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. Evaluation of Computer Tomography based Cancer Diagnostics with the help of 3D Printed Phantoms and Deep Learning

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Alex Back; Pontus Pandurevic; [2023]
   Keywords : Machine Learning; Deep Learning; Convolutional Neural Networks; Perception Loss; CNN; DL; ML; Computer Tomography; CT; Cancer Diagnostics; Evaluation of Image Reconstruction; Radiomics; Tumors; 3D Printed Phantoms; 3D Printing; PLA;

   Abstract : Computed x-ray tomography is one of the most common medical imaging modalities andas such ways of improving the images are of high relevance. Applying deep learningmethods to denoise CT images has been of particular interest in recent years. READ MORE

4. 3. 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

5. 4. 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

6. 5. Image analysis on the structure of the Achilles tendon

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Linnea Andersson; [2022]
   Keywords : biomechanics; Achilles tendon; image analysis; image processing; tendons; synchrotron; computed tomography; phase contrast; Technology and Engineering;

   Abstract : The Achilles tendon is the largest tendon of the human body which makes injuries of it very painful and incapacitating. A common factor of the pain are heterotopic ossifications, which are mineral deposits occurring inside the normal tendon tissue. Why and how heterotopic ossifications occur are somewhat unknown.
