (SCT) is a suitable choice as a high DC current source for testing superconducting cables. In this work, we will present our experimental results of a SCT up to output current of 45 kA. The properties of this SCT is characterized at 4.2 K. Its behaviors during quenches at different current levels are studied.

“…Initially designed as a graded solenoid with a 600 mm bore to host a single layer conductor sample, fed by a 10 kA direct power supply, SULTAN was upgraded into a split solenoid with a 100 mm access gap and a superconducting transformer to feed the straight, short length sample with current up to 45 kA [2]. Further upgrades included a new current source up to 100 kA in 1996 [3] and pulsed field coils for ac loss and transient stability in 2001 [4].…”

All the ITER superconductors are tested as short length samples in the SULTAN test facility at CRPP. Eighteen TF conductor samples with small layout variations were tested since February 2007 with the aim of verification of the design and qualification of the manufacturers. The sample assembly and the measurement techniques at CRPP are discussed. Starting in 2010, another test facility for ITER conductors, named EDIPO, will be operating at CRPP to share with SULTAN the load of the samples for the acceptance tests during the construction of ITER.
