1. Multi-spectral X-ray imaging with a laser-plasma accelerator
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : This master thesis focuses on the creation of an algorithm to perform multispectral imaging of a metallic target using X-rays. The generation of an ultrashort high-power low-divergent X-ray beam is performed by means of a Ti:Sapphire laser driven wake-field plasma accelerator. READ MORE

2. Relativistic attosecond electron pulses by laser wakefield acceleration
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : The search for cheaper and more compact accelerators has led to the development of laser-driven plasma-based accelerators. In comparison to conventional particle accelerators, the plasma-based accelerator is inherently insensitive to the breakdown of the acceleration structure and therefore greater accelerating fields can be obtained.

3. In-line Phase-contrast Tomography using Betatron X-rays Produced by a Laser-Plasma Accelerator
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : X-ray phase-contrast imaging is a powerful technique that allows great resolving power for low absorbing samples, such as biological tissue. This method relies on measuring the phase shift induced by the sample instead of the absorption traditional radiography relies on. READ MORE

4. Monte Carlo simulations and measurements of the radiation environment at a laser-plasma accelerator
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : 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

5. Interferometric Charecterization of Supersonic Gas-Jets for Laser Wakefield Acceleration
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : The Multi-Terawatt laser at the LLC (Lund Laser Centre) is used to accelerate particles using laser wakefield acceleration. Laser wakefield acceleration is a particle acceleration method that utilizes intense electric fields in plasma created by high intensity laser pulses when passing through gas. READ MORE
