  1. 1. Material decomposition using a photon counting X-ray detector in low energy range

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Rasmus Solem; [2021]
    Keywords : Medicine and Health Sciences;

    Abstract : Material decomposition in X-ray imaging is used to separate different materials or elements in an image and to quantify their respective concentration. The material decomposition and quantification are made possible by the dependency of attenuation on the attenuating material and photon energy. READ MORE

  3. 2. Development of an absorption model for gas discharge lamp simulation

    University essay from Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)

    Author : Oscar Vigstrand; [2021]
    Keywords : Discharge lamp; Plasma; UV radiation;

    Abstract : Ultraviolet (UV) light has been used for disinfection purposes for over 100 years. Irradiation by UV light is a method to disinfect surfaces in order to prevent microbiological growth. At Tetra Pak this is of great importance as they are manufacturer of filling machines. READ MORE

  4. 3. Generating quantum entangled photons

    University essay from KTH/Skolan för teknikvetenskap (SCI); KTH/Skolan för teknikvetenskap (SCI)

    Author : Stephan Nieto; Daniel Sanaee; [2021]
    Keywords : ;

    Abstract : In this project a laser setup was constructed, quantum entangled photons were generated and two different methods were used to show said entanglement. The entangled photons were generated through a process called spontaneous parametric down conversion (SPDC). READ MORE

  5. 4. Optimization of e-beam and x-ray target geometry of a solid x-ray anode source

    University essay from Uppsala universitet/Materialfysik

    Author : Giacomo Luani; [2021]
    Keywords : ;

    Abstract : The X-ray tube is one of the most common types of X-ray sources, which is widely used in research laboratories and industry. Electrons are accelerated towards a metallic target to generate X-ray photons, thus creating a significant thermal load on the metal. READ MORE

  6. 5. The sensitivity of the EMC algorithm to the light intensity and amount of diffraction patterns in diffraction experiments

    University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Molekylär biofysik

    Author : Johanna Rogvall; [2021]
    Keywords : Diffraction; EMC; coherent diffraction imaging; Condor; XFEL;

    Abstract : To understand the function of macromolecules like proteins it helps to know the structure of the molecule. Coherent diffraction imaging is an emerging method that might be used to figure out the structures of macromolecules. READ MORE
