1. Hollow Cathode Deposition of Thin Films
Sammanfattning : Thin films of metals and compounds have a very wide range of applications today. Many of the deposition methods used for the production of such films utilize plasma to support the growth the film, e.g. by the supply of energy and the enhancement of reactivity. LÄS MER
2. Modelling and Applications of the Hollow Cathode Plasma
Sammanfattning : This thesis presents experimental and modelling research on atmospheric pressure hollow cathodes and hollow electrodes. Experiments with the hybrid hollow electrode activated discharge (H-HEAD), which is a combination of a hollow cathode and a microwave plasma source, is presented. LÄS MER
3. Plasma Enhanced Chemical- and Physical- Vapor Depositions Using Hollow Cathodes
Sammanfattning : Development of coating deposition technologies, in terms of performance and costs, is an ongoing process. A promising class of deposition technologies are based on hollow cathode discharges. LÄS MER
4. Measurements of High-Precision Atomic Data with Applications to Astrophysics and Cosmology
Sammanfattning : Investigations of astrophysical spectra require accurate atomic data, such as wavelengths and transition probabilities. This thesis provides high-precision atomic data for astrophysical and cosmological applications. The measurements have been carried out using Fourier transform spectrometry on light produced in a hollow cathode light source. LÄS MER
5. Development of Experimental Methods, Data Analysis and Standards in Atomic Spectroscopy
Sammanfattning : The focus of this work is on the experimental techniques and data analysis in atomic spectroscopy. Improved methods for the analysis of spectra and the determination of level energies are presented. Most of these are based on a rigorous statistical treatment of the spectroscopic data. LÄS MER
