DESCRIPTION:Speakers: Victor Alcayne Aicua (CIEMAT (Spain))\nThe neutron t
 ime-of-flight facility n_TOF at CERN is dedicated to measuring neutron-ind
 uced reaction cross-sections of relevance to nuclear technologies\, astrop
 hysics\, and other scientific applications. The facility uses a high-inten
 sity neutron source\, a large lead spallation target coupled with the CERN
 -PS 20 GeV/c proton beam\, and features three experimental areas: Experime
 ntal Area 1 (EAR1)\, located approximately 185 meters horizontally from th
 e spallation target\; Experimental Area 2 (EAR2)\, positioned vertically a
 round 20 meters from the target\; and the newly established NEAR station\,
  located about 3 meters from the target and currently in the commissioning
  phase.\nSince the beginning of the n_TOF collaboration\, CIEMAT has been 
 engaged in capture measurements relevant to nuclear technologies. Over rec
 ent years\, we have been focused on developing new detectors and conductin
 g capture measurements for various isotopes.\nIn the area of detector deve
 lopment\, the sTED detector was constructed and commissioned in 2023 at EA
 R2\, initially with 9 modules. A planned upgrade of the sTED detector to 2
 7 modules is scheduled for construction in 2025\, which will significantly
  enhance the setup’s efficiency. Additionally\, a comprehensive validati
 on of the C$_6$D$_6$ detectors used at n_TOF was completed last year\, dem
 onstrating that the new C$_6$D$_6$-Legnaro detectors exhibit a notably imp
 roved response. Consequently\, further units of these detectors will be ac
 quired to optimize measurement capabilities.\nIn recent years\, several ne
 utron capture cross-section measurements have been conducted in EAR1 using
  C$_6$D$_6$ detectors. These include studies on Tantalum\, relevant for sp
 ace nuclear reactors\; $^{167}$Er\, considered as a burnable absorber for 
 nuclear reactors\; and $^{238}$U\, a major component in light water reacto
 rs. The status of these measurements\, along with the latest details of th
 e data analysis\, will be presented.\n\nhttps://indico.ific.uv.es/event/76
