“…A standard tool in present days neutronics TBM mock-up experiments, see for example [2,3], is the application of activation foils to determine the spectral neutron flux density in selected positions in the mock-up. This information is an important experimental parameter for further analysis of the experiment as well as benchmarking of neutron transport codes and nuclear data against the experiment.…”

“…To improve the accuracy of those parameters which originate both from the cross section libraries and calculation codes, many experiments have been conducted through measuring neutron spectrum, reaction rate, and tritium production rate (TPR). [1][2][3][4] TPR is important in the design of fusion reactors. Thus, various integral experiments for TPR measurements have been done using (1) a self-irradiation method with a LiF thermoluminescence dosimeter, 5) (2) a liquid scintillation counting technique, [6][7][8][9][10] and (3) a Li-glass scintillator.…”

6 LiF small neutron detectors with an optical fiber have been used to measure 6 Li(n,)T reaction rate distributions at thermal research reactors and accelerator facilities. In the present study, we developed an experimental method for the measurement of tritium production rate (TPR) of 6 Li using this small detector in deuterium-tritium (D-T) neutron fields. Reaction rate measurements with the detector were conducted in the D-T neutron fields at the Fusion Neutronics Source (FNS) facility. From the results, we determined that this detector can be used to measure the TPR distribution in soft neutron spectrum fields such as in a Be assembly. It is difficult to obtain 6 Li(n,)T reaction rate separately in hard neutron spectrum fields such as in a Li 2 O assembly, because many kinds of charged particle production reactions need to be taken into consideration. However, a time-dependent reaction rate measurement method combined with the 6 LiF detector and the ZnS detector is effective to separate the 6 Li(n,)T reaction from other reactions even in a hard spectrum field, and it can be applied to the measurement of the TPR distribution accurately.
