Development of a liquid scintillator-based 3D detector for range measurements of spot-scanned proton beams
The goal of the present study is to develop a liquid scintillator-based 3D detector and investigate its performance for beam range measurements in real time. The detector design consists of a tank filled with water-equivalent liquid scintillator that scintillates in response to incident proton beams. Three scientific complementary metal-oxide semiconductor (sCMOS) cameras collect the resulting ...
متن کاملDeriving detector‐specific correction factors for rectangular small fields using a scintillator detector
The goal of this study was to investigate small field output factors (OFs) for flat-tening filter-free (FFF) beams on a dedicated stereotactic linear accelerator-based system. From this data, the collimator exchange effect was quantified, and detector-specific correction factors were generated. Output factors for 16 jaw-collimated small fields (from 0.5 to 2 cm) were measured using five differe...
متن کاملPerformance characterization of a 3D liquid scintillation detector for discrete spot scanning proton beam systems.
Existing systems for proton beam dosimetry are limited in their ability to provide a complete, accurate, and detailed account of volumetric dose distribution. In this work, we describe the design and development of a portable, fast, and reusable liquid scintillator-based three-dimensional (3D) optical detection system for use in proton therapy. Our long-term goal is to use this system clinicall...
متن کاملProton beam dosimetry: a comparison between a plastic scintillator, ionization chamber and Faraday cup.
In this study, a comparison was made between a plastic scintillator (BC400), a Faraday Cup (FC) and an ionization chamber (IC) used for routine proton dosimetry. Thin scintillators can be applied to proton dosimetry and consequently to proton therapy as relative dosimeters because of their water-equivalent nature, high energy-light conversion efficiency, low dimensions and good proportionality ...
متن کاملResponse of a scintillating fibre detector to proton and pion beams at GSI
The HERMES collaboration at DESY will install a new recoil detector surrounding its target region for the envisaged final two years of the HERA II running period aiming at detecting recoiling nucleons from hard exclusive scattering [1, 2]. Protons and Pions with momenta p > 250 MeV/c will be detected and identified by a two–barrel scintillating fibre tracker (SFT). It consists of two barrels ma...
