1. 1. A Near-Infrared Diffraction Radiation Spectrometer for MHz Repetition Rate Electron Bunch Diagnostics at the European XFEL

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Simon Fahlström; [2019]
   Keywords : European XFEL; XFEL; Free-Electron Laser; FEL; bunch diagnostics; Coherent Diffraction Radiation; Spectrometer;

   Abstract : We have built a spectrometer to investigate the Near-Infrared (NIR) range of this radiation, which is used for bunch diagnostics at the European X-ray Free-Electron Laser. This could give information on the development of microbunching, periodic features in the longitudinal charge profile of the bunches which have a negative impact on the operation of the facility.

3. 2. Modelling of injection of electrons by low-dimensional nanowire into a reservoir

   University essay from Linköpings universitet/Teoretisk Fysik

   Author : Ivan Yakymenko; [2018]
   Keywords : quantum wire; magnetic electron focusing; electron flow; electron injector and detector; semiconductor heterostructure; two-dimensional electron gas;

   Abstract : High-mobility two-dimensional electron gas (2DEG) which resides at the interface between GaAs and AlGaAs layered semiconductors has been used experimentally and theoretically to study ballistic electron transport. The present project is motivated by recent experiments in magnetic electron focusing. READ MORE
