  1. 1. Design of an X-ray transfer beamline for the Soft X-ray project at MAX IV

    University essay from

    Author : Milad Emadi; Sofia Tynelius; Patric Beas Peterson; Johnny Ljung; [2019]
    Keywords : optics; focusing; beam; x-ray; MAX-IV; soft x-ray; transfer; matrix;

    Abstract : At the MAX-IV lab in Lund, there is a current goal to build a new soft X-Ray laser. The beam will be generated from a free-electron laser (FEL), which is an instrument consisting of high-speed electrons. The electrons move through alternating magnetic fields, causing the beam to become monochromatic. READ MORE

  3. 2. Modelling of injection of electrons by low-dimensional nanowire into a reservoir

    University essay from Linköpings universitet/Teoretisk Fysik

    Author : Ivan Yakymenko; [2018]
    Keywords : quantum wire; magnetic electron focusing; electron flow; electron injector and detector; semiconductor heterostructure; two-dimensional electron gas;

    Abstract : High-mobility two-dimensional electron gas (2DEG) which resides at the interface between GaAs and AlGaAs layered semiconductors has been used experimentally and theoretically to study ballistic electron transport. The present project is motivated by recent experiments in magnetic electron focusing. READ MORE

  4. 3. 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

  5. 4. Touschek- and Gas Scattering Lifetime Investigations in the MAX IV 3 GeV Storage Ring

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

    Author : Jens Sundberg; [2017]
    Keywords : Lifetime; Scraper; Scattering; MAX IV; Touschek; Storage Ring; Synchrotron; Physics and Astronomy;

    Abstract : The MAX IV 3 GeV storage ring is a fourth-generation electron synchrotron. At the time of writing in May 2017, it is the lowest emittance light source in the world. To study its performance is of foremost importance for the MAX IV Laboratory, its users and for upcoming synchrotrons. READ MORE
