  1. 6. Tuning of the ESS Drift Tube Linac using Machine Learning

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB

    Author : Johan Lundquist; [2022]
    Keywords : Accelerator; drift tube linac; machine learning; neural network; ESS; linac; tuning; proton; longitudinal dynamics; beam physics; Physics and Astronomy;

    Abstract : The European Spallation Source, currently under construction in Lund, Sweden, will be the world's brightest neutron source. It is driven by a linear accelerator designed to accelerate a beam of protons with 62.5 mA, 2.86 ms long pulses, working at 14 Hz. READ MORE

  3. 7. Nuclear Structure near the Proton Drip-line: A Search for Excited States in 62Ge

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

    Author : Dalia Farghaly; [2022]
    Keywords : nuclear physics; nuclear structure; proton drip-line; excited states; germanium; fusion-evaporation reaction; experimental nuclear physics; gamma sphere; gamma spectroscopy; HPGe detectors; data analysis; Physics and Astronomy;

    Abstract : An experiment to study mirror symmetry in the mass A = 60 region was performed at the Argonne National Laboratory (ANL) in 2020. The fusion-evaporation reaction 40Ca + 24Mg → 64Ge* at a beam energy of 106 MeV was used to populate excited states in 62Ge. READ MORE

  4. 8. Verification measurements on MRI-linac with PTW BEAMSCAN MR

    University essay from Umeå universitet/Institutionen för fysik

    Author : Olivia Kvarnlöf; [2022]
    Keywords : ;

    Abstract : In radiotherapy the main goal is to kill cancer cells, prevent them from growing and reproducing, while healthy tissue is spared. One technique to treat cancer is to use external radiotherapy where a linear accelerator (linac) is used to generate a high energy radiation photon beam. READ MORE

  5. 9. Characterization of Radiomics Features Extracted from Images Generated by the 0.35 T Scanner of an Integrated MRI-Linac

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Rebecka Ericsson Szecsenyi; [2020]
    Keywords : Medicine and Health Sciences;

    Abstract : Purpose: In an era of personalized oncology where the aim is to give every patient the right treatment at the right time an area of promising research is emerging called radiomics, or quantitative image analysis. The main underlying hypothesis is that pathophysiological information can be found in image texture not visible to the bare eye that can improve diagnosis, treatment adaption or be linked to a certain clinical outcome.

  6. 10. Numerical modelling of cold helium safety discharges from the cryogenic distribution line

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Jonathan Persson; [2020]
    Keywords : Technology and Engineering;

    Abstract : The European Spallation Source, ESS, is a project currently with 17 Partner Countries, and with Sweden and Denmark as host nations. The ESS main facility is being constructed in Lund, to ultimately become the world’s most powerful neutron source, providing around 30 times brighter neutron beams than any earlier facility. READ MORE
