  1. 1. Optimization and Characterization of Luminescent Materials for the ESS Proton Beam Imaging System

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Emelie Wiklund; Anton Järild; [2021]
    Keywords : Chemical Engineering; Luminescent materials; Cr-doped Alumina; Proton Beam Imaging System; ESS; Chemistry; Technology and Engineering;

    Abstract : Spallation sources such as European Spallation Source (ESS) produces neutrons by bombarding high-energy protons onto the target wheel. To determine the location of the proton beam a Proton Beam Imaging (PBI) system will be installed. READ MORE

  3. 2. Ray Tracing and Spectral Modelling of Excited Hydroxyl Radiation from Cryogenic Flames in Rocket Combustion Chambers

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Jaka Perovšek; [2018]
    Keywords : spectral modelling; excited hydroxyl radiation; OH* radiation; ray tracing; spectroscopy; rocket combustion chambers; rocket engines; hydrogen-oxygen combustion; combustion instabilities;

    Abstract : A visualisation procedure was developed which predicts excited hydroxyl (OH*) radiation from the Computational Fluid Dynamics (CFD) solutions of cryogenic hydrogen-oxygen rocket flames. The model of backward ray tracing through inhomogeneous media with a continuously changing refractive index was implemented. READ MORE

  4. 3. Measurements and analysis of atomic emission from atomic Li, Na, and K seeded in different flames for potential application to temperature sensing

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Yuhe Zhang; [2017]
    Keywords : Flame Emission Spectroscopy; temperature measurement; alkali metal atoms; Physics and Astronomy;

    Abstract : Alkali metal atoms, especially sodium and potassium, show an intense fluorescence in hot flue gases. The bright fluorescence emitted by alkali metal atoms offers a large potential for spectroscopic combustion analysis. READ MORE

  5. 4. Optical Remote Measurements of Particles in Emission Gas Plumes

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Weihua Wang; [2017]
    Keywords : Absorption spectroscopy; Aerosol; DOAS; SOF; Temporal-spatial data analysis; 吸收光谱学; 气溶胶; 差分吸收光谱技术; 掩光通量测量法; 时空域数据分析;

    Abstract : This project aims to use temporal and spatial data analysis to express the measured air pollutant concentrations as well as their relation with the aerosol traces, indicated by the intensity ratio (IR). The surveying were performed during a field campaign of several days of mobile optical remote sensing measurements in Tianjing city, China. READ MORE

  6. 5. Spectral Analysis of Flame Emission for Optimization of Combustion Devices on Marine Vessels

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik
