TL;DR: In this article, the results of measurements conducted at the neutron fluxes of nuclear reactors have demonstrated the operability of the sensors up to high neutron fluences of F > 1018n cm−2 that exceeds the maximum one for the locations of steady state sensors in ITER over its total lifetime.

TL;DR: In this paper, strong dipole permanent magnet models for various kinds of accelerator applications are under development at NIRS and field strengths exceeding 4 Tesla in the magnet gap are achieved by an extended Halbach type magnet configuration.

TL;DR: In this article, the authors discuss the principles of designing the magnetic measurement instrumentation based on the application of steady-state radiation-resistant semiconductor Hall sensors, and present the results of the instrumentation's application for ex-vessel magnetic field measurement on JET reactor during the latest deuterium campaign, and the prospects of further enhancement in magnetic diagnostic accuracy and reliability.

TL;DR: In this paper, it was shown that a permanent dipole magnet exceeding a typical permanent magnet more than by factor 3 is possible, and a new challenge is to conceive such magnet for an accelerator application where time dependent alternating field is often requested.

TL;DR: In this paper, Bolshakova et al. presented a Hall Sensor-Based Device for Magnetic Field Diagnosis at Fusion Reactors (HSD-FRE) at the National Technical University of Athens.
