1. 1. Calculation of alpha knock-on neutron spectra from the 2021 JET DT campaign

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Arna Ormsdóttir; [2023]
   Keywords : Thermonuclear fusion; DT plasma; neutron spectra; supra-thermal ions;

   Abstract : A python code was developed to compute the alpha knock-on (AKN) neutron spectrum using two already available computational tools. The code was used to calculate the AKN for a given discharge from the DTE2 JET campaign. Results showed that the beam-target contribution dominated the neutron spectra and obscured the AKN tail.

3. 2. Effect of a new pedestal width constraint on the pedestal predictions with Europed in JET fusion plasmas

   University essay from KTH/Energiteknik

   Author : Eleonora Iurlaro; [2022]
   Keywords : ;

   Abstract : As the whole world is facing and will face further challenges in the future in meeting the energy demand, thermonuclear fusion could be part of a future sustainable energy scenario. However, there are still many problems related to fusion that need to be addressed before implementing fusion energy in fusion power plants. READ MORE

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. Type-1 Active Falactic Nuclei and their Supernovae

   University essay from Uppsala universitet/Teoretisk astrofysik

   Author : Inigo Imaz Chacon; [2019]
   Keywords : SN; AGN; supernova; counts; star formation; astronomy; type-1 AGN; obscured; thermonuclear; core-collapsed;

   Abstract : Supernovae (SNe) and more specifically Core-Collapsed SNe (CC SNe) are signatures of on-going star formation (SF), and higher star formation rates. In this project, we perform a study of all SNe ever discovered inside a specific type of galaxy: a type-1 Active Galactic Nucleus (AGN1). READ MORE

6. 5. Heating a Plasma to 100 Million Kelvin

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Gunnar Fröberg; Thomas Nygren; [2014]
   Keywords : ;

   Abstract : In this work techniques for heating the fusion reactor ITER to thermonuclear temperatures, over 100 million kelvin, is investigated. The temperature is numerically computed for different heating configurations. The heat leakage is modeled to occur only via diffusion. The diffusion is assumed to be a combination of Bohm and gyro-Bohm diffusion. READ MORE
