Comparison of penh, fluka, and Geant4/topas for absorbed dose calculations in air cavities representing ionization chambers in high-energy photon and proton beams KU Leuven
PURPOSE: The purpose of this work is to analyze whether the Monte Carlo codes penh, fluka, and geant4/topas are suitable to calculate absorbed doses and f Q / f Q 0 ratios in therapeutic high-energy photon and proton beams. METHODS: We used penh, fluka, geant4/topas, and egsnrc to calculate the absorbed dose to water in a reference water cavity and the absorbed dose to air in two air cavities representative of a plane-parallel and a ...
Deep proton writing with 12 MeV protons for rapid prototyping of microstructures in polymethylmethacrylate Universiteit Gent Vrije Universiteit Brussel
Deep proton writing ( DPW) is a fabrication technology developed for the rapid prototyping of polymer microstructures. We use polymethylmethacrylate (PMMA) substrates, which act as a positive resist, for irradiation with a collimated 12-MeV energy proton beam. Using 12 MeV enables the irradiation of increasingly thick PMMA substrates with less conicity of the sidewalls compared to the lower energies used in previous work. A microhole of 47.7 mu ...
Search for the production of four top quarks in the single -lepton and opposite -sign dilepton final states in proton -proton collisions at √s==13 TeV Universiteit Antwerpen Universiteit Gent Vrije Universiteit Brussel
A search for the standard model production of four top quarks (pp tttt) is reported using single-lepton plus jets and opposite-sign dilepton plus jets signatures. Proton-proton collisions are recorded with the CMS detector at the LHC at a center-ofmass energy of 13 TeV in a sample corresponding to an integrated luminosity of 35.8 fb-1. A multivariate analysis exploiting global event and jet properties is used to discriminate tttt from tt ...
Measurements of the differential jet cross section as a function of the jet mass in dijet events from proton -proton collisions at=13 TeV Universiteit Gent Vrije Universiteit Brussel Universiteit Antwerpen
Measurements of the differential jet cross section are presented as a function of the jet mass in dijet events, in bins of jet transverse momentum, with and without a jet grooming algorithm. The data have been recorded by the CMS Collaboration in proton-proton collisions at the LHC at a center-of-mass energy of 13 TeV and correspond to an integrated luminosity of 2.3 fb(-1). The absolute cross sections show slightly different jet transverse ...
Combined measurements of Higgs boson couplings in proton- proton collisions at v s=13TeV Universiteit Gent Universiteit Antwerpen
Combined measurements of the production and decay rates of the Higgs boson, as well as its couplings to vector bosons and fermions, are presented. The analysis uses the LHC proton-proton collision data set recorded with the CMS detector in 2016 at fb-1. The combination is based on analyses targeting the five main Higgs boson production mechanisms (gluon fusion, vector boson fusion, and associated production with a W or Z boson, or a top ...
Treatment planning comparison in the PROTECT-trial randomising proton versus photon beam therapy in oesophageal cancer: Results from eight European centres KU Leuven
PURPOSE: To compare dose distributions and robustness in treatment plans from eight European centres in preparation for the European randomized phase-III PROTECT-trial investigating the effect of proton therapy (PT) versus photon therapy (XT) for oesophageal cancer. MATERIALS AND METHODS: All centres optimized one PT and one XT nominal plan using delineated 4DCT scans for four patients receiving 50.4 Gy (RBE) in 28 fractions. Target volume ...
Evaluation of Gafchromic® EBT3 films characteristics in therapy photon, electron and proton beams KU Leuven
To evaluate the uncertainties and characteristics of radiochromic film-based dosimetry system using the EBT3 model Gafchromic(®) film in therapy photon, electron and proton beams.
The European Particle Therapy Network (EPTN) consensus on the follow-up of adult patients with brain and skull base tumours treated with photon or proton irradiation KU Leuven
PURPOSE: Treatment-related toxicity after irradiation of brain tumours has been underreported in the literature. Furthermore, there is considerable heterogeneity on how and when toxicity is evaluated. The aim of this European Particle Network (EPTN) collaborative project is to develop recommendations for uniform follow-up and toxicity scoring of adult brain tumour patients treated with radiotherapy. METHODS: A Delphi method-based consensus was ...
