Investigating the Influence of Filter Uniformity Coefficient and Effective Pore Size on Critical Hydraulic Gradient and Maximum Erosion of Dispersive and Non-dispersive Samples
Filter is one of the main components of embankment dams. By a simple but effective performance, filter protects the dam against erosion and soil scouring in impervious core caused by leakage (piping) and makes it safe. Interaction between filter and erodible base soil is a complex phenomenon which is dependent upon several factors, and has challenged researchers for better understanding the fil...
متن کامل30TH INTERNATIONAL COSMIC RAY CONFERENCE Calibration and monitoring of the air fluorescence detector for the Telescope Array experiment
The air fluorescence detectors (FDs) of the Telescope Array (TA) experiment have been constructed in a dessert of Utah, USA. We can measure the longitudinal developments of EASs directly with the FDs by detecting air fluorescence lights and determine the primary energies of ultra-high energy cosmic rays. In order for accurate observation and measurements of EASs, elaborate detector calibrations...
متن کاملDevelopment of a new photomultiplier tube with high sensitivity for a wavelength-shifter fiber readout
We have developed a new photomultiplier tube (PMT) with high sensitivity for a wavelength-shifter fiber readout of plastic scintillators. Improvements of the photoelectron yield were made on a 2-in. PMT (Hamamatsu R329) by adopting (1) a prism-shaped photocathode, (2) an extended-green photocathode material, and (3) an optical mirror surface of the electrodes. As a result, the number of photoel...
متن کاملDark Matter Detection Characterization of Photomultiplier Tubes for Dark Matter Experiments
Dark matter has become a major topic of research as the attempt to described the gravitatioinal interactions between some unknown substance and the stars that make up the galaxacy has been approached. Photomultiplier tubes are used in the observation of Weakly Interacting Massive Particles (WIMPs) in dark matter detection experiments, such as the Xenon 10 and Xenon 100 experiments conducted at ...
متن کاملConstruction and calibration of detectors for high-resolution metabolic breast cancer imaging
Each of two detectors used in our Positron Emission Mammography (PEM) system consists of four 36 mm x 36 mm x 20 mm bismuth germanate (BGO) crystal detector blocks coupled to a crossed-wire anode position-sensitive photomultiplier tube (PS-PMT). To facilitate high spatial-resolution imaging, the crystal blocks have been finely pixelated using a diamond saw. In each detector, 36 x 36 1.9 mm x 1....
