  1. 1. Numerical Study on Acoustic Phenomena in Cavities for Aero-engine Applications

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Eglantin Gjoni; [2023]
    Keywords : ;

    Abstract : For about seventy years, noise generated by grazing flow past a cavity has been thoroughly studied. Yet, a coherent theory that describes such phenomena is missing. Lately, this phenomena started to be investigated in bleeding systems of aero-engines. READ MORE

  3. 2. Problematiken med att prissätta skyddsvärda träd : en kritisk granskning av två monetära värderingsverktyg för träd

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Olivia Bjurström; Emil Seipel; [2023]
    Keywords : urbana träd; biologisk mångfald; särskilt skyddsvärda träd; naturskyddsvärden; monetär värdering; monetärt värde; instrumentellt värde; strukturellt värde; kvantifieringskritik;

    Abstract : I takt med att skyddsvärda träd i städer minskar har flera värderingsverktyg skapats för att skydda dessa genom att ge träd ett ekonomiskt värde. Många av dessa har fått kritik för att inte spegla trädens fulla värde. READ MORE

  4. 3. Developing an ML-based model for RF tuning of the DTL machine at ESS

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Amin Hosseini Nejad; [2023]
    Keywords : Technology and Engineering;

    Abstract : The European Spallation Source (ESS) infrastructure is being constructed in Lund, and will be one of the most powerful research facilities of its type in the world. The ESS linear accelerator (linac) utilizes different accelerating sections where a wide variety of techniques should be employed to accelerate a beam of protons to 2 GeV kinetic energy through Radio Frequency (RF) cavities before being collided with a tungsten target for the final production of neutrons, through the process of spallation.

  5. 4. Cavity Beam Position Monitors State of the Art and Design Studies in the Context of the ILC Project

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola

    Author : Laura Karina Pedraza Motavita; [2023]
    Keywords : Technology and Engineering;

    Abstract : The aim of this master thesis project is the study and evaluation of the design of cavity beam position monitors (BPM) for the International Linear Collider (ILC) project. The state-of-the-art of BPMs is investigated to determine the most appropriate existing BPM design for the requirements of the ILC. READ MORE

  6. 5. Feasibility Study of X-ray Free Electron Lasers in Fourth Generation Storage Rings

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/MAX IV-laboratoriet

    Author : Jordis Hansen; [2023]
    Keywords : XFEL; Storage Ring; Synchrotron Radiation; Physics and Astronomy;

    Abstract : This thesis studies the feasibility of a cavity based X-ray free electron laser in a fourth generation storage ring. The cavity design allows for modulation of the electron beam over several passes through the undulator. Simulations based on the PETRA IV facility are done to create the photon flux spectrum of a light pulse produced by an undulator. READ MORE
