  1. 21. Monte Carlo simulations and measurements of the radiation environment at a laser-plasma accelerator

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

    Author : Jack Strand Berg; [2016]
    Keywords : Physics and Astronomy;

    Abstract : In current experiments at the high-power laser facility at the Lund Laser Centre, electrons accelerated to hundreds of MeV over short distances by means of laser wakefield acceleration in produced plasmas. To determine the amount of secondary radiation generated when accelerated electrons interact with surrounding materials is of interest to ensure a safe working environment. READ MORE

  3. 22. Reproducibility of bunches of electrons accelerated in laser driven wakefields

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

    Author : Philip Siederer; [2016]
    Keywords : Laser; wakefield; acceleration; electron acceleration; plasma; LWFA; Physics and Astronomy;

    Abstract : Laser wakefield acceleration (LWFA) utilises a high intensity laser pulse to excite a plasma density wave with associated large directed electric fields. These large electric fields can be used to accelerate electrons, making LWFA a good candidate for a compact electron beam source. READ MORE

  4. 23. Tests and simulations of GEM foils for use in an active target gaseous detector

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

    Author : Jacob Snäll; [2016]
    Keywords : GEM; ISOLDE; gas electron multiplier; Garfield ; Physics and Astronomy;

    Abstract : The HIE-ISOLDE post accelerator at CERN has recently come online, en- abling the use of radioactive ion beams with energies of up to 10 MeV/u. An active target gaseous detector is under development for use in some of the experiments. The first investigation of the electron amplification stage with gas electron multipliers has been performed. READ MORE

  5. 24. Parametric study of density down-ramp injection in laser wakefield acceleration

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

    Author : Henrik Ekerfelt; [2015]
    Keywords : Laser wakefield acceleration; LWFA; gradient injection; density down-ramp injection; particle-in-cell simulation; PIC; top-view; top view; Thomson scattered light; trace; Physics and Astronomy;

    Abstract : In laser wakefield acceleration (LWFA) a high intensity laser pulse is used to excite a plasma density wave with an associated electric field. This electric field can be used to accelerate electrons. However, to be accelerated the electrons first of all need to enter the plasma wave. This process is called injection. READ MORE

  6. 25. Is it possible to detect the η' → e+e- decay? : A simulation of the η' decay from e+e- collisions

    University essay from Uppsala universitet/Kärnfysik

    Author : Daniel Hamnevik; [2014]
    Keywords : simulation; etaprime; eta prime; lepton decay; e e- collisions;

    Abstract : Decays of light, pseudoscalar mesons into lepton pairs are one possible way of detecting physics beyond the Standard Model. This thesis will focus on the η' → e+e- decay, because only few experiments have studied this decay. READ MORE
