“Crystal Collimator” Measurement of CESR particle-beam Source Size
We have measured electron and positron beam source size at CHESS when the Cornell Electron Storage Ring (CESR) is run dedicated for the production of synchrotron radiation. Horizontal source size at several beamlines is expected to shrink by a factor of two but synchrotron (visible) light measurements only provide the vertical size. Therefore a “crystal collimator” using two Bragg reflection in...
متن کاملMeasurement of reflective liquid crystal displays
Cell gap thickness is one of the most important design parameters for liquid crystal displays ~LCD!. Existing measurement methods only apply to transmittive LC cells. These methods are obviously unsuitable for measuring the cell gaps of reflective LCDs with internal reflectors. This kind of LCD includes single polarizer reflective displays and liquid crystal on silicon displays. The objective o...
متن کاملSize Distribution Measurement of Candle\'s Soot Nanoparticles by Using Time Resolved Laser Induced Incandescence
Time resolved laser induced incandescence (LII) technique is used to measure size distribution of soot nanoparticles of candle's flame. Pulsed Nd:YAG laser is used to heat nanoparticles to incandescence temperature and the resulting signal is measured. Mass and energy balance equations are numerically solved to calculate temperature of soot particles in low fluence regime. Assuming Plank black ...
متن کاملIn-situ Measurement of Liquid Crystal Spatial Light Modulators’ Beam Steering Characteristics During Gamma Irradiation
Recent interest in liquid crystal spatial light modulators as a potential replacement to traditional optical beam steering methods have engendered experiments to determine the technology’s resistant to gamma radiation such as may be encountered in a space environment. We previously investigated the effects of exposure of liquid crystal devices to ionizing radiation to total dose levels consiste...
متن کاملPrimary Particle Size Distribution Measurement of Nanomaterials by Using TEM
Industrial applications of nano-particles are reported in many fields recently. Regulation of nano-materials is also discussed in Organization for Economic Co-operation and Development (OECD). European Union (EU) announced the definition of nano-material in 2012. According to EU definition, nanomaterial means a natural, incidental or manufactured material containing particles, in an unbound sta...
