  1. 11. Development of a DC Beam Model for the First Prototype of the ESS Virtual Machine

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

    Author : Benjamin Bolling; [2019]
    Keywords : Particle; Accelerator; Beam; Physics; Science; Virtual Machine; Virtual; Machine; Physics and Astronomy;

    Abstract : The European Spallation Source is currently under construction in Lund, Sweden. Consisting of a linear accelerator delivering an unprecedented 5 MW proton beam to the spallation source, i.e. READ MORE

  3. 12. The Potential of Intra-fraction Monitoring of Patient Anatomy Using a Parameterized Motion Model

    University essay from Umeå universitet/Institutionen för fysik

    Author : Maya Staneva; [2019]
    Keywords : ;

    Abstract : Radiotherapy aims to strike a tumour with high accuracy, but anatomic changes and internal organ motion introduce uncertainties and therefore large margins are conventionally used to compensate for this. The MR-Linac will enable target tracking prior to and during treatment which will make daily adjustments of a treatment plan possible. READ MORE

  4. 13. Can Surface Scanning Improve the Workflow of Elekta Linac Treatments?

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Anna Arousell; Ylva Engdahl; [2019]
    Keywords : Elekta Linac; Elekta VersaHD; Elekta Infinity; C-RAD; Catalyst; radiotherapy; surface scanning; workflow analysis;

    Abstract : The aim of the project was to compare the workflow for an Elekta Linac with and without the surfacescanning system Catalyst and describe pros and cons with both workflows. The findings in the reportcan be used as decision support in development of Elekta products and workflow improvements. READ MORE

  5. 14. Designing radiation protection for a linear accelerator : using Monte carlo-simulations

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jonatan Lindahl; [2019]
    Keywords : linac; linear accelerator; accelerator; mega voltage photons; spectra determination; high energy photons; Monte carlo; simulations; radiation transport; dose; radiation; radiation protection;

    Abstract : The department of Radiation Sciences at Umeå University has obtained an old linear accelerator, intended for educational purposes. The goal of this thesis was to find proper reinforced radiation protection in an intended bunker (a room with thick concrete walls), to ensure that the radiation outside the bunker falls within acceptable levels.

  6. 15. Study of an Alternative Pion Collector Scheme for the ESS Neutrino Super Beam Project

    University essay from Uppsala universitet/FREIA

    Author : Patrik Simion; [2019]
    Keywords : FLUKA; flair; FREIA; particle physics; essnusb; beam; collector; pion; neutrino; super beam; ESS;

    Abstract : The ESSnuSB will produce a high intensity neutrino super beam based on the 3 ms long proton pulses at 14 Hz from the ESS linac. With the use of a conventional normal-conducting van der Meer horn, to collect pions from the neutrino target, these 3 ms pulses will have to be compressed to of the order of 1 microsecond in order to avoid overheating of the magnet current conductors.
