Electromechanical investigations and quench experiments on sub-size HTS cables for high field EU-DEMO Central Solenoid

The aim of this thesis is to investigate the mechanical and thermal behaviour of HTS coated conductor cables for EUROfusion DEMO magnets. One of the issue in large HTS magnets is the safety against a quench. A quench is a sudden thermal runway in which the ...

Surface Susceptibilities as Characteristic Models of Reflective Metasurfaces

Karim Achouri, Shourya Dutta Gupta, Ville Tuovi Tiukuvaara

While metasurfaces (MSs) are constructed from deeply subwavelength unit cells, they are generally electrically large and full-wave simulations of the complete structure are computationally expensive. Thus, to reduce this high computational cost, nonuniform ...

The Upper Bound of the Speed of Propagation of Waves along a Transmission Line

Farhad Rachidi-Haeri, Marcos Rubinstein

According to theory, once certain conditions are fulfilled, current and voltage pulses propagate along ideal transmission lines with the speed of light. One can reach such a conclusion only when the conductors are assumed to be perfectly conducting, which ...

Conductor Performance of CCCN3, CCCN4 and CCCN5 Samples for ITER CC Coils

Pierluigi Bruzzone, Kamil Sedlák, Boris Stepanov, Yu Wu, Fang Liu

The conductor for the ITER Correction Coils (CC) is manufactured in China and is tested in the SULTAN facility. The third China CC conductor for the qualification SULTAN test sample (CCCN3) was prepared from a 200 m long CC conductor unit length (Phase II) ...

Examination of Nb3Sn Conductors for ITER Central Solenoids

Pierluigi Bruzzone, Kamil Sedlák, Boris Stepanov

The performance of two Nb3Sn conductors for the ITER central solenoids was tested. The current sharing temperatures (T-cs) were measured over 17 050 electromagnetic cycles, including four thermal cycles between 4.2 K and room temperature. T-cs declined alm ...

Examination of Japanese Mass-Produced Nb3Sn Conductors for ITER Toroidal Field Coils

Pierluigi Bruzzone, Boris Stepanov

The performances of six Nb3Sn conductors for the ITER Toroidal Field coils were tested. Four of them showed similar degradation rates of their current sharing temperatures T-cs over 1,000 electromagnetic cycles. By contrast, two of them showed sharp T-cs d ...

Test Result of a Full-Size Nb3Sn Conductor Developed for the ITER TF Coils

Pierluigi Bruzzone, Boris Stepanov

The Japan Atomic Energy Agency (JAEA) developed ITER TF Nb3Sn conductors that fulfill ITER requirements and has commenced fabricating the conductors to be used in the ITER TF coils. As a qualification of conductor fabrication, two full-size conductor sampl ...

Qualification tests for ITER TF conductors in SULTAN

Pierluigi Bruzzone, Rainer Wesche, Boris Stepanov

From February 2007 to May 2008, 18 short length conductor sections have been tested in SULTAN for design verification and manufacturer qualification of the ITER Toroidal Field (TF) conductor. The test program is focussed on the current sharing temperature, ...

Test results of a large size, forced flow Nb3Sn conductor, based on a design alternative to the cable-in-conduit

Pierluigi Bruzzone, Rainer Wesche, Boris Stepanov

An R&D program at CRPP investigates the design of large size Nb3Sn conductors, with the aim to improve the effectiveness and hence the cost of large size, force flow conductors. A design based on a solder filled flat cable, by react wind method, is selecte ...
