1. 1. Computational investigation of the feasibility touse solid neon moderation for GBAR

   University essay from Stockholms universitet/Fysikum

   Author : Lars Gehrmann; [2023]
   Keywords : ;

   Abstract : The main goal of the GBAR (Graviational Behaviour of Antihydrogen at Rest) experiment is to investigatethe gravitational effect on antimatter by measuring the classical free fall of an antihydrogen atom. The requiredpositrons are created by pair production inside a tungsten target and are moderated using a tungsten mesh. READ MORE

3. 2. Multi-ion radiotherapy treatment planning

   University essay from Uppsala universitet/Högenergifysik

   Author : Gustav Lidberg; [2023]
   Keywords : multi-ion radiotherapy; heavy-ion radiotherapy; carbon-ion radiotherapy; treatment planning; LET optimization;

   Abstract : Multi-ion radiotherapy has been suggested as a new way to treat cancer, combining the radiological advantages of lighter and heavier ions in a single treatment to improve plan robustness and increase LETd in the target. To succeed, multi-ion radiotherapy requires a treatment planning system capable of computing dose for and optimising multi-ion treatment plans. READ MORE

4. 3. Ion Induced Particle Desorption From Self Supporting Nanomembranes : Influence of Different Geometries and Particle Types

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Jonas Beling; [2023]
   Keywords : ion; physics; ion physic; scattering; desorption; sputtering; jon; fysik; jonfysik;

   Abstract : Nanoelectronics is a field undergoing rapid development, meaning knowledge of the materials and methods used in nano-scale systems is a driving force in the industry. Silicon is a well known material in nanoelectronics commonly used as a semiconductor and is therefore a good representative for nanomaterials in general. READ MORE

5. 4. Generation and Characterization of Intense Attosecond Pulses

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

   Author : Marius Plach; [2020]
   Keywords : 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;

   Abstract : 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. READ MORE

6. 5. Helical Waveguides With Higher Symmetries

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Mikko Kjellberg; Johan Lundgren; [2018]
   Keywords : ;

   Abstract : Helical waveguides are widely used today as slow wave structures and as normal or axial mode antennas. By introducing higher symmetries in the structure the dispersive properties of the waveguide can be manipulated and the helices can be made to radiate energy as leaky wave antennas. READ MORE
