21. On the usage of a photon counting CT detector for SPECT
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : This work explores the possibility of using a photon counting silicon detector developedfor Computer Tomography (CT) in Single Photon Emission Computed Tomography(SPECT) applications. This would allow for a more versatile and a much cheapersystem. The main focus is on determining the efficiency and resolution of such a system. LÄS MER
22. Design, Construction and Characterization of a Portable Fast-Neutron Detector
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/KärnfysikSammanfattning : At European Spallation Source ERIC, 2 GeV proton bunches will be accelerated towards a tungsten target where spallation will occur, producing a wide neutron energy spectrum. Despite the shielding and moderators in place to stop and/or reduce their energy, a significant portion of the most energetic neutrons, called prompt neutrons, might still reach the sample position of a neutron-scattering instrument.

23. Monte Carlo simulation of the spatial response function of a SPECT measurement device for nuclear fuel bundles
M1-uppsats, Stockholms universitet/FysikumSammanfattning : The PGET device is currently being developed for partial-defect verication purposes on nuclear fuel assemblies. It Comprises CdTe detector elements in a heavy tungsten-alloy collimator, for which collimator slit openings define the field-of-view. LÄS MER
24. The Channeling Effect in Ultra-Thin dE-E Monolithic Silicon Telescopes
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/KärnfysikSammanfattning : A new method has been proposed to study the low energy resonances of 8Li(alpha,n)11B at Ecm ≅ 0.5 MeV using dE-E Monolithic Silicon Telescopes (MSTs). Each telescope consists of five ultra-thin ∼1 µm (dE) silicon detector pads on a ∼500 µm (E) silicon detector. LÄS MER
25. Development and study of luminescent bolometers for neutrino physics
Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)Sammanfattning : This Master thesis aims at designing, assembling and operating a prototypal luminescentbolometer containing a candidate with high Q-value (116Cd and 100Mo)for the study of the neutrinoless double- decay. The crystal is scintillating (with 116CdWO4 and Li2MoO4 compounds). LÄS MER
