In this work, we investigated the performance of the W2 scintillator in a 10 MV flattening-filter-free photon beam and compared it to the performance of ion chambers designed for small field measurements. (2) Methods: We measured beam profiles and percent depth dose curves with each detector and investigated the linearity of each system based on dose per pulse (DPP) and pulse repetition frequency. (3) Results: We found excellent agreement between the W2 scintillator and the ion chambers for beam profiles and percent depth dose curves. Our results also showed that the two-voltage method of calculating the ion recombination correction factor was sufficient to correct for the ion recombination effect of ion chambers, even at the highest DPP. (4) Conclusions: These findings show that the W2 scintillator shows excellent agreement with ion chambers in high DPP conditions.<\/jats:p>","DOI":"10.3390\/s22186785","type":"journal-article","created":{"date-parts":[[2022,9,8]],"date-time":"2022-09-08T07:05:56Z","timestamp":1662620756000},"page":"6785","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Characterization of the Plastic Scintillator Detector System Exradin W2 in a High Dose Rate Flattening-Filter-Free Photon Beam"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9915-7443","authenticated-orcid":false,"given":"Sara","family":"Thrower","sequence":"first","affiliation":[{"name":"Department of Radiation Physics, The University of Texas MD Anderson Cancer Center, Houston, TX 77030, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3531-8054","authenticated-orcid":false,"given":"Surendra","family":"Prajapati","sequence":"additional","affiliation":[{"name":"Department of Radiation Physics, The University of Texas MD Anderson Cancer Center, Houston, TX 77030, USA"},{"name":"Medical Physics Program, The University of Texas MD Anderson UTHealth Graduate School of Biomedical Sciences, Houston, TX 77030, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shannon","family":"Holmes","sequence":"additional","affiliation":[{"name":"Standard Imaging Inc., Middleton, WI 53562, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emil","family":"Sch\u00fcler","sequence":"additional","affiliation":[{"name":"Department of Radiation Physics, The University of Texas MD Anderson Cancer Center, Houston, TX 77030, USA"},{"name":"Medical Physics Program, The University of Texas MD Anderson UTHealth Graduate School of Biomedical Sciences, Houston, TX 77030, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5825-110X","authenticated-orcid":false,"given":"Sam","family":"Beddar","sequence":"additional","affiliation":[{"name":"Department of Radiation Physics, The University of Texas MD Anderson Cancer Center, Houston, TX 77030, USA"},{"name":"Medical Physics Program, The University of Texas MD Anderson UTHealth Graduate School of Biomedical Sciences, Houston, TX 77030, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"12","DOI":"10.1120\/jacmp.v16i3.5219","article-title":"Flattening filter-free accelerators: A report from the AAPM Therapy Emerging Technology Assessment Work Group","volume":"16","author":"Xiao","year":"2015","journal-title":"J.
