  1. 1. Prospects for a Free Electron Laser at the FemtoMAX Beamline

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

    Author : Johan Holmberg; [2024]
    Keywords : Free Electron Lasers; FEL; synchrotron radiation; MAX IV; FemtoMAX; GENESIS 1.3; XFEL; X-rays; soft X-rays; Physics and Astronomy;

    Abstract : A Free Electron Laser (FEL), is a device that generates extremely coherent and brilliant radiation using electrons accelerated to relativistic velocities in a particle accelerator. The process utilises similar equipment to what is used at a synchrotron source like MAX IV, but in addition there is an interaction between the relativistic electron beam and the generated radiation to achieve an exponential growth in radiation intensity.

  3. 2. Combustibility study of resin for warm magnet coils used at CERN

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Juan Carlos Lopez Santiago; [2023]
    Keywords : Epoxy resin; flammability; radiation; aging; cone calorimeter; micro combustion calorimeter; thermogravimetric analysis; lateral ignition and flame spread test; chemical composition of polymers; polymers; epoxy composite; polymer composite; failure of epoxy resins; magnetic coil; Technology and Engineering;

    Abstract : CERN is the world's largest particle physics laboratory, housing multiple accelerators that rely heavily on magnetic coils. These coils are integral to the generation of powerful magnetic fields essential for particle accelerator experiments, detectors, and other equipment. READ MORE

  4. 3. Simulation and Testing of a MU-MIMO Beamforming System

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

    Author : Nazyar Mehdishishavan; Zonghan Wang; [2023]
    Keywords : Multi-User Multiple-Input Multiple-Output MU-MIMO ; Beamforming; Sounding Reference Signal SRS ; Reciprocity-based; Butler matrix; Advanced Antenna System AAS ; Technology and Engineering;

    Abstract : Multi-User Multiple-Input Multiple-Output (MU-MIMO) technology has become increasingly important in the field of wireless communication due to its ability to highly increase the capacity and efficiency of wireless networks [1]. Beamforming, as a technique used in MU-MIMO systems, improves network performance by improving signal quality and reducing interference. READ MORE

  5. 4. Investigation of Ion Extraction Anomalies at TwinEBIS

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Niek van Woudenberg; [2023]
    Keywords : CERN; ISOLDE; Ion Source; EBIS; REXEBIS; TwinEBIS; Ion losses; Charge Breeding; Ion Extraction; CST Studio Suite; Physics and Astronomy;

    Abstract : The electron beam ion source REXEBIS at CERN-ISOLDE delivers highly-charged ra- dioactive ions for post-acceleration in the HIE-ISOLDE LINAC. Research and develop- ment of components for electron beam ion sources is carried out at the TwinEBIS test stand, currently equipped with a Brillouin electron gun called MEDeGUN. READ MORE
