  1. 1. Development of a DC Beam Model for the First Prototype of the ESS Virtual Machine

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

    Author : Benjamin Bolling; [2019]
    Keywords : Particle; Accelerator; Beam; Physics; Science; Virtual Machine; Virtual; Machine; Physics and Astronomy;

    Abstract : The European Spallation Source is currently under construction in Lund, Sweden. Consisting of a linear accelerator delivering an unprecedented 5 MW proton beam to the spallation source, i.e. READ MORE

  2. 2. Fitting the three loop pion mass and decay constant to lattice data

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik; Lunds universitet/Teoretisk partikelfysik; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Author : Alexandra Wernersson; [2019]
    Keywords : Chiral Perturbation Theory; Lattice QCD; pion mass; decay constant; three loop fit.; Physics and Astronomy;

    Abstract : We perform a fit to three loop order (NNNLO) in Chiral perturbation theory of the pion mass and decay constant. In particular we investigate if the NNNLO fit is an improvement of the fit to two loop order (NNLO) to lattice QCD data, which was done in a lattice gauge group collaboration. READ MORE

  3. 3. Microarray Quality Control using Artificial Neural Networks

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik; Lunds universitet/Beräkningsbiologi och biologisk fysik

    Author : Emil Andersson; [2019]
    Keywords : Artificial Neural Network; ANN; Microarray; Quality Control; Automated Quality Control; Physics and Astronomy;

    Abstract : When using antibody microarrays to diagnose diseases, the process of quality control of the microarray data is an important step. Currently, a part of this process is performed manually by visual inspection. READ MORE

  4. 4. A Fabry–Pérot Cavity for Rare-Earth-Ion-Doped Nanocrystals

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

    Author : Andre Nüsslein; [2019]
    Keywords : Quantum Computer; Rear Earth Ions; Cavity; Laser; Cavity Quantum Electrodynamics; QED; Solidworks; Physics and Astronomy;

    Abstract : This thesis work contributes to the effort of detecting single rare earth ions doped into crystals, an operation crucial for the development of rare earth quantum computer hardware. Doping crystals with rare earth elements, their trivalent ions substitute some of the crystal’s original bonds. READ MORE

  5. 5. Dispersion management and characterization of ultrashort laser pulses for the optimization of parametric processes

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

    Author : Axel Elfving; [2019]
    Keywords : frequency resolved optical gating; optical parametric amplification; difference frequency generation; nonlinear optics; laser pulse compression; lasers; optics; Technology and Engineering; Physics and Astronomy;

    Abstract : This thesis set out to continue the development of a short-wave infrared (SWIR) optical parametric amplifier (OPA). The system is based on a Yb-ber chirped pulse amplification (CPA) laser delivering 400 fs long pulses, centered around 1030 nm, at 200 kHz repetition rate and 40 W average power. READ MORE
