   Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Författare :Marius Plach; [2020]
   Nyckelord :Attosecond physics; high-order harmonic generation; high harmonic generation; HHG; attosecond pulses; molecular dynamics; attosecond pulse generation; harmonic emission time delay; temporal reconstruction of attosecond pulses; strong field processes; Three-step model; RABBIT; Reconstruction of Attosecond Beating By Interference of Two-photon Transition; Terawatt Laser System; Intense XUV Beamline; XUV; LLC; Physics and Astronomy;

   Sammanfattning : Research on ultrafast dynamics in atoms and molecules requires short pulses. In order to resolve processes taking place on a femtosecond timescale sufficiently, these pulses require a duration on the attosecond time scale. LÄS MER

3. 2. Exploring the Use of Graphene as a Target Material for Laser Plasma Ion Acceleration

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

   Författare :Hannes Pahl; [2017]
   Nyckelord :Laser Plasma Acceleration; Target Material; Graphene; Physics and Astronomy;

   Sammanfattning : The interaction of a solid target with an ultra-high intensity laser pulse can result in the laser plasma acceleration of ions. The recent proposal of a new laser plasma ion acceleration scheme, named chirped standing wave acceleration, has created interest in a new class of ultra-thin solid target materials, either freestanding or as a part of novel compound targets.

4. 3. Interferometric Charecterization of Supersonic Gas-Jets for Laser Wakefield Acceleration

   Kandidat-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Författare :Jonatan Henriksson; [2016]
   Nyckelord :Interferometry; Laser Wakefield Acceleration; Mach-Zehnder; Gas-Jet characterization; Physics and Astronomy;

   Sammanfattning : 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. LÄS MER

5. 4. Reproducibility of bunches of electrons accelerated in laser driven wakefields

   Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

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

   Sammanfattning : 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. LÄS MER
