1. 1. Sensorless Field-Oriented Control and Position Estimation

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Roberts Bitenieks; Lars Brander; [2023]
   Keywords : Sensorless rotor position estimation; High-frequency injection; Technology and Engineering;

   Abstract : This master's thesis investigates the feasibility of implementing field-oriented control for a BLDC motor without relying on a position sensor from a standstill up to 400 rad/s. To achieve this objective, various approaches were used at standstill and high speeds. READ MORE

3. 2. MANGO - Generating 2D-Magnetic Field Maps From Normal-Conducting Magnets Of Experimental Areas

   University essay from KTH/Fysik

   Author : Ambre Visive; [2023]
   Keywords : Applied Physics; Particle Physics; MANGO; Magnetic Field Maps; Normal-Conducting Magnets; Finite-Element Modelling; Opera-2D; Git Repository; Python Package; Beam Lines; Experimental Areas; CERN; Tillämpad Fysik; Partikelfysik; MANGO; Magnetfältskartor; Normalkonduktiva Elektromagneter; Finit Elementmodellering; Opera-2D; Git Repository; Python Package; Partikelstrållinje; Experimentområden; CERN;

   Abstract : This thesis discusses the development of MANGO, a tool created to model normal-conducting magnets which were installed in the 1970s in the experimental areas at CERN, and store their analysis. MANGO formulates an answer to two problems faced by the physicists of the Beam Department when they model a beam line: first, how to produce new magnetic field maps and, second, how to easily access existing ones? It contains a multi-use package that offers an automated process to produce magnetic field maps from finite-element models of magnets. READ MORE

4. 3. Combustibility study of resin for warm magnet coils used at CERN

   University essay from Lunds universitet/Avdelningen för Brandteknik

   Author : Juan Carlos Lopez Santiago; [2023]
   Keywords : Epoxy resin; flammability; radiation; aging; cone calorimeter; micro combustion calorimeter; thermogravimetric analysis; lateral ignition and flame spread test; chemical composition of polymers; polymers; epoxy composite; polymer composite; failure of epoxy resins; magnetic coil; Technology and Engineering;

   Abstract : CERN is the world's largest particle physics laboratory, housing multiple accelerators that rely heavily on magnetic coils. These coils are integral to the generation of powerful magnetic fields essential for particle accelerator experiments, detectors, and other equipment. READ MORE

5. 4. Phase Unwrapping MRI Flow Measurements

   University essay from Uppsala universitet/Avdelningen Vi3

   Author : Mio Liljeblad; [2023]
   Keywords : phase unwrapping; computer vision; cine MRI; NMR; flow measurements; velocity encoding; venc; energy minimization; magnetic resonance; cardiac MRI; sinotubuar junction; pulmonary artery; ascending descending aorta; laplacian algorithm; iterative graph cuts; IGC; sequential tree-reweighted message passing; TRW-S; velocity to noise ratio; VNR; retrospective wrapping; energy formulation;

   Abstract : Magnetic resonance images (MRI) are acquired by sampling the current of induced electromotiveforce (EMF). EMF is induced due to flux of the net magnetic field from coherent nuclear spins with intrinsic magnetic dipole moments. READ MORE

6. 5. Hybrid Simulations of Solar Wind Plasma Interaction with the Lunar Reiner Gamma Magnetic Anomaly

   University essay from Umeå universitet/Institutionen för fysik

   Author : David Frisk Strömberg; [2023]
   Keywords : ;

   Abstract : The Moon has small scale regions of strong magnetic fields scattered over its surface, known as crustal fields. Coexisting with some of the strongest crustal fields are peculiar markings in the lunar soil, called lunar swirls, which are suggested to be formed by magnetosphere-like interactions between the crustal fields and the solar wind plasma.
