  1. 1. Micrometer Gap Distance Dependence on Temperature Changes in a Large Electrode System

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Simon Lindesvik Warma; Felix Elmgren; [2018]
    Nyckelord :electrode system; capacitance; gap distance;

    Sammanfattning : The purpose of this project is to verify if the so called capacitance method is a sensitive enough method to measure micrometer distance changes in an electrode system. This is done by heating up an electrode system to 60°C and make capacitance measurements during the procedure. LÄS MER

  2. 2. Application of GEANT4 toolkit for simulations of high gradient phenomena

    Kandidat-uppsats, Uppsala universitet/FREIAUppsala universitet/Institutionen för teknikvetenskaper

    Författare :Daniel Persson; [2018]
    Nyckelord :GEANT4; XBox 2; XBox; CERN; CLIC; field emission; vacuum breakdown; dark current; breakdown current; spectrometer; FREIA; accelerator; cavity;

    Sammanfattning : To study electron emissions and dark currents in the accelerating structures in particle colliders, a test facility with a spectrometer has been constructed at CERN. This spectrometer has been simulated in the C++ toolkit GEANT4 and in this project the simulation has been improved to handle new realistic input data of the emitted electrons. LÄS MER

  3. 3. Particle-in-cell simulations of intense laser-matter interactions, with a focus on light ion acceleration

    H-uppsats, Chalmers tekniska högskola/Institutionen för fundamental fysik

    Författare :Joel Magnusson; [2015]
    Nyckelord :;

    Sammanfattning : In conventional accelerators the risk of electrical breakdown limits the electric fieldsused to accelerate charged particles to the order of 100 MV/m. As a result, the acceleratorsare required to be very long in order to achieve particle beams of very high energy. LÄS MER
