Detector characterization and first coincidence tests of a Compton telescope based onLaBr3 crystals and SiPMs

[EN] A Compton telescope for dose monitoring in hadron therapy consisting of several layers of continuous LaBr3 crystals coupled to silicon photomultiplier (SiPM) arrays is under development within the ENVISION project. In order to test the possibility of employing such detectors for the telescope,...
