1. 1. Data Reduction and Analysis with the MPRu instrument for Neutron Emission Spectroscopy at JET

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Steven Hendrik Bijl; [2023]
   Keywords : Fusion; JET; MPRu;

   Abstract : This research project centres on advancing data analysis techniques using the Magnetic Proton Recoil Upgrade Neutron Spectrometer (MPRu) for neutron emission spectroscopy during the deuterium tritium experimental campaign (DTE2) at the Joint European Torus (JET). The study aimed to address three pivotal questions, each with implications for optimizing data accuracy, quality, and utility. READ MORE

3. 2. Use of the JET pedestal database to assess the role of ion temperature and plasma rotation on the discrepancy between ideal peeling-ballooning model and experimental data

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Max Eichenberger; [2022]
   Keywords : Nuclear fusion; Joint European Torus JET ; H-mode; pedestal; Edge-localized-modes ELMs ; Peeling-Ballooning; relative shift; ion temperature; plasma rotation; Kärnfusion; JET Joint European Torus ; H-läge; piedestal; ELM Edge Localized­Modes ; peeling-ballooning; relativ förskjutning; jontemperatur; plasmarotation;

   Abstract : Next-generation and present fusion devices such as the Joint European Torus (JET) aim for plasma operations in H-mode, a plasma regime with high confinement and low loss of energy and fuel that results from a barrier for heat and particle transport at the plasma edge, the pedestal. Due to steep gradients of the density, temperature and pressure profiles, the pedestal experiences instabilities called Edge-localized-modes (ELMs) which lead to large fluxes of heat and particles that might damage machine components.

4. 3. Design of Instrumentation & Control and Optical Table Instruments for the Divertor Flow Monitor Diagnostic at ITER

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Niklas Hermansson; [2022]
   Keywords : Coherence imaging; fusion; optics; plasma diagnostic; polarization; spectroscopy; Zeeman-Doppler imaging;

   Abstract : This master's thesis describes the process of the design and instrument selection for a future optical table, part of a plasma flow monitor diagnostic system at the international thermonuclear experimental reactor, ITER. The diagnostic system is designed to detect the presence of edge localized mode, low to high confinement mode transition of plasma, and plasma flow velocity in the divertor region of the reactor.

5. 4. Modeling of Radio Frequency Heating in JET

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Christos Tegkelidis; Erik Lindström; [2020]
   Keywords : deuterium; energy; FEMIC; fusion; ICRH; JET; radio frequency heating; tritium;

   Abstract : This study examines the efficiency of ion cyclotronresonance heating in multi-ion plasmas in JET (Joint EuropeanTorus), using deuterium and tritium as fuel along with smallconcentrations of a third ion species. In particular, two ionminority scenarios, hydrogen and helium, as well as a 3-ionscenario using beryllium were constructed. READ MORE
