    Abstract : Digital communication through communication platforms has increased and changed significantly during the last decade and recently not least because of the corona pandemic, which has shifted many face-to-face activities to the internet (Obringer R. , et al., 2021). READ MORE

  4. 13. Determination of Proton Beam Waist Positions Using Beam Position Monitors

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB; Lunds universitet/Synkrotronljusfysik

    Author : Gustav Gird Fahlström; [2022]
    Keywords : ESS; European Spallation Source; Proton beam; waist; BPM; Method; transverse; beam dynamics; beam physics; Lattice Error; Matrix formalism; Python; trajectory simulation; physics; Physics and Astronomy;

    Abstract : In this work, we examine a novel method for the determination of proton beam waist locations using beam position monitors. Based on the lattice of the final transport line section of the European Spallation Source linac, a simplified version of the beam line composed of quadrupole magnets and correctors is constructed in Python using a matrix formalism.

  5. 14. Air and Silicon resistivity design space for dielectric simulations

    University essay from

    Author : Oscar Hammarberg; Anton Larsson; Adam Steiner; [2022]
    Keywords : electrical bushings; simulations; humidity; electrical breakdown; corona discharge; comsol multiphysics;

    Abstract : Electrical bushings are a type of hollow or solid conductor withinsulation designed to allow a conductor to pass through a conductingbarrier without making electrical contact and are very important forsafe transportation of electricity. The bushings vary in size, but allbushings have a solid or hollow conductor. READ MORE
