  2. 2. Nonlinear Beam Physics

    University dissertation from Lund University , Department of physics

    Author : Benjamin Folsom; Lund University.; Lunds universitet.; [2019-03-30]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nonlinear dynamics; Beam dynamics; Accelerator Physics; space charge; Accelerator magnets; simulations multi-particle dynamics;

    Abstract : A condensed treatment of conventional beam physics (both linear and nonlinear) is given for the non-expert; this constitutes a minimum knowhow for constructing simulations of rudimentary beamlines. The criteria for an ideal nonlinear charged-particle simulation algorithm are then presented, leading to the derivation of a symplectic, explicit, Lorentz-covariant integrator. READ MORE

  3. 3. Beam Diagnostics and Dynamics in Nonlinear Fields

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jim Ögren; Uppsala universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Beam diagnostics; Nonlinear beam dynamics; Accelerator physics;

    Abstract : Particle accelerators are indispensable tools for probing matter at the smallest scales and the improvements of such tools depend on the progress and understanding of accelerator physics. The Compact Linear Collider (CLIC) is a proposed, linear electron–­positron collider on the TeV-scale, based at CERN. READ MORE

  4. 4. Direct writing with an MeV proton beam: Development and Applications

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Vaida Auzelyte; Lund University.; Lunds universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; direct writing; beam control; Physics; Fysik; Teknik; Technological sciences; proton beam; lithography; Fysicumarkivet A:2006:Auželytė;

    Abstract : This thesis presents work aimed at the development and application of a new lithography system for direct material patterning with the MeV proton beam at the Lund Nuclear Microprobe (NMP) facility. MeV proton beams are advantageous for use as a patterning tool due to their deep and well defined penetration through matter and their highly local energy deposition. READ MORE

  5. 5. Robust Formulations for Beam-to-Beam Contact

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Hamid Reza Motamedian; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structures; Finite Element Methods; Solid Mechanics; Hållfasthetslära;

    Abstract : Contact between beam elements is a specific category of contact problems which was introduced by Wriggers and Zavarise in 1997 for normal contact and later extended by Zavarise and Wriggers to include tangential and frictional contact. In these works, beam elements are assumed to have rigid circular cross-sections and each pair of elements cannot have more than one contact point. READ MORE
