1. 1. Properties of the Optical Hot Spots in the Circumstellar Ring of SN 1987A

   University essay from KTH/Fysik

   Author : Christos Tegkelidis; [2023]
   Keywords : ;

   Abstract : The proximity of Supernova 1987A provides a great opportunity to study the aftermath of the impact of the ejecta with the dense clumps (observed as ”hot spots”) located in the equatorial circumstellar ring. This thesis examines the properties of the clumps by using Hubble Space Telescope optical imaging taken with the F625W and F675W broad filters between 1994 and 2022. READ MORE

3. 2. 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
