  1. 1. Radiation Effects on GaN-based HEMTs for RF and Power Electronic Applications

    University essay from KTH/Tillämpad fysik

    Author : Wilhelm Holmberg; [2023]
    Keywords : High Electron Mobility Transistor; HEMT; Gallium Nitride; GaN; Silicon Carbide; SiC; Proton Radiation; Galliumnitrid; GaN; Kiselkarbid; SiC; Kisel; Si; HEMT; Transistor; Protonstrålning;

    Abstract : GaN-HEMTs (Gallium Nitride-based High Electron Mobility Transistors) have, thanks to the large band gap of GaN, electrical properties that are suitable for applications of high electrical voltages, high currents, and fast switching. The large band gap also gives GaN-HEMTs a high resistance to radiation. READ MORE

  3. 2. Modelling the evolution of an ion beam through a 3 MV Pelletron accelerator

    University essay from Lunds universitet/Kärnfysik

    Author : Niek van Woudenberg; [2021]
    Keywords : accelerator modelling; ion-beam transport; Pelletron simulation; 3D simulation; cross-validation; Physics and Astronomy;

    Abstract : In this work simulations of the LIBAF Pelletron were performed to gain insight into the parameters that govern the machine operation and control. Three simulation packages: COMSOL, WARP and TURTLE/TRANSPORT were employed, and cross-validation of these software packages was performed by test-case simulations. READ MORE

  4. 3. The Channeling Effect in Ultra-Thin dE-E Monolithic Silicon Telescopes

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

    Author : Fredrik Parnefjord Gustafsson; [2017]
