1. Radiation tests of semiconductor detectors
Sammanfattning : This thesis investigates the response of Gallium Arsenide (GaAs) detectors to ionizing irradiation. Detectors based on π-υ junction formed by deep level centers doping. LÄS MER
2. Processing of semiconductor detectors for ionised particles and photon radiation
Sammanfattning : .... LÄS MER
3. First Principles Calculations of Electron Transport and Structural Damage by Intense Irradiation
Sammanfattning : First principle electronic structure theory is used to describe the effect of crystal binding on radiation detectors, electron transport properties, and structural damage induced by intense irradiation. A large database containing general electronic structure results to which data mining algorithms can be applied in the search for new functional materials, a case study is presented for scintillator detector materials.

4. Modeling the Performance of a Hybrid Pixel Detector for Digital X-ray Imaging
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
5. DIXI – a Hybrid Pixel Detector for X-ray Imaging
Sammanfattning : Medical X-ray imaging is an important tool in diagnostic radiology. The ionising-radiation dose to the patient is justified by the clinical benefit of the examination. Nonetheless, detectors that operate at even lower doses and provide more information to the radiologist are desired. LÄS MER
