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. Detector Development, Source Characterization and Novel Applications of Laser Ion Acceleration

   Författare :Lovisa Senje; Atomfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Laser; Ion; Acceleration; Proton; Water; Sheath; Lifetime; Laser; Ion; Acceleration; Proton; Water; Radiolysis; Sheath; Detector; Fysicumarkivet A:2017:Senje;

   Sammanfattning : The main focus of the work presented in this thesis is on experimental studies oflaser acceleration of protons and other positive ions from solid targets. The topic is explored from three different angles: firstly, the development of diagnostics adapted to the ion pulses, secondly, the characterization of the source of the energetic particles and, finally, the application of laser-accelerated protons for time-resolved radiolysis of glass and water.
