  1. 1. Sustainable Swedish Industry by Improved Excess Heat Recovery

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Erik Rosengren; [2022]
    Keywords : Excess Heat Recovery; Black Liquor Evaporation; Pulp and Paper; Retrofit; Agenda 2030; Water Technology; Resource Management; Waste Heat; Technical Validation; Chemical Engineering; Water Savings; Energy Efficiency; Greenhouse Gas mitigation; Spillvärme; Indunstning; Svartlut; Pappersmassaindustri; Energieffektivisering; Technology and Engineering;

    Abstract : Achieving a sustainable Swedish industry will require better utilization of resources already available and already spent. Nationally, vast amounts of heat are released into the atmosphere and not made use of. READ MORE

  3. 2. Qualification of WestinghouseBWR lattice physics methods againstcritical experiments

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Kim Landelius; [2016]
    Keywords : HELIOS; PHOENIX5; lattice code;

    Abstract : This thesis is part of a larger qualification effortperformed at Westinghouse Electric Sweden AB of the PHOENIX5 latticephysics code. The aim of the thesis is to validate PHOENIX5 withregards to cold criticality tests performed at the Toshiba NCAfacility in 2010-2011. READ MORE

  4. 3. Element-Specific Magnetization Dynamics Using T-MOKE at the HELIOS Laboratory

    University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Author : Fredrik Stångberg Valgeborg; [2016]
    Keywords : magnetization dynamics; magnetization; demagnetization; magnetism; element-specific; element-specificity; T-MOKE; MOKE; pump-prob; time-resolved pump-probe; HHG; high-order harmonic generation; overtone generation; HELIOS; magnetiseringsdynamik; magnetisering; avmagnetisering; magnetism; grundämnesspecifik; grundämnesspecificitet; T-MOKE; MOKE; pump-prob; tidsupplöst pump-prob; HHG; övertonsgenerering; HELIOS;

    Abstract : Magnetism is a familiar phenomenon, and is applied in a variety of devices, from simple ones, like compasses, to the more sophisticated magnetic hard disk drives. It is also known that the magnetization of a material can change, for example by heating or by exposure to an external magnetic field. READ MORE

  5. 4. Validation and Benchmarking of Westinghouse BWR lattice physics methods

    University essay from KTH/Reaktorteknologi

    Author : Karol Luszczek; [2015]
    Keywords : Serpent; HELIOS; lattice physics; benchmarking; Monte Carlo; neutronics; reactor physics;

    Abstract : A lattice physics code is a vital tool, forming a base of reactor coreanalysis. It enables the neutronic properties of the fuel assembly to becalculated and generates a proper set of data to be used by a 3-D full coresimulator. READ MORE

  6. 5. A Numerical Study of the Wavelength Dependence in an Off-Plane XUV Monochromator : Bachelor of Science Degree Thesis

    University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Author : Jonatan Fast; [2015]
    Keywords : off-plane; off-axis; xuv.; monochromator; femtosecond; pulse; wavelength dependence; chirp; grating; blazed; specular; reflection; diffraction; grazing; high harmonic generation; hhg; helios; ray tracing; ray trace; numerical; pulse length; temporal resolution; beamfour;

    Abstract : In this thesis the work is based around the HELIOS (High Energy Laser Induced Overtone Source) laboratory, a facility at the Division of Molecular and Condensed Matter Physics at the Department of Physics and Astronomy, Uppsala University, Sweden. HELIOS generates XUV (extreme ultraviolet) photon pulses with energies between 15-70 eV and pulse lengths shorter than 50 fs. READ MORE
