  1. 1. Tuning of the ESS Drift Tube Linac using Machine Learning

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB

    Author : Johan Lundquist; [2022]
    Keywords : Accelerator; drift tube linac; machine learning; neural network; ESS; linac; tuning; proton; longitudinal dynamics; beam physics; Physics and Astronomy;

    Abstract : The European Spallation Source, currently under construction in Lund, Sweden, will be the world's brightest neutron source. It is driven by a linear accelerator designed to accelerate a beam of protons with 62.5 mA, 2.86 ms long pulses, working at 14 Hz. READ MORE

  2. 2. Demonstrating quantum entanglement and Hong-Ou-Mandel effect, using type-II spontaneous parametric down conversion with C programming for data collection

    University essay from KTH/Fysik

    Author : Erik Svanberg; Johan Johannisson Lundquist; [2022]
    Keywords : Quantum entanglement; polarization; HOM; Hong-Ou-Mandel; indistinguishability; type-II SPDC; spontaneous parametric down conversion; non-linear crystal; beam splitter; indistinguishable photons; data collection in C;

    Abstract : Spontaneous parametric down conversion (SPDC) is used to generate quantum entangled photons through a non-linear crystal. The entanglement of photons is demonstrated by observing the effects of indistinguishability on photons, first through time and energy, then by polarization. The Hong-Ou-Mandel (HOM) effect was also demonstrated. READ MORE

  3. 3. Frequency Map Analysis of the MAX IV Storage Rings

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

    Author : Johan Lundquist; [2019]
    Keywords : Accelerator; MAX IV; Tune; Diagnostics; Turn by turn; Frequency map; Chromaticity; Beta function; BPM; Synchrotron; Physics and Astronomy;

    Abstract : As a beam of particles moves through a storage ring each particle will perform transverse oscillations as a result of the focusing magnetic fields it encounters. The amount of transverse oscillations performed in a single revolution of the ring is known as the particle's betatron tune. READ MORE
