1. 1. Prospects for a Free Electron Laser at the FemtoMAX Beamline

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Johan Holmberg; [2024]
   Keywords : Free Electron Lasers; FEL; synchrotron radiation; MAX IV; FemtoMAX; GENESIS 1.3; XFEL; X-rays; soft X-rays; Physics and Astronomy;

   Abstract : A Free Electron Laser (FEL), is a device that generates extremely coherent and brilliant radiation using electrons accelerated to relativistic velocities in a particle accelerator. The process utilises similar equipment to what is used at a synchrotron source like MAX IV, but in addition there is an interaction between the relativistic electron beam and the generated radiation to achieve an exponential growth in radiation intensity.

3. 2. Determination of the inelastic mean freepath for SiO2 and the BBL polymer : A study with XPS and HAXPES

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Rickard Gauffin; [2022]
   Keywords : XPS; HAXPES; IMFP; Polymer;

   Abstract : This study targets methodology development using Photoelectron Spectroscopy (PES) as a tool for investigating material surfaces. When analysing samples with X-ray Photoelectron Spectroscopy (XPS) and Hard X-ray Photoelectron Spectroscopy (HAXPES), it is important to know the probing depth of the samples. READ MORE

4. 3. Sample Preparation Optimization for Laboratory Soft X-Ray Microscopy

   University essay from KTH/Tillämpad fysik

   Author : Haya Amer Abduljabar; [2022]
   Keywords : Soft X-rays; Stockholm laboratory soft X-ray microscope; Sample preparation; Nanoparticles; Macrophages; Mjuka röntgenstrålar; Stockholm laboratoriets mjuka röntgenmikroskop; Provberedning; Nanopartiklar; Makrofager;

   Abstract : With the introduction of nanoparticles in health care and daily products, the interaction between cells and nanoparticles is of great interest. There are many ways to examine these interactions, one of them being soft X-ray microscopy. READ MORE

5. 4. Simulating and Testing the Polarimetric Response of the X-ray Polarimetry Telescope XL-Calibur

   University essay from KTH/Fysik

   Author : Filip af Malmborg; [2022]
   Keywords : Astroparticle Physics; Astrophysics; Detector Physics; Simulation; Theoretical Physics; Engineering Physics; Astropartikelfysik; Astropartikelfysik; Detektorfysik; Simulering; Teoretisk Fysik; Teknisk Fysik;

   Abstract : X-ray polarimetry, the study of the polarisation of X-ray light, is a powerful and rapidly developing tool for astrophysics, which promises to help answer outstanding questions about the physics of extreme objects such as pulsars, X-ray binaries and active galactic nuclei. The balloon-borne telescope XL-Calibur will be the first instrument to study the polarisation of hard X-rays (with energies between 10 and 100 keV) in detail, correlating with the soft X-ray observations of IXPE to provide further tests of polarisation-dependent x-ray emission models in extreme objects.

6. 5. Synchrotrons as a Source for Soft X-Ray Lithography

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Thomas Joseph Grandsaert Jr; [2021]
   Keywords : Physics and Astronomy;

   Abstract : To move to lower modes in extreme ultra-violet lithography (EUVL) technology (and keep up with Moore’s law), new sources of soft X-ray radiation must be developed. It is clear from previous studies that Free Electron Lasers (FELs) can easily meet the in-band power requirements at these lower wavelength modes, however detailed studies for insertion devices (undulators) as a soft X-ray lithography (SXL) source are due for a re-evaluation.
