3D-printed Ka-band Antenna Based on Stereolithography

Juan Ramon Mosig, Tomislav Debogovic, Maria Garcia Vigueras, Joana Rita Alves dos Santos Silva

This paper presents a circularly-polarized dual-band antenna for Ka-band satellite communications which operates simultaneously in both civil and military downlink (17.7-21.2 GHz) and uplink (27.5-31 GHz) bands. The antenna is composed of a metallic ridged ...

Exploratory Topology Modelling of Form-Active Hybrid Structures

Mark Pauly, Anders Holden Deleuran

The development of novel form-active hybrid structures (FAHS) is impeded by a lack of modelling tools that allow for exploratory topology modelling of shaped assemblies. We present a flexible and real-time computational design modelling pipeline developed ...

Analysis of the CICC Performance Through the Measurement of the Thermal Strain Distribution of the Nb-3 Sn Filaments in the Cable Cross Section

Pierluigi Bruzzone, Ciro Calzolaio

The knowledge of the thermal strain distribution of the Nb3Sn filaments in a cable in conduit conductor (CICC) cross section is a key parameter in understanding the cable performance evolution when it undergoes electromagnetic (EM) cyclic loading. A CICC i ...

Irreversible Degradation in Nb3Sn Cable in Conduit Conductors

Ciro Calzolaio

One of the biggest goals for the international thermonuclear experimental reactor (ITER) is the steady state operation. For this reason all its coils will be superconducting and Nb3Sn material is used for both the toroidal field (TF) and the central soleno ...

Transverse heat transfer coefficient in the dual channel ITER TF CICCs Part I: Analysis of steady state temperature profiles resulting from annular heating

Two ITER IF dual channel Cable-in-Conduit Conductors (CICCs) have been tested in the SULTAN test facility. The samples were heated either by foil heaters mounted on the outside of the conductor jacket or by induced AC losses. The steady-state temperature r ...

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 ...

A critical review of coupling loss results for cable-in-conduit conductors

Pierluigi Bruzzone, Boris Stepanov

AC loss curves measured for the same conductors at SULTAN (CRPP) and at University of Twente (UT) in higher and respectively lower frequency range are compared to draw consistent results. From the unified curves, the coupling time constant (n tau) to be us ...
