ProtoDUNE Single-Phase (ProtoDUNE-SP) is a 770-ton liquid argon time projection chamber that operated in a hadron test beam at the CERN Neutrino Platform in 2018. We present a measurement of the total inelastic cross section of charged kaons on argon as a function of kaon energy using 6 and 7 GeV=c beam momentum settings. The flux-weighted average of the extracted inelastic cross section at each beam momentum setting was measured to be 380 26 mbarns for the 6 GeV=c setting and 379 35 mbarns for the 7 GeV=c setting. 2025-03-03T12:01:32Z 2025-03-03T12:01:32Z 2024-11-14 journal article A.
