Background: Heavy charged particles after nuclear muon capture are an important physics background to the muon-to-electron conversion experiments Mu2e and COMET, which will search for lepton flavor violation at unprecedented level of sensitivity.Purpose: The AlCap experiment aimed measure yield energy spectra protons, deuterons, tritons, $\ensuremath{\alpha}$ emitted muons stopped in Al, Si, Ti low-energy range relevant experiments.Methods: Individual particle types were identified layered...
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....

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...

A feed-forward neural network is demonstrated to efficiently unfold the energy distribution of protons and alpha particles passing through passive material. This model-independent approach works with unbinned data does not require regularization. The training dataset was produced same Monte Carlo simulation framework used by AlCap experiment. common problem designing a also addressed performing hyperparameter space scan find best geometry possible within reasonable computation time. Finally,...

A search for \(\mu \)–e conversion, the COMET experiment, will be conducted at J-PARC. The experiment has two phases. Phase-I aims to measure background directly and conversion with a sensitivity of 10^−15. Phase-II use information gained in utilize much more intense muon beam achieve 10^−17. main detector is cylindrical drift chamber (CDC). CDC installed solenoidal magnetic field, surrounding stopping targets. It was designed efficiently detect signal electrons (105 MeV/c) emitted from...
