Feasibility of acoustic neutrino detection with the South Pole Acoustic Test Setup
… large neutrino telescopes is dictated by the attenuation length of the observable signal that is generated by the neutrino interaction with the medium. The optically transparent ice at the geographic South Pole has optical attenuation lengths in the order of 100m. This has allowed the …

Feasibility Analysis and Prototype Measurements of a Novel Approach for the Real-Time Spectroscopy of Low Energy Solar Neutrinos
… of prototype cells were measured, including attenuation length, energy and spatial resolution. First background results of the final LENS prototype are presented. The implications of these investigations for the feasibility of both proposed approaches is discussed.

Numerical Study of Acoustophoretic and Thermophoretic Aggregation of Micro- and Nano-Sized Particles
… height, when normalised by the acoustic wavelength, is found to be between 0.57-0.82. Second, a numerical model is established to investigate the laser heating parameters on thermophoretic enrichment of nanoparticles. In the thermophoresis enrichment system, a microchamber containing …

Synthesis and characterization of cerium-doped lanthanum halide colloidal nanocrystals
… time, and a density of 5.3 g/cm3 with 22 mm attenuation length for 511 keV gamma rays. However, the crystals are hygroscopic and hence have to be protected from external environment both during growth and use. Deriving the motivation from this material, this work strives at successful …

Performance characterization of functional fiber detectors: scintillating fibers with embedded photodiodes
… (SiPMs) have been produced for study. The light attenuation length for each prototype of the functional fiber detectors is measured. In addition, the SiPMs used in this work have been carefully calibrated to obtain the correspondence between the measured energy and the number of photoelectrons …

Attenuation of the scintillation light in liquid argon and investigation of the double beta decay of ⁷⁶Ge into excited states of ⁷⁶Se in the GERDA experiment
… the key parameters of the LAr efficiency is the attenuation of the scintillation light in LAr, which is dependent on the impurity composition and concentration in LAr. Therefore, the attenuation length of the scintillation light in LAr has been measured in GERDA with a dedicated setup in the …

The Daya Bay Reactor Neutrino Experiment
… presented in the thesis covered the water attenuation, spent fuel neutrino and electron anti-neutrino spectrum. Other physics analysis and impact to future experiments are also discussed.
