  2. 2. Nonlinear Beam Physics

    University dissertation from Lund University , Department of physics

    Author : Benjamin Folsom; [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; Roger Ruber; Volker Ziemann; Klaus Leifer; Stephen Peggs; [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; [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. Mixed Beam Dosimetry - From Reactor Core to BNCT Patient

    University dissertation from Per Munck af Rosenschöld, Dept. of Radiation Physics, Klinikg. 7, 22185 LUND, SWEDEN

    Author : Per Munck af Rosenschöld; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; BNCT; dosimetry; radiotherapy; mixed beam; quality assurance; in vivo dosimetry; Monte Carlo; ionization chamber; foil activation; MCNP; beam quality correction factor; photon transmission.; Nukleärmedicin; radiobiology; Nuclear medicine; radiobiologi; Radiofarmaceutisk teknik; Radiopharmaceutical technology;

    Abstract : Accurate radiation dosimetry is of paramount importance in order to ensure safe delivery of radiotherapy, and for the possibility of meaningful evaluation of clinical trials, as the radiation absorbed dose is correlated to tissue response. The aim of the studies described in this thesis was to investigate and devise novel approaches to mixed beam dosimetry in boron neutron capture therapy (BNCT). READ MORE
