  This study shows the development and performance assessment of a novel set-up
that enables the research of structural materials for fusion reactors, by
making possible simultaneous application of temperature (up to 450$^{\circ}$C)
and magnetic field (close to 0.6 T) during irradiation experiments. These
aspects become critical as structural materials in fusion reactors are exposed
to intense radiation levels under the presence of strong magnetic fields.
Moreover, material microstructural could be modified by radiation-induce
propagating defects, which are thought to be sensitive to magnetic field. The
device has three main components: magnetic closure, sample holder with
integrated heater, and radiation shield. It is provided with a thermal shield
to prevent other elements of the device to heat up and fail. A mapping of the
magnetic flux in the region where sample and heater are located has been
modeled by finite elements simulation software and correlated with magnetic
measurements
