  1. 6. Advanced X-ray Detectors for Industrial and Environmental Applications

    Författare :Salim Reza; Christer Fröjdh; Börje Norlin; Heinz Graafsma; Fulvia Arfelli; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering;

    Sammanfattning : The new generation of X-ray free electron laser sources arecapable of producing light beams with billion times higherpeak brilliance than that of the best conventional X-ray sources.This advancement motivates the scientific community to pushforward the detector technology to its limit, in order to de-sign photon detectors which can cope with the extreme fluxgenerated by the free electron laser sources.

  3. 7. Architecture and circuit design of photon counting readout for X-ray imaging sensors

    Författare :Suliman A Abdalla; Bengt Oelmann; Kenway Smith; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Sammanfattning : Hybrid pixel array detectors for X-ray imaging are based on different technologies for sensor and readout electronics. The readout electronics are based on standard CMOS technologies that are experiencing continuously rapid improvements by means of down-scaling the feature sizes, which in turn lead to higher transistor densities, lower power consumption, and faster circuits.

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

    Författare :Jonas Andersson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : 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. LÄS MER

  5. 9. Modeling the Performance of a Hybrid Pixel Detector for Digital X-ray Imaging

    Författare :Lilián del Risco Norrlid; Kjell Fransson; Massimo Caccia; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; Hybrid pixel detector; X-ray imaging; simulations; cascaded linear-systems; Strålningsvetenskap; Radiation biology; Strålningsbiologi;

    Sammanfattning : The development of digital detectors for X-ray imaging in medical diagnostics receives an increasing amount of attention. The detector under development at the Department of Radiation Sciences at Uppsala University is a hybrid pixel detector, which consists of a semiconductor sensor mounted onto a readout chip. LÄS MER

  7. 10. Capacity allocation mechanisms for grid environments

    Författare :Peter Gardfjäll; Erik Elmroth; Bo Kågström; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Grid computing; capacity allocation; allocation enforcement; accounting; Grid-wide fairshare scheduling; Web services; Computer science; Datavetenskap;

    Sammanfattning : During the past decade, Grid computing has gained popularity as a means to build powerful computing infrastructures by aggregating distributed computing capacity. Grid technology allows computing resources that belong to different organizations to be integrated into a single unified system image – a Grid. LÄS MER
