1. Electron beam sizes and lifetimes at MAX II and MAX III
Sammanfattning : The MAX II and MAX III synchrotron light sources at MAX-lab provide synchrotron radiation for experiments in a wide variety of research fields. The synchrotron radiation is emitted by ultra-relativistic electrons circulating in electron storage rings. LÄS MER
2. 3D Electron Diffraction : Application and Development towards High-quality Structure Determination
Sammanfattning : Electron crystallography has been proven to be effective for structure determination of nano- and micron-sized crystals. In the past few years, 3D electron diffraction (3DED) techniques were used for the structure solution of various types of complex structures such as zeolites, metal-organic frameworks (MOF) and pharmaceutical compounds.

3. Modeling of Electron Cooling : Theory, Data and Applications
Sammanfattning : The Vlasov technique is used to model the electron cooling force. Limitations of the applicability of the method is obtained by considering the perturbations of the electron plasma. LÄS MER
4. Studies on high brightness electron beams for short pulses and free electron laser
Sammanfattning : Accelerator based lightsources are one of the most powerful tools today for producing high intensity radiation at very short wavelengths. While synchrotron storage rings provide a high average brilliance in a wide wavelength range, the next generation of lightsources aim towards producing ultra-short pulses in the X-ray regime. LÄS MER
5. Material Development for Electron Beam-based Powder Bed Fusion
Sammanfattning : Electron beam powder bed fusion (PBF-EB) is an additivemanufacturing (AM) method based on layer-by-layer melting of apowder bed. The technology is industrialized in certain applicationsbut still considered as immature and is not as widely used as laserbeam-based systems (PBF-LB). LÄS MER
