Fluorescence of tetraphenyl-butadiene in the vacuum ultraviolet.
Tetraphenyl-butadiene is a useful alternative to sodium salicylate as a fluorescent wavelength converter for detectors in the vacuum uv. Measurements of the fluorescence efficiency of TPB relative to sodium salicylate over the wavelength range 735-3160 A are presented, and the application of TPB coatings to image tube detectors is discussed. Over the entire wavelength range studied TPB had a hi...

15 صفحه اولLinear stability of particle-laden thin films
Recent experiments [Zhou, Dupuy, Bertozzi, and Hosoi, Phys. Rev. Lett., 94 (2005)] of particle-laden film flow on an incline demonstrate new behavior distinct from the well-known clear fluid case, including the formation of a particle-rich ridge which can stabilize the advancing contact line with respect to “fingering” perturbations. We consider a model similar to that of Zhou et al. with the a...
متن کاملFabrication of an alpha particle counter: spin coated films of synthesized nanocrystalline cadmium tungstate powder
Background: CdWO4 is a scintillator with some unique properties. For example, high density, thermal and chemical stability and so on. Different applications of this scintillator such as X-ray scintillator has been investigated thoroughly so far. However, there is limited number of studies reporting the characteristics of CdWO4 as an alpha counter. Materials and Methods: The CdWO4 powder was syn...
متن کاملSome Factors Affecting Alpha Particle Detection In Liquid Scintillation Spectrometry
Pulse shape analyzers have been introduced in commercial liquid scintillation counters, such as the WaIlac 1220 QuantulusTM and 1219 SM, enabling separation of alpha particle spectra from other types of radiation in a single measurement and making ultra sensitive alpha counting possible. Background count rates as low as one count per day for 214Po in a teflon vial are achievable while still ret...
