Challenging neutron-capture cross-section measurements of small cross sections and samples with a very limited number of atoms require high-flux time-of-flight facilities. In turn, such facilities need innovative detection setups that are fast, have low sensitivity to neutrons, can quickly recover from the so-called $\gamma$-flash, and offer the highest possible detection sensitivity.

Multi-section fission ionization chamber for measurement of 239Pu(n,γ) reaction in fission tagging method
/ Perkowski, J (Lodz U.) ; Alcayne, V (Madrid, CIEMAT) ; Andrzejewski, J (Lodz U.) ; Cano-Ott, D (Madrid, CIEMAT) ; Gawlik-Ramięga, A (Lodz U.) ; Mendoza, E (Madrid, CIEMAT) ; Sánchez-Caballero, A (Madrid, CIEMAT) ; Sibbens, G (Geel, JRC) ; Vanleeuw, D (Geel, JRC) ; Aberle, O (CERN) et al.
The 239Pu(n,γ) reaction cross section is very important for operation of both thermal and fast reactors, when loaded with MOX fuels. According to the NEA/OECD High Priority Request List the precision of cross section data for this reaction should be improved. [...]

Pushing the high count rate limits of scintillation detectors for challenging neutron-capture experiments

(Madrid, CIEMAT) ; Cano-Ott, D. (Madrid, CIEMAT) ; González-Romero, E. (Madrid, CIEMAT) et al.
One of the critical aspects for the accurate determination of neutron capture cross sections when combining time-of-flight and total energy detector techniques is the characterization and control of systematic uncertainties associated to the measuring devices. In this work we explore the most conspicuous effects associated to harsh count rate conditions: dead-time and pile-up effects. [...]

Neutron capture and total cross-section measurements on $^{94,95,96}$Mo at n_TOF and GELINA
/ n_TOF Collaboration
Capture and total cross section measurements for 94,95,96Mo have been performed at the neutron time-of-flight facilities, n_TOF at CERN and GELINA at JRC-Geel. The measurements were performed using isotopically enriched samples with an enrichment above 95% for each of the 94,95,96Mo isotopes. [...]

Several cross-section measurements of neutron-induced reactions on Ge found in literature, are performed utilizing natGe targets. The production of the same residual nucleus as the measured one might occur as a result of the unavoidable presence of neighboring isotopes in the same target, acting as a contamination [...]
