Abstract Neutron activation dosimetry is the primary method for the determination of the neutron flux or fluence, and in general, it is sensitive to the thermal and resonance energy ranges (radiative capture reactions– $$(n,\gamma )$$ ( n , γ ) re

Niobium is a dosimeter used to characterize fast-neutron reaction rates to monitor nuclear reactor vessels. Its characterization is based on the activity of 93mNb resulting from the 93Nb(n,n’) activation reaction. The decay of 93mNb results mainly

Publikováno v: IEEE Transactions on Nuclear Science. 67:552-558

We have developed a Fabry–Perot extensometer that is able to operate at high temperature (up to 400 °C), for in pile experiments in material testing reactor, under high neutron and gamma flux. For that purpose, we have revised the basic scheme of
