The CHIPS experiment will comprise a 10 kton water Cherenkov detector in an open mine pit in northern Minnesota, USA. The detector has been simulated using a full GEANT4 simulation and a series of event reconstruction algorithms have been developed to exploit the charge and time information from all of the PMTs. A comparison of simulated CCQE nu_mu and nu_e interactions using 10 inch and 3 inch PMTs is presented, alongside a comparison of 10% and 6% photocathode coverage for 3 inch PMTs. The studies demonstrate that the required selection efficiency and purity of charged-current nu_e interactions can be achieved using a photocathode coverage of 6% with 3 inch PMTs. Finally, a dedicated pi-zero fitter is shown to successfully reconstruct a clean sample of pi-zero mesons despite the low 6% photocathode coverage with 3 inch PMTs.
The measurement of diffractively scattered protons in the ATLAS Forward Physics detector system placed 220 m away from the ATLAS interaction point is studied. A parameterisation of the scattered proton transport through the LHC magnet lattice is pres
The XENON1T experiment at the Laboratori Nazionali del Gran Sasso is the most sensitive direct detection experiment for dark matter in the form of weakly interacting particles (WIMPs) with masses above $6,$GeV/$c^2$ scattering off nuclei. The detecto
Large-volume liquid scintillator detectors with ultra-low background levels have been widely used to study neutrino physics and search for dark matter. Event vertex and event time are not only useful for event selection but also essential for the rec
We present the performance of a semantic segmentation network, SparseSSNet, that provides pixel-level classification of MicroBooNE data. The MicroBooNE experiment employs a liquid argon time projection chamber for the study of neutrino properties and
For a large liquid argon time projection chamber (LArTPC) operating on or near the Earths surface to detect neutrino interactions, the rejection of cosmogenic background is a critical and challenging task because of the large cosmic ray flux and the
