  1. 1. Misalignment effects on the physics performance of the inner tracker upgrade at the ALICE experiment

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Författare :Jesper Karlsson Gumprecht; [2024]
    Nyckelord :ALICE; ITS; ITS2; ITS3; O2; O2Physics; Distortion; Misalignment; Alignment; Realignment; Physics and Astronomy;

    Sammanfattning : This thesis deals with the physics performance of an approved inner tracker upgrade of the ALICE experiment involving a novel and ultra-thin silicon detector with a cylindrical geometry. During the thesis work, a method was developed in simulations to induce distortions to the detector’s geometry, and the resulting loss in physics performance was evaluated. LÄS MER

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

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad kärnfysik

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

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

    Nyckelord :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;

    Sammanfattning : 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
