1. 1. Instrumentation for silicon tracking at the HL-LHC

   Detta är en avhandling från Stockholm : Department of Physics, Stockholm University

   Författare :Rebecca Carney; Samuel Silverstein; Sara Strandberg; Thomas Schön; [2017]
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Instrumentation; physics; particle physics; atlas; radiation damage; neuromorphic; kalman filter; Physics; fysik;

   Sammanfattning : In 2027 the Large Hadron Collider (LHC) at CERN will enter a high luminosity phase, deliver- ing 3000 fb 1 over the course of ten years. The High Luminosity LHC (HL-LHC) will increase the instantaneous luminosity delivered by a factor of 5 compared to the current operation pe- riod. LÄS MER

   Sammanfattning : This thesis presents two measurements of the top quark pair production cross section at sqrt{s} = 1.96 TeV using data from the DØ experiment. Both measurements are performed in the dilepton final state and make use of secondary vertex b-tagging. LÄS MER

5. 4. The microdosimetric variance-covariance method used for beam quality characterization in radiation protection and radiation therapy

   Detta är en avhandling från Stockholm : Medicinsk strålningsfysik (tills m KI)

   Författare :Jan Erik Lillhök; Lennart Lindborg; Bernd Grosswendt; [2007]
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ionizing radiation; radiation quality; radiation protection; radiation therapy; microdosimetry; nanodosimetry; variance-covariance method; MEDICINE Physiology and pharmacology Radiological research Radiological physics; MEDICIN Fysiologi och farmakologi Radiologisk forskning Radiofysik; medicinsk strålningsfysik; Medical Radiation Physics;

   Sammanfattning : Radiation quality is described by the RBE (relative biological effectiveness) that varies with the ionizing ability of the radiation. Microdosimetric quantities describe distributions of energy imparted to small volumes and can be related to RBE. LÄS MER

7. 5. Simulation and analysis of radiation from runaway electrons

   Detta är en avhandling från Stockholm : Medicinsk strålningsfysik (tills m KI)

   Författare :Mathias Hoppe; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; synthetic diagnostics; fusion; plasma physics; synchrotron radiation; tokamak; bremsstrahlung; runaway electrons;

   Sammanfattning : Electron runaway constitutes one of the primary threats to future tokamak fusion reactors such as ITER. Successful prevention and mitigation of runaways relies on the development of theoretical models which accurately describe the dynamics of runaway electrons, and these models must in turn be validated in experiments.
