Sammanfattning : Synchrotron radiation laboratories are large scientific facilities where various scientific experiments are carried out by the use of radiation produced by particle accelerators. Research with synchrotron radiation emerged in the 1960s and 1970s as a peripheral activity at particle physics laboratories. LÄS MER
Sammanfattning : Synchrotron radiation sources have greatly contributed to the progress in many fields of science. The development of the storage ring technologies has made possible to obtain very low emittance electron beams, which together with the use of undulators allow guiding a very high photon flux into a very small spot required by the experiments.

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
Sammanfattning : This thesis summarises experimental results on the molecular spectroscopy of gas phase molecules excited by synchrotron radiation in the VUV and soft X-ray regions. We have used three diﬀerent detection techniques, photon induced ﬂuorescence spectroscopy, photoionisation mass spectroscopy and near edge X-ray absorption ﬁne structure spectroscopy to study molecular deuterium, hydrogen sulphide, ammonia, methanol, pyridine, pyridazine, pyrimidine, pyrazine, s-triazine, and 2-deoxy-D-ribose, the last one also known as the DNA sugar.
