Abstract: Abstract of thesis entitled SIMULATIONS AND SOFTWARE DEVELOPMENTS FOR COSMIC-RAY AND PARTICLE PHYSICS EXPERIMENTS IN UNDERGROUND LABORATORIES submitted by Tsang Hei Man for the Degree of Master of Philosophy at The University of Hong Kong in October 2007 The aim of the Daya Bay Reactor Neutrino Experiment is to measure θ, the last 13 unknown mixing angle that characterizes the neutrino oscillation phenomenon, to a sensitivity level of 0.01 or better in sin θ with a confidence level of 90%. To 13 achieve such an accuracy, background suppression is essential. While the Daya Bay Experiment will be performed underground to shield against low energy cosmic-ray muons, the measurement can also be affected by, for example, spallation neutronsby cosmic-ray muons and natural radioactivity in the surrounding environment. TheAberdeenTunnelExperimentinHongKongaimstomeasurebackgroundra- diationinasimilarundergroundenvironment. Inparticular, thespallationneutrons induced by cosmic-ray muons will be measured using a muon tracker and a neutron detector. In addition to muon-induced background, gamma radiations from natural 238 232 radioactivesources, forexampletheradio-nuclidesinthe U seriesand Thseries 40 and K, can also, potentially, create chance coincidence in the detectors, which is similar to a muon-induced signal expected in the Daya Bay Experiment. Inthisstudy, theperformanceofGEANT4, asimulationtoolforparticlephysics experiments, in gamma simulations was first validated by comparison with experi- mentalmeasurementandothersimulationmethods, includingafiniteelementsimu- lation. Then, someGEANT4simulationstudiesonthenecessityofleadshieldingfor reducing low energy gamma background from rock in the Aberdeen Tunnel Experi- ment was performed. The use of lead shielding in the Aberdeen Tunnel Experiment can be avoided by choosing suitable time windows for the detectors. The effect of background gamma radiation from radio-nuclides in the rock on Resistive Plates Chambers (RPC) in the Daya Bay Experiment was also assessed by means of a GEANT4 simulation of the RPC setup in the Daya Bay Experiment. The results were consistent with previous experimental measurements and suggest that the chance coincidence of RPCs by gamma can be reduced significantly by the use of spacers and requiring multiple coincidence.ThedataacquisitionsoftwaredevelopmentfortheAberdeenTunnelExperiment was described. Finally, a discussion on the offline analysis program for the recon- struction of muon tracks and muon angular distribution written for the Aberdeen Tunnel Experiment was presented.

Download or read book Astroparticle Particle Space Physics and Detectors for Physics Applications written by S. Giani and published by World Scientific. This book was released on 2012 with total page 1100 pages. Available in PDF, EPUB and Kindle. Book excerpt: The exploration of the subnuclear world is done through increasingly complex experiments covering a wide range of energy and performed in a large variety of environments ranging from particle accelerators, underground detectors to satellites and the space laboratory. Among recent advances one has to indicate, for instance, first results obtained from space and LHC experiments and progress done in preparation of the latter experiments upgrades, including plans for the LHC machine upgrade. The achievement of these research programs calls for novel techniques, new materials and instrumentation to be used in detectors, often of large scale. Therefore, fundamental physics is at the forefront of technological advance and also leads to many applications. Among these, medical applications have a particular importance due to health and social benefits they bring to the public. Sample Chapter(s). Science highlights from the Fenni Observatory (5,046 KB). Contents: Space Experiments and Cosmic Rays Observations; Production and Propagation of Cosmic Rays in the Galaxy and Heliosphere; Dark Matter Searches, Underwater and Underground Experiments; High Energy Physics Experiments; Tracker and Position Sensitive Detectors; Calorimetry; Advanced Detectors, Particles Identication, Devices and Materials in Radiation; Broader Impact Activities, Treatments and Software Application.

Available in PDF, EPUB and Kindle. Book excerpt: Over recent years there has been marked growth in interest in the study of techniques of cosmic ray physics by astrophysicists and particle physicists. Cosmic radiation is important for the astrophysicist because in the farther reaches of the universe. For particle physicists, it provides the opportunity to study neutrinos and very high energy particles of galactic origin. More importantly, cosmic rays constitue the background, and in some cases possibly the signal, for the more exotic unconfirmed hypothesized particles such as monopoles and sparticles. Concentrating on the highest energy cosmic rays, this book describes where they originate, acquire energy, and interact, in accreting neutron stars, supernova remnants, in large-scale shock waves. It also describes their interactions in the atmosphere and in the earth, how they are studied in surface and very large underground detectors, and what they tell us.
