Collective Flux Jumps observed in the Operation of the EDIPO Magnet

Pierluigi Bruzzone, Kamil Sedlák, Davide Uglietti, Boris Stepanov, Rainer Wesche, Stephen Alfred March

The tilted head race track coils of the EDIPO test facility are wound with cable-in-conduit conductors made by high current density Nb3Sn strands, Jc = 2400 A/mm2 at 12 T – 4.2 K. Since the commissioning of the coils, frequent voltage spikes were observed ...

Manufacture of ITER feeder sample conductors

Pierluigi Bruzzone, Bo Liu, Hongwei Li

The ITER feeders are the components that connect the ITER magnet systems located inside the main cryostat to the cryogenics, power-supply and control system interfaces outside the cryostat. The feeder busbars rely on the Cable-In-Conduit Conductor (CICC) d ...

UV-Cured Epoxy-Zno Composites: Preparation and Characterization

Federica Sordo, Marco Sangermano

Epoxy-ZnO composites are prepared via UV-induced cationic polymerization. Complete unsoluble materials are achieved after 10min of irradiation. Thermal analyses shows an increase of T-g in the presence of the ZnO attributable to a strong hindrance effect o ...

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 ...

Modeling of High-Frequency Electromagnetic Effects on an Ironless Inductive Position Sensor

Yves Perriard, Alessandro Danisi, Alessandro Masi

The ironless inductive position sensor (I2PS) is a five-coil air-cored structure that senses the variation of flux linkage between supply and sense coils and relates it to the linear position of a moving coil. In air-cored structures, the skin and proximit ...
