6. Synchrotron Radiation, Adsorption Isotherms and the Large Hadron Collider Vacuum System
Sammanfattning : In circular particle accelerators and storage rings with relativistic beams of particles, e.g. electrons or protons, the vacuum performance of the accelerator is determined by the outgassing from the walls of the beam vacuum chamber. LÄS MER
7. Probing and improving coherence in Free-electron lasers
Sammanfattning : Free electron lasers or FELs, have transformed the way science has been done in the last decades by providing coherent, highly brilliant radiation at wavelengths not achievable with conventional lasers. Their most important characteristic, along side brightness, is their coherence, which allows users to perform experiments that rely on precise phase characteristics of the probing radiation. LÄS MER
8. Adsorption isotherms of H2 and mixtures of H2, CH4, CO and CO2 on copper plated stainless steel at 4.2 K and the large hadron collider vacuum system
Sammanfattning : .... LÄS MER
9. High Power Radio Frequency Solid-State Amplifiers and Combiners for Particle Accelerators : From module to system design approach
Sammanfattning : The rise of Big Science projects brings issues related to the energy consumption and the associated environmental impacts of such large-scale facilities. Therefore, environmentally-sustainable developments are undertaken towards the adoption of energy savings and improved energy-efficient approaches. LÄS MER
10. Controlled Trapping in Laser Wakefield Accelerators
Sammanfattning : Experimental studies of laser-driven acceleration of charged particles, in particular electrons and protons, are described in this dissertation. Tightly focused femtosecond laser pulses with intensities exceeding 1018 W/cm2 were used to accelerate charged particles to high energies over distances of a few millimeters. LÄS MER
