1. 1. Computational investigation of the feasibility touse solid neon moderation for GBAR

   University essay from Stockholms universitet/Fysikum

   Author : Lars Gehrmann; [2023]
   Keywords : ;

   Abstract : The main goal of the GBAR (Graviational Behaviour of Antihydrogen at Rest) experiment is to investigatethe gravitational effect on antimatter by measuring the classical free fall of an antihydrogen atom. The requiredpositrons are created by pair production inside a tungsten target and are moderated using a tungsten mesh. READ MORE

3. 2. Design of cooling-air permeable coil support

   University essay from KTH/Hållfasthetslära

   Keywords : Topology optimization; FEM-simulations; CFD-simulations; Material selection; Topologioptimering; FEM-simuleringar; CFD-simuleringar; Materialval;

   Abstract : Coil supports are integral load-bearing components employed in generators andmotors. They serve the purpose of preventing excessive deformation and maintaininga stable position of the coils responsible for generating power and magnetic fieldswhen rotating. READ MORE

4. 3. Reducing Power Losses by Optimizing Cooling in Final Annealing of Non-Oriented Electrical Steel

   University essay from KTH/Materialvetenskap

   Author : Emil Rosqvist; [2023]
   Keywords : ;

   Abstract : Surahammars Bruks AB produces non-oriented electrical steel used in several types of motors and generators. Because of recent years exponentially growing market for electrical vehicles, non-oriented electrical steel used in electrical vehicle motors is becoming an increasingly important product. READ MORE

5. 4. Additively Manufactured Rare Earth Free Permanent Magnets

   University essay from Uppsala universitet/Tillämpad materialvetenskap; Uppsala universitet/Oorganisk kemi

   Author : Himesha Abenayake; [2023]
   Keywords : additive manufacturing; MnAl; MnAl C ; rare earth free permanent magnets; selective laser melting; SLM; MnAl-based permanent magnets;

   Abstract : It’s well known that MnAl(C) material consists of a metastable phase (τ) with promising ferromagnetic properties, produced either by controlled cooling from the high-temperature hexagonal ε-phase or rapid cooling that freezes the ε-phase followed by low-temperature annealing. Due to the high cooling rates involved, additive manufacturing (AM) especially selective laser melting (SLM), has been identified as a possible method to retain the high-temperature ε-phase, hence containing a potential capacity to produce permanent magnets upon low-temperature annealing.

6. 5. Theoretical and experimental investigation of themagneto-optical eect in graphene in the THz region

   University essay from Uppsala universitet/FREIA

   Author : Mircea-George Coman; [2022]
   Keywords : ;

   Abstract : In many optics applications we need lenses with dynamically tunable focal lengths. One design of such a lensis developed in and it relies on the magneto-optical eect. In this design, a graphene layer is placed ina magnetic eld that varies quadratically in space. READ MORE
