A Segmented Total Energy Detector (sTED) Optimized for (n, *g) Cross-Section Measurements at n_TOF EAR2 / V.Alcayne, V.Furman, [et al.] // Radiation Physics and Chemistry [Electronic resource]. – 2024. – Vol. 217. – P. 111525. – URL: https://doi.org/10.1016/j.radphyschem.2024.111525. – Bibliogr.: p. 111525-(10-11).
The neutron time-of-flight facility n_TOF at CERN is a spallation source dedicated to measurements of neutron- induced reaction cross-sections of interest in nuclear technologies, astrophysics, and other applications. Since 2014, Experimental ARea 2 (EAR2) is operational and delivers a neutron fluence of ∼ 4 ⋅ 10*7 neutrons per nominal proton pulse, which is ∼50 times higher than the one of Experimental ARea 1 (EAR1) of ∼ 8 ⋅ 10*5 neutrons per pulse. The high neutron flux at EAR2 results in high counting rates in the detectors that challenged the previously existing capture detection systems. For this reason, a Segmented Total Energy Detector (sTED) has been developed to overcome the limitations in the detector’s response, by reducing the active volume per module and by using a photo-multiplier (PMT) optimized for high counting rates. This paper presents the main characteristics of the sTED, including energy and time resolution, response to *g-rays, and provides as well details of the use of the Pulse Height Weighting Technique (PHWT) with this detector. The sTED has been validated to perform neutron-capture cross-section measurements in EAR2 in the neutron energy range from thermal up to at least 400 keV. The detector has already been successfully used in several measurements at n_TOF EAR2
