1. Momentum-space dynamics of runaway electrons in plasmas
Sammanfattning : Fast electrons in a plasma experience a friction force that decreases with increasing particle speed, and may therefore be continuously accelerated by sufficiently strong electric fields. These so-called runaway electrons may quickly reach relativistic speeds. LÄS MER
2. Synchrotron radiation from runaway electrons in plasmas
Sammanfattning : Highly relativistic runaway electrons are of great concern in the area of fusion energy research, since their presence in tokamak plasmas have the potential to hinder the successful and stable operation of the device, and potentially cause severe structural damage. In this thesis, runaway electron generation dynamics is investigated using the newly developed efficient computational tool CODE. LÄS MER
3. Using life cycle assessment to support the development of electrified road vehicles. Component data models, methodology recommendations and technology advice for minimizing environmental impact
Sammanfattning : The anthropogenic pressure on the Earth system already overshoots safe limits for climate change, so there is an urgent need to drastically reduce greenhouse gas emissions caused by transportation. Electric propulsion technology is a promising solution that can decouple fossil fuel use from road vehicle traffic. LÄS MER
4. Inactivation, Cell Injury and Growth of Microorganisms Exposed to Pulsed Electric Fields Using a Continuous Process
Sammanfattning : Pulsed electric fields (PEF) is a proven technology to inactivate microorganisms under non-thermal conditions. The PEF technology has a potential as a "quality friendly" alternative to traditional methods of food preservation. LÄS MER
5. Risk Analysis of Intentional Electromagnetic Interference on Critical Infrastructures
Sammanfattning : Our modern society depends on the functioning and interplay of a wealth of infrastructures. Practicallyall of these infrastructures are in some form or another, dependent on electrical and electronicsystems. LÄS MER
