1. Beam-Based Error Identification and Correction Methods for Particle Accelerators
Sammanfattning : Modern particle accelerators have tight tolerances on the acceptable deviation from their desired machine parameters. The control of the parameters is of crucial importance for safe machine operation and performance. This thesisfocuses on beam-based methods and algorithms to identify and correct errors in particle accelerators. LÄS MER
2. Optics Corrections and Stabilization Methods for Particle Accelerators
Sammanfattning : The discovery of a Higgs-like particle is the result of excellent performance ofboth the LHC (Large Hadron Collider) and its detectors. A significant partof the success can be attributed to the excellent control of the optics in theaccelerator. In this thesis the methods used to correct the optics functions arepresented. LÄS MER
3. Beam Momentum Changes due to Discharges in High-gradient Accelerator Structures
Sammanfattning : The key questions left unanswered by the Standard Model, and the recent discovery of a Standard Model-like Higgs boson, demand an extension of the research on particle physics to the TeV energy scale. The Compact Linear Collider, CLIC, is a candidate project to achieve such goal. LÄS MER
4. Dosimetric effects of removing the flattening filter in radiotherapy treatment units
Sammanfattning : The aim of this work was to investigate the dosimetric effects of removing the flattening filter from conventional C-arm medical linear accelerators. In conventional linear accelerators used for radiotherapy, a flattening filter is positioned in the beam line to provide a uniform lateral dose profile at a specified depth in water. LÄS MER
