1. 1. Structural analysis of HZO thin film and electrode using X-ray diffraction

   Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Författare :Elliot Winsnes; [2024]
   Nyckelord :HZO; hafnia; hafnium dioxide; zirconium dioxide; ferroelectricity; ferroelectric; synchrotron radiation; X-ray diffraction; Physics and Astronomy;

   Sammanfattning : Since its discovery in 2011, the ferroelectricity of thin films based on HfO2 has been studied intensively. In particular, thin films with a 1:1 ratio of HfO2 and ZrO2 (HZO) has been of great interest. The ferroelectricity arises from a non-centrosymmetric orthorhombic (o) phase of HZO whose prevalence is dependent on the processing conditions. LÄS MER

3. 2. Analysis of Atmospheric Muon Bundles with IceCube

   Master-uppsats, Uppsala universitet/Högenergifysik

   Författare :Anna Selina Neyer; [2024]
   Nyckelord :;

   Sammanfattning : This work is a preliminary study of the background of a search for dark, long-lived particles in the IceCube detector. The high flux of atmospheric muons in IceCube is considered background to the detector's primary science goal, which is to detect astrophysical neutrinos through the emission of Cherenkov radiation.

4. 3. Development of Radon Detectors for Earthquake Prediction

   Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

   Författare :Alma Partos; Astrid Schöldström; [2023]
   Nyckelord :Radon; earthquake; gamma ray spectroscopy;

   Sammanfattning : The purpose of this project is to simulate the detection of γ-ray spectra emitted by radon isotopes and their daughters. This is done as a contribution to the development of radiation detectors to be used in a research project investigating the possibility of using increased amounts of the radioactive gas radon as an earthquake precursor.

5. 4. The Commissioning of a Pixelated Charge-particle Detector : for High-sensitivity Measurements of Hydrogen

   Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysik

   Författare :Joacim Stenlund; Aram Himelius; [2023]
   Nyckelord :;

   Sammanfattning : The Tandem Laboratory at Uppsala University, a national research infrastructure forworld-leading materials analysis, has a long history of performing hydrogen measurementusing NRA (Nuclear Reaction Analysis). This project intents to diversify the infras-tructure for hydrogen measurement by investigating the feasibility of an advanced ERCS(Elastic Recoil Coincidence Scattering) system, enabling finer detection limits.

7. 5. Evaluation of hardware and firmware for a Data Readout system of the PANDA Electro-Magnetic Calorimeter

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Ehsan Noorzaei; [2023]
   Nyckelord :;

   Sammanfattning : PANDA is the next generation hadron physics detector under construction at the Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany to accurately detect and parameterize events with kinetic energies from 1MeV to 8GeV. PANDA is a 4π detector and due to its unique shape, all the readout electronics from ADC modules, power supplies, and a controller unit is housed in liquid-cooled crates mounted inside the detector.
