1. Ultrafast resonant magnetic scattering at the European XFEL
Sammanfattning : Magnetic materials are of interest in a wide range of nanotechnologies such as for data storage, memory, logic, and sensing applications. Today, there is a strong desire to manipulate magnetism at timescales below the picosecond. There is therefore a high motivation in studying ultrafast magnetism at the nanoscale. LÄS MER
2. Ultrafast Structural Changes in a Bacterial Photosynthetic Reaction Center probed with XFEL Radiation
Sammanfattning : Photosynthesis is the process by which plants and many species of bacteria convert energy from sunlight into chemical energy used to power their metabolism. As these plants and bacteria are eaten, the chemical energy moves up the food chain and thus photosynthesis provides fuel for almost all life on Earth. LÄS MER
3. FPGA-based Instrumentation for Advanced Physics Experiments
Sammanfattning : Modern physical experiments often demand advanced instrumentation based on advances in technology. This work describes four instrumentation physics projects that are based on modern, high-capacity Field-Programmable Gate Arrays, making use of their versatility, programmability, high bandwidth communication interfaces and signal processing capabilities.

4. X-ray free-electron laser based methods for structural and ultrafast dynamics studies of a photosynthetic reaction centre
Sammanfattning : Life on earth is fuelled by the energy of sunlight, which must first be captured and converted into a chemical energy form useful to the cell. This process is known as photosynthesis and the major pathway of this energy conversion is via photosynthetic reaction centres. LÄS MER
5. Coherent Diffractive Imaging with X-ray Lasers
Sammanfattning : The newly emerging technology of X-ray free-electron lasers (XFELs) has the potential to revolutionise molecular imaging. XFELs generate very intense X-ray pulses and predictions suggest that they may be used for structure determination to atomic resolution even for single molecules. LÄS MER
