description | Several particle detector technologies were studied. These include measurements of the leakage current and capacitance of irradiated planar and 3D sensors. The inter-electrode capacitance of proton irradiated 3D sensors was measured using two methods and compared to simulation. Planar n-type MCz diodes were exposed to neutron and gamma radiation and the effects on defects characterized. A set of n- and p-type Fz and MCz diodes were irradiated with protons and their annealing properties extracted using the Hamburg Model. A measurement of the fraction of D^{*+} mesons originating from a b-quark compared to those directly produced from a charm is presented. The charm mesons were fully reconstructed in the mode D^{*+} -> D^{0}pi^{+} where D^{0} -> K^{-}pi^{+}. The analysis was based on data collected from the minimum bias trigger of the ATLAS detector at sqrt{s}=7 TeV proton-proton collisions produced by the LHC. The distribution of the impact parameter of the D^{0} meson with respect to the primary vertex was studied to distinguish charm mesons produced promptly from those through b-quark decays. |
