  1. 1. Assisted GNSS Positioning using State Space Corrections

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Oskar Philipsson; [2023]
    Keywords : positioning; GNSS; SSR; EKF; sensor fusion;

    Abstract : Classical GNSS based positioning has accuracy limitations due to many sources oferror. The error sources range from clock errors and orbit errors toerrors due to variations in atmospheric propagation delays. One way to improve GNSSpositioning is to generate real time corrections using a GNSS reference network. READ MORE

  3. 2. Focal Spot Optimization Using Spatial Light Modulation and a Phase Retrieval Algorithm

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

    Author : Robert Petersen; [2023]
    Keywords : Spatial Light Modulation; Phase Retrieval Algorithm; Focal Spot Optimization; Adaptive Optics; Wavefront Sensing; Lasers; Physics and Astronomy; Technology and Engineering;

    Abstract : Aberrations to the wavefront of a laser beam reduce the quality of the focal spot and are generally undesired. This project is aimed at determining the aberrations of laser beams by using a phase retrieval algorithm and to show that it is possible to correct the aberrations with a spatial light modulator to optimize the focal spot.

  4. 3. A Linear Framework for Orbit Correction in the High-Luminosity Large Hadron Collider

    University essay from Lunds universitet/Matematik LTH

    Author : Joel Andersson; [2019]
    Keywords : CERN; HL-LHC; LHC; accelerator physics; orbit correction; error correction; closed orbit; Twiss; beam dynamics; dynamical systems; Python; Mathematics and Statistics;

    Abstract : In a circular accelerator the closed orbit can be viewed as the mean position of particles in a beam. The closed orbit is perturbed by machine errors and can be manipulated by dedicated corrector magnets. READ MORE

  5. 4. Effect of Insertion Devices Tapering Mode of Operation on the MAX IV Storage Rings

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/MAX IV-laboratoriet

    Author : Georgia Paraskaki; [2018]
    Keywords : Science General;

    Abstract : Tapering is a mode of operation of insertion devices that allows the users to perform scanning in a range of photon energies. NanoMAX, BioMAX and BALDER are all beamlines of the 3 GeV MAX IV storage ring and will provide this special mode of operation for their users. READ MORE

  6. 5. Commissioning of the First Insertion Devices on the 1.5 GeV Storage Ring in MAX IV

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Hampus Månefjord; David Hill; [2018]
    Keywords : MAX IV; Accelerator physics; Synchrotron; light source; insertion device; Elliptically Polarized Undulator; EPU; Linear Optics from Closed Orbits; LOCO; beamline commissioning; betatron beat; undulator; wiggler; Technology and Engineering;

    Abstract : When installing an insertion device (ID) in a storage ring the electron beam is affected. The positional displacement and angle deflection is called orbit displacement (OD) and higher order effects such as focusing of the electron beam are referred to as linear optics. READ MORE
