  1. 26. Computational simulations of the Axion Longitudinal Plasma HAloscope

    University essay from Stockholms universitet/Fysikum

    Author : Tove Klaesson; [2022]
    Keywords : ;

    Abstract : The quantum chromodynamics axion is a very light hypothetical particle that may simultaneously solve the dark matter and the strong CP problem. Recently, a new type of haloscope that can detect the resonant conversion of axions to photons was suggested, The Axion Longitudinal Plasma HAloscope (ALPHA). READ MORE

  3. 27. PERFORMANCE OF THE PHOTODETECTOR FOR THE ACTIVE SHIELD OF THE COSI SPACE TELESCOPE

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Daniel Álvarez Franco; [2022]
    Keywords : Geant4; scintillation; BGO; CsI; simulation; COSI; telescope; photoelectric effect;

    Abstract : The COmpton Spectrometer and Imager (COSI) is a space telescope that aims to study the soft gamma regime (0.2-5 MeV), capable of performing spectroscopy, imaging and polarimetry of cosmic gamma sources. READ MORE

  4. 28. Multi-spectral X-ray imaging with a laser-plasma accelerator

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

    Author : Andrea Angella; [2022]
    Keywords : Multi-spectral imaging; single-photon counting; X-ray absorption spectroscopy; XAS; LWFA; laser-wakefield acceleration; K-edge; imaging; metal-detection algorithm; Physics and Astronomy;

    Abstract : This master thesis focuses on the creation of an algorithm to perform multispectral imaging of a metallic target using X-rays. The generation of an ultrashort high-power low-divergent X-ray beam is performed by means of a Ti:Sapphire laser driven wake-field plasma accelerator. READ MORE

  5. 29. Sharing Quantum Resources Across a Metropolitan Network

    University essay from KTH/Tillämpad fysik

    Author : Martin Carlnäs; [2022]
    Keywords : QKD; Entanglement; SNSPD; Quantum Dot; Exciton; Biexciton; QKD; Kvantsammanflätning; SNSPD; Kvant Prick; Exciton; Biexciton;

    Abstract : Kvantsammanflätning har varit ett populärt ämne bland fysiker i snart 100 år då det tydligt belyser hur annorlunda kvantmekanikens värld är jämfört med den klassiska verklighet vi lever i. Med tiden har kvantsammanflätning blivit mer och mer välförstått och teknologier ämnade att utnyttja det har de senaste årtionden kommit allt närmare till industriell använding. READ MORE

  6. 30. 3′-end fluorescence labelling of long RNAs using terminal deoxynucleotidyl transferase

    University essay from Lunds universitet/Kemiska institutionen

    Author : Johannes Lidberg; [2022]
    Keywords : Physical biochemistry; Fluorescence; In vitro transcription; RNA; Terminal deoxynucleotidyl transferase; Nucleobase analogue; Chemistry;

    Abstract : Through recent years, RNA has rapidly gone from mainly being known as a passive information-carrying molecule within the central dogma of molecular biology to becoming the active ingredient in multiple therapeutics, such as in vaccines and potential drugs against cancer. However, one of the main challenges with RNA as a therapeutic is efficient delivery to cells. READ MORE
