This work aimed to evaluate the dosimetric characteristics of the new HyperScint<jats:sup>TM<\/jats:sup> Research Platform 200 system (HS-RP200), with orthovoltage beams and a novel kilovoltage converging beam, converging radiotherapy and radiosurgery (CRnR) beam. <jats:italic>Approach<\/jats:italic>. Several dosimetric properties of the HS-RP200 detector with several orthovoltage beams were studied in air. Relative dosimetry of the HS-RP200 detector was also studied for use on the converging x-ray beam. Energy correction factors were compared between measurement, Monte Carlo, and analytical methods. <jats:italic>Main results.<\/jats:italic> The signal-to-noise ratio for the detector increased as the frame exposure time increased, and repeated measurements had less uncertainty when measurements were performed without stem-effect removal (WOSER). The short-term stability study of the detector\u2019s signal showed an acceptable variance of its readings to within 1% during 1 h measurements. The detector exhibited angular independence within the measurement uncertainty of 1%. The detector exhibited excellent dose linearity response with the orthovoltage beams. During an 80 d period, repeated measurements determined that the detector possesses long-term stability within a root mean square (rms) of 2.3% and 0.6% when measurements were performed with stem effect removal and WOSER, respectively. Calculated energy correction factors implied significant fluctuations of the HS-RP200 detector with the beam quality of orthovoltage beams, ranging from 3% to 66%, depending on the divergence of the effective energy of the beam from reference quality. Monte Carlo\u2013simulated energy correction factors agreed with measurements with a maximum difference of 5.4% when measurements were performed WOSER. Lastly, the HS-RP200 detector system exhibited good relative dosimetric characteristics with the CRnR beam. A maximum rms value of 0.019 was calculated for the normalized profiles when measurements from the HS-RP200 detector were compared to measurements from film. <jats:italic>Significance<\/jats:italic>. The HS-RP200 detector could be used as an alternative to other detectors with orthovoltage beams, including the CRnR beam.<\/jats:p>","DOI":"10.1088\/1361-6560\/ae0efb","type":"journal-article","created":{"date-parts":[[2025,10,2]],"date-time":"2025-10-02T22:57:11Z","timestamp":1759445831000},"page":"205028","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Characterization of the Medscint HYPERSCINT scintillation dosimetry research platform with orthovoltage photon beams and a novel quasi monoenergetic beam"],"prefix":"10.1088","volume":"70","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9896-207X","authenticated-orcid":true,"given":"Leonard","family":"Che Fru","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8113-0493","authenticated-orcid":true,"given":"Benjamin A","family":"Insley","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9874-5806","authenticated-orcid":true,"given":"Dongyeon","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5792-2207","authenticated-orcid":true,"given":"Dirk A","family":"Bartkoski","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1323-8942","authenticated-orcid":true,"given":"Reza","family":"Reiazi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-4665-1222","authenticated-orcid":true,"given":"Aviad","family":"Schori","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8144-2622","authenticated-orcid":false,"given":"Ramesh","family":"Tailor","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8090-2770","authenticated-orcid":false,"given":"Mohammad","family":"Salehpour","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2025,10,17]]},"reference":[{"key":"pmbae0efbbib1","doi-asserted-by":"publisher","first-page":"2271","DOI":"10.1118\/1.1943807","type":"journal-article","article-title":"Plastic scintillation dosimetry: optimal selection of scintillating fibers and scintillators","volume":"32","author":"Archambault","year":"2005","journal-title":"Med.
