6. On the Challenges for Time-of-Flight Electron Spectroscopy at Storage Rings
Sammanfattning : Time-of-flight (TOF) techniques for energy analysis have been common in electron spectroscopy for many decades. TOF-based electron spectrometers benefit from higher transmission and information rate compared to their main competitor: the hemispherical analyser; the drawback being their lower energy resolution.

7. Higher harmonic cavities at 3rd generation synchrotron light sources
Sammanfattning : Synchrotron radiation is a tool widely used in science. It is produced by electron accelerators called storage rings. With the high performance of the 3rd generation synchrotron light sources, the scientific results are excellent. It is important to identify and overcome the limitations of a storage ring in order to enhance its performance. LÄS MER
8. Compact Soft X-Ray Microscopy: Image Processing and Instrumentation
Sammanfattning : Soft x-ray microscopy is a powerful technique for natural-contrast, high-resolution imaging of organic materials. This Thesis describes new instrumentational and new image-processing methods to improve the image quality of the compact x-ray microscope at the Biomedical & X-Ray Physics division at KTH. LÄS MER
9. Growth and Nano-structural Studies of Metallic Multilayer for X-ray Mirrors
Sammanfattning : A part of the Ph.D. project focused on growth and characterization of metal multilayers is presented in this licentiate thesis. The main interest in carrying out this research is to develop highly reflective normal-incidence condenser mirrors for soft X-ray microscopy studies in the water window (λ=2. LÄS MER
10. Soft X-ray Multilayer Mirrors
Sammanfattning : This thesis is focused on the design, growth and characterization of soft x-ray multilayer mirrors with the emphasis on the wavelength region called the water window (λ=2.4-4.4 nm). LÄS MER
