1. 21. Adaptation and Redesign of SPECTRAP Beamline

   University essay from

   Author : Oliver Kraft; Elina Hollsten; [2023]
   Keywords : ;

   Abstract : Replacement of the superconducting magnet used in the SPECTRAP laser spectroscopy experiment at GSI necessitates redesign of some associated components. This thesis investigates a potential new beamline for SPECTRAP using a single pulse drift tube to slow the ions down. READ MORE

3. 22. Electrolytic Reduction of Iron Oxides in Molten Salt with a Mineralogical Investigation of Magnetite Ore of Tapuli

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Elina Fernö; [2023]
   Keywords : Iron reduction; trace element analysis on magnetite ore; molten salt electrolysis; sodium hydroxide electrolyte; NaOH; greenhouse gas; carbon dioxide; CO2; green ironmaking; Järnreduktion; spårelementanalys på magnetitmalm; smältelektrolys; elektrolys i natriumhydroxid; NaOH; elektrolyt; växthusgas; koldioxid; CO2; grön järnframställning;

   Abstract : This master's thesis covers an investigation of the reduction behavior of different iron oxides when electrolytically reduced with molten salt electrolysis (MSE). The tested iron oxides were wüstite (FeO), hematite (Fe2O3), magnetite (Fe3O4) and magnetite ore concentrate from the Tapuli deposit in Pajala, Norrbotten, Sweden. READ MORE

5. 24. Photoluminescence Mapping of Erbium Doped Lithium Niobate

   University essay from KTH/Tillämpad fysik

   Author : Chuanshi Xie; [2023]
   Keywords : Automotive mapping; Erbium emitters; Ion implantation; Lithium niobate on insulator; photoluminescence microscopy; Automatisk kartläggning; Erbium fotonemitterare; Jonimplantation; Litiumniobat på isolator; fotoluminiscensmikroskopi.;

   Abstract : Lithium niobate (LiNbO3) is a human-made crystalline which is widely used in modern photonics due to its useful properties. In recent years, there has been significant progress in the development of lithium niobate on insulator (LNOI) technology, realizing a fully functional photonic integrated circuits, thanks to its capabilities in both electro-optics and second-order optical nonlinearity.

6. 25. Skattning av HGV och stamvolym med data från stereomatchade drönarbilder genom befintliga modeller från Skogliga grunddata

   University essay from SLU/Dept. of Forest Resource Management

   Author : Erik Forslöw; [2023]
   Keywords : drönare; stereofotogrammetri; skogliga grunddata; skogsbruksplanläggning;

   Abstract : Inom den svenska skogsbruksplanläggningen sker idag datainsamlingen traditionellt med subjektivt fördelade relaskopsytor. Den subjektiva mätningen varierar mellan och inom planläggare och har generellt ett relativt medelfel (rRMSE) på 9 % för grundytevägd medelhöjd (HGV) och 15–20 % for volym/ha. READ MORE
