1. 1. Characterization of Mitilysin Pores by Cryo-electron Microscopy

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Vladimir Novakovic; [2023]
   Keywords : Mitilysin; Mly; Structural Biology; Cryo-EM; pore; toxin; pore forming proteins; pore forming toxins; PFP; PFT;

   Abstract : Pore forming toxins (PFTs) are a large group of proteins found mainly in bacteria with some exceptions found in animals. They bind and form pores in their target membranes and form pores, which leads to cell death. Among these are cholesterol-dependent cytolysins (CDC), which require the presence of cholesterol to bind target membranes. READ MORE

3. 2. Feasibility Study of X-ray Free Electron Lasers in Fourth Generation Storage Rings

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/MAX IV-laboratoriet

   Author : Jordis Hansen; [2023]
   Keywords : XFEL; Storage Ring; Synchrotron Radiation; Physics and Astronomy;

   Abstract : This thesis studies the feasibility of a cavity based X-ray free electron laser in a fourth generation storage ring. The cavity design allows for modulation of the electron beam over several passes through the undulator. Simulations based on the PETRA IV facility are done to create the photon flux spectrum of a light pulse produced by an undulator. READ MORE

4. 3. Time-dependent light-matter coupling and quantum dynamics

   University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Author : Daniel Elgbro; [2023]
   Keywords : light-matter interaction; Rabi oscillations; quantum dynamics; optical cavity; qubit; coupled qubit; coupling strength; time-dependent coupling; dynamical qubits; entanglement; concurrence; qubit state manipulation; Jaynes-Cummings; Tavis-Cummings; Physics and Astronomy;

   Abstract : In this thesis, two quantum dynamical system’s of one and two qubits coupled to a field mode confined in an optical cavity have been studied. Within the Jaynes- and Tavis- Cummings model, the dynamics of the corresponding light-matter interaction was defined in terms of the system’s coupling constants. READ MORE

5. 4. RF Compressor (SLED) Phase-Modulation to Reduce Peak Fields in the MAX IV Linear Accelerator

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Joel Ekström; [2023]
   Keywords : Accelerator; MAX IV; LINAC; Phase-modulation; SLED; Pulse compression; Technology and Engineering;

   Abstract : Modern particle accelerators need strong electric fields in order to produce high energy particles. Such high voltages are typically reached by injecting pulsed radio frequency power through several steps of amplification. At the end, pulse compression is used to further improve the energy gain at the cost of pulse-length. READ MORE

6. 5. Application of GEANT4 toolkit for simulations of high gradient phenomena

   University essay from Uppsala universitet/FREIA; Uppsala universitet/Institutionen för teknikvetenskaper

   Author : Daniel Persson; [2018]
   Keywords : GEANT4; XBox 2; XBox; CERN; CLIC; field emission; vacuum breakdown; dark current; breakdown current; spectrometer; FREIA; accelerator; cavity;

   Abstract : To study electron emissions and dark currents in the accelerating structures in particle colliders, a test facility with a spectrometer has been constructed at CERN. This spectrometer has been simulated in the C++ toolkit GEANT4 and in this project the simulation has been improved to handle new realistic input data of the emitted electrons. READ MORE
