1. Improving polarizing neutron optics by introducing 11B4C as interlayers
University essay from Linköpings universitet/TunnfilmsfysikAbstract : In this report, the effects of adding 11B4C as interlayers into Fe/Si multilayers is studied. Fe/Si multilayers are commonly used for neutron polarization at large research facilities, and improving the polarizing properties would improve their efficiency. READ MORE

2. Automatic Interpretation of Ion Beam Measurements of Walls in Fusion Machines
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The purpose of this study is to investigate whether it is possible to automatically interpret theresults of Time-of-flight Elastic Recoil Detection Analysis (ToF-ERDA). And if so, find out if the automaticinterpretation is quicker and/or more accurate than the current approach that consists of manualanalysis. READ MORE

3. Fabrication and characterizationof self-supporting Yttrium foils
University essay from Uppsala universitet/Institutionen för fysik och astronomiAbstract : In this project self-supporting foils with focus on the element yttriumhave been fabricated by means of evaporation and magnetron sputtering.The goal was to see if it was possible to make photochromic selfsupportingyttrium foils. Multiple self-supporting foils were made andsome had suitable properties to be further investigated. READ MORE

4. Accelerator-Based Analysis of Rough Wall Materials From Fusion Devices
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Time of Flight - Elastic recoil detection analysis (ToF-ERDA) is a method used to analyse the composition of wall samples from fusion devices. All current analysing software for ToF-ERDA assumes that the target is perfectly flat which could create inaccuracies when rough surfaces are analysed. READ MORE

5. Data Processing in Accelerator-Based Analysis of Wall Materials From Controlled Fusion Devices
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The goal for this project was to analyze and understand the noise of the ion beam analysis technique, Elastic Recoil Detection Analysis (ERDA). This was done by examining two models: Classical models and a prediction model. The prediction model is a parameterized noise distribution model. READ MORE
