  2. 1. Fragmentation studies of small molecules using synchrotron radiation

    Author : Emilio Melero García; KTH; []
    Keywords : Coincidence; fragmentation;

    Abstract : This thesis presents experimental data on the fragmentationof gas phase sulfur hexafluoride (SF6) and deutheromethane(CD4) molecules after their interaction with synchrotronradiation in the energy range of 70-200 eV. The data wasobtained using coincidence spectroscopy between energy resolvedelectrons and ions (EREICO). READ MORE

  4. 2. Ultrafast dynamics of small quantum systems studied using electron-ion coincidence spectroscopy

    Author : Smita Ganguly; Synkrotronljusfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; coincidence spectroscopy; photodissociation dynamics; fragmentation reaction; MOLECULAR-BEAM; Cluster fission; Astrochemistry; Carbon dioxide CO2 ; ; Adamantane;

    Abstract : Studying how small quantum systems, like molecules and clusters, interact with X-rays is crucial to understanding the ultrafast processes that occur in nature on incredibly short timescales, ranging from femtoseconds to picoseconds. X-rays excite small quantum systems to unstable core hole states, leading to a cascade of phenomena, including Auger decay, nuclear rearrangement, and dissociation. READ MORE

  5. 3. Fast Digital Trigger Systems for Experiments in High Energy Physics

    Author : Pawel Marciniewski; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; trigger; discrimination; data acquisition; Fysik; Physics; Fysik;

    Abstract : The data acquisition in high energy physics experiments is typically started by a pulse from a fast coincidence-based trigger system. It is essential that such a system can identify an event in a shortest possible time and with as good selectivity as possible. READ MORE

  6. 4. Multi-electron processes in atoms and molecules - Experimental investigations by coincidence spectroscopy

    Author : Jonas Andersson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis presents studies on multi-electron processes in atoms and molecules initiated by single-photon absorption. The experimental techniques used for these studies rely on synchrotron radiation offered at large scale user facilities, and a magnetic bottle spectrometer. READ MORE

  7. 5. System Studies and Simulations of Distributed Photovoltaics in Sweden

    Author : Joakim Widén; Ewa Wäckelgård; Brian Norton; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photovoltaics; Solar energy; Distributed generation; Load modelling; Time-use data; Markov chain; Power flow; Power system; Engineering physics; Teknisk fysik; Teknisk fysik; Engineering Science;

    Abstract : Grid-connected photovoltaic (PV) capacity is increasing worldwide, mainly due to extensive subsidy schemes for renewable electricity generation. A majority of newly installed systems are distributed small-scale systems located in distribution grids, often at residential customers. READ MORE
