1. 1. Target and Laser Pulse Optimization for Laser-Driven Ion Acceleration

   Författare :Alexander Permogorov; Atomfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Terawatt laser; Target normal sheath acceleration; laser-driven ion acceleration; proton acceleration; double plasma mirror; Thomson parabola spectrometer; Fysicumarkivet A:2021:Permogorov;

   Sammanfattning : The research presented in this thesis is primarily focused on experimental investigations of laser-driven ion acceleration from solid targets via the target normal sheath acceleration mechanism. In particular, ways of optimizing the absorption of the laser pulse energy by free plasma electrons in the target, or modifying the shape of the accelerating electron sheath were addressed. LÄS MER

3. 2. Laser-driven particle acceleration - Experimental investigations

   Författare :Filip Lindau; Atomfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This thesis describes experimental studies of laser-driven particle acceleration. With the focused intensity of today’s high-power lasers exceeding 10^18 W/cm2,extremely high-gradient accelerators are possible. LÄS MER

4. 3. Laser-driven beams of fast ions, relativistic electrons and coherent x-ray photons

   Författare :Olle Lundh; Atomfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plasma Acceleration of Electrons and Ions; Advanced Accelerator Concepts; X-ray Lasers; Intense Beams and Radiation Sources; Intense Laser-Plasma Interactions;

   Sammanfattning : This thesis presents experimental results on the development and optimization of novel and highly compact sources of beams of fast ions, relativistic electrons and coherent x-rays, driven by intense laser-plasma interactions. The rapid development of high-power, short-pulse laser systems have made available peak powers reaching the petawatt regime and focused intensities reaching 10^21 W/cm2. LÄS MER

5. 4. Approaches to particle acceleration in intense laser-matter interaction

   Författare :Joel Magnusson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; particle-in-cell; nonlinear dynamics; laser; plasma; laser-matter interaction; particle acceleration;

   Sammanfattning : In the interaction of ultra-intense laser fields with matter, the target is rapidly ionized and a plasma is formed. The ability of a plasma to sustain acceleration gradients, orders of magnitude larger than achievable with conventional accelerators, has led to a great interest in laser-driven plasma-based particle acceleration and radiation generation, with applications in materials science, biology and medicine.
