MOSFET-based HTS flux pump / Jurčo, Róbert (CERN ; Charles U.) ; Vaskuri, Anna (CERN) ; Curé, Benoit (CERN) ; Dudarev, Alexey (CERN) ; Mentink, Matthias (CERN)
We have developed a high-temperature superconducting (HTS) flux pump using high-power metal-oxide-semiconductor field-effect transistors (MOSFETs) for switching. For its primary coil, two commercial transformers are utilized, each consisting of two copper coils wound on a single iron core, which enables changing the load current over primary current ratio (101 or 194) between the primary and secondary coils.

Design and Manufacturing of an HTS Helical Undulator Demonstrator for Compact FELs / Richter, S C (CERN ; KIT, Karlsruhe) ; Ballarino, A (CERN) ; Bernhard, A (KIT, Karlsruhe) ; Müller, A S (KIT, Karlsruhe)
Among all superconducting undulator geometries, a helical undulator provides a very compact geometry and further is more effective in producing synchrotron radiation, providing circularly polarized photons, which are widely usable for synchrotron radiation users. These characteristics make it a very attractive option for realizing more compact free-electron lasers, requiring a combination of short-period and high-field undulators to produce coherent light up to X-rays.

The EuCARD2 Future Magnets Program for Particle Accelerator High-Field Dipoles: Review of Results and Next Steps / Rossi, Lucio (CERN) ; Badel, Arnaud (IUT, Grenoble) ; Bajas, Hugues (CERN) ; Bajko, Marta (CERN) ; Ballarino, Amalia (CERN) ; Barth, Christian (Geneva U.) ; Betz, Ulrich (SIS GmbH) ; Bottura, Luca (CERN) ; Broggi, Francesco (LASA, Segrate) ; Chiuchiolo, Antonella (CERN) et al.
The EuCARD2 collaboration aims at the development of a 10 kA-class superconducting, high current density cable suitable for accelerator magnets, to be tested in small coils and magnets capable to deliver 3-5 T when energized in stand-alone mode, and 15-18 T when inserted in a 12-13 T background magnet. REBCO tape, assembled in a Roebel cable, was selected as conductor. [...]

HTS Accelerator Magnet and Conductor Development in Europe / Rossi, Lucio (LASA, Segrate ; Milan U. ; CERN) ; Senatore, Carmine (U. Geneva (main))
In view of the preparation for a post-LHC collider, in 2010 the high-energy physics (HEP) community started to discuss various options, including the use of HTS for very high-field dipoles. Therefore, a small program was begun in Europe that aimed at exploring the possibility of using HTS for accelerator-quality magnets. [...]
