1. 1. Implementation and characterization of Silicon detectors for studies on neutron-induced nuclear reactions

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Leo Lehtilä; [2019]
   Keywords : Silicon detector; Silicon telescope; Ultra-thin silicon detector; Energy resolution; Radioactive source; Am-241; Cf-252; Fission Fragments; Alpha Particles;

   Abstract : Energy resolution characteristics of silicon surface barrier detector signals amplified by different preamplifiers and spectroscopic amplifiers have been studied. The characterization has been done using alpha particles from an 241Am source and spontaneous fission fragments from two Cf sources. READ MORE

3. 2. Detailed analysis of the chemical composition of stars harboring Earth-like planets

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Lorena Acuña Aguirre; [2019]
   Keywords : Physics and Astronomy;

   Abstract : Context. The planet-metallicity correlation for gaseous giants is widely accepted through spectroscopic studies. However, whether a similar correlation exists for terrestrial planets is a debated subject. READ MORE

4. 3. Mapping the present-day chemical abundance structure of the Solar neighbourhood: O & Si

   University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Kristiina Verro; [2017]
   Keywords : astrophysics; stellar spectroscopy; abundance analysis; solar neighbourhood; massive stars; Galaxy; Physics and Astronomy;

   Abstract : Context. Large scale chemical abundance gradients in the Galactic disks, small-scale abundance structures, and the mean chemical abundance values in the Solar vicinity, are important constraints to Galactic chemo-dynamical formation and evolution models. READ MORE

5. 4. The Channeling Effect in Ultra-Thin dE-E Monolithic Silicon Telescopes

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

   Author : Fredrik Parnefjord Gustafsson; [2017]
   Keywords : dead-layer; Channelling; The Channeling effect; Plasma effect; Nucleosynthesis; Astrophysics; Ultra-thin silicon detectors; Inhomogenous Big Bang; MST; deadlayer; Pelletron; 8Li; cross-section; Kikuchi pattern; Physics and Astronomy;

   Abstract : 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. READ MORE

6. 5. Commissioning of the ΔE-E LYCCA detector array

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

   Author : Alexander Huusko; [2017]
   Keywords : Physics and Astronomy;

   Abstract : LYCCA (Lund York Cologne CAlorimeter) is a versatile detector system which provides partial and residual energy measurements together with particle tracking and identification. The detector system consists of several different types of detectors such as DSSSDs (Double-Sided Silicon Strip Detector) and CsI(Tl) detectors. READ MORE
