Abstract Properties of different scintillating fibers were examined and compared, as a part the design optimization SiFi-CC detector, currently under development for proton therapy monitoring. Three materials considered candidates to constitute active detector: LYSO:Ce, LuAG:Ce GAGG:Ce. All investigated samples had an elongated, fiber-like shape read out on both ends using silicon photomultipliers (SiPMs). Samples LYSO:Ce material provided by four manufacturers included in survey....

Abstract Recent years have shown an increased use of silicon photomultipliers (SiPM) in experiments as they are reasonable cost, relatively low power consumption and easily available a variety form factors allowing for large number readout channels. At the same time, generating data at increasingly high rates requiring more efficient systems. In this work, dead efficiency, dynamic range, coincidence time resolution energy five different systems various stages maturity evaluated to determine...
Objective: Proton therapy is a precision-focused cancer treatment where accurate proton beam range monitoring critical to ensure effective dose delivery. This can be achieved by prompt gamma detection with Compton camera like the SiFi-CC. study aims show feasibility of optimising geometry SiFi-CC for verification distribution via using genetic algorithm (GA). Approach: The key geometric parameters optimisation GA are source-to-scatterer and scatterer-to-absorber distances, module...
