The experiment uses photoionization with tunable synchrotron radiation and double imaging photoelectron photoion coincidence (i2PEPICO) detection at the vacuum ultraviolet beamline. The experimental setup is described, including the high-pressure reactor experiment, sampling interface, and reactant delivery system. The CRF-PEPICO (Combustion Reactions Followed by Photoelectron Photoion Coincidence) endstation and VUV beamline are briefly elaborated. The novel aspects of the apparatus and the new components are elucidated in detail, such as the fluid supply system to the reactor and the reactor integration into the endstation. We also present a system overview of the experimental setup. The technical details are followed by a description of the experimental procedure used to operate the pressurized flow reactor setup. Finally, first experimental results demonstrating the capability of the setup are provided and analyzed. A major advantage of this new experiment is that the excellent isomer resolution capabilities of the i2PEPICO technique can be transferred to the investigation of reactions at elevated pressures of several bars. This enables the investigation of pressure effects on the reactivity of fuel mixtures and covers more realistic conditions found in technical combustors. The capability to obtain quantitative oxidation data is confirmed, and the main and certain intermediate species are quantified for a selected condition. The results show excellent agreement with a chemical kinetics model and previously published reference measurements performed with a gas chromatography setup.<\/jats:p>","DOI":"10.1063\/1.5141168","type":"journal-article","created":{"date-parts":[[2020,4,21]],"date-time":"2020-04-21T13:12:07Z","timestamp":1587474727000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":10,"title":["A pressurized flow reactor combustion experiment interfaced with synchrotron double imaging photoelectron photoion coincidence spectroscopy"],"prefix":"10.1063","volume":"91","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7227-691X","authenticated-orcid":false,"given":"M.","family":"Hoener","sequence":"first","affiliation":[{"name":"Mass Spectrometry in Reactive Flows \u2013 Institute for Combustion and Gas Dynamics (IVG), University Duisburg-Essen 1 , Duisburg 47057, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6862-6155","authenticated-orcid":false,"given":"D.","family":"Kaczmarek","sequence":"additional","affiliation":[{"name":"Mass Spectrometry in Reactive Flows \u2013 Institute for Combustion and Gas Dynamics (IVG), University Duisburg-Essen 1 , Duisburg 47057, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5764-1015","authenticated-orcid":false,"given":"T.","family":"Bierkandt","sequence":"additional","affiliation":[{"name":"German Aerospace Center (DLR) \u2013 Institute of Combustion Technology 2 , Stuttgart 70569, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2742-1051","authenticated-orcid":false,"given":"A.","family":"Bodi","sequence":"additional","affiliation":[{"name":"Laboratory for Synchrotron Radiation and Femtochemistry \u2013 Paul Scherrer Institute 3 , Villigen 5232, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1251-4549","authenticated-orcid":false,"given":"P.","family":"Hemberger","sequence":"additional","affiliation":[{"name":"Laboratory for Synchrotron Radiation and Femtochemistry \u2013 Paul Scherrer Institute 3 , Villigen 5232, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3993-5316","authenticated-orcid":false,"given":"T.","family":"Kasper","sequence":"additional","affiliation":[{"name":"Mass Spectrometry in Reactive Flows \u2013 Institute for Combustion and Gas Dynamics (IVG), University Duisburg-Essen 1 , Duisburg 47057, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"317","published-online":{"date-parts":[[2020,4,21]]},"reference":[{"key":"2023080707305725300_c1","volume-title":"Ansys Chemkin 19.2","author":"Ansys Inc.","year":"2008"},{"key":"2023080707305725300_c2","doi-asserted-by":"publisher","first-page":"9698","DOI":"10.1039\/c7cp00144d","article-title":"Advances in threshold photoelectron spectroscopy (TPES) and threshold photoelectron photoion coincidence (TPEPICO)","volume":"19","year":"2017","journal-title":"Phys.
