Detection of CO2 in N2 and H2O using photoacoustics
(Master thesis, 2013-06-03)Photoacoustic spectroscopy is a technique where absorbed modulated light is released as heat, causing thermal expansion which can be detected using an acoustic transducer. It can be used to determine the absorption spectra ... -
Detection of low energy antiproton annihilations in a segmented silicon detector
(Peer reviewed; Journal article, 2014-06)The goal of the AEḡIS experiment at the Antiproton Decelerator (AD) at CERN, is to measure directly the Earth’s gravitational acceleration on antimatter by measuring the free fall of a pulsed, cold antihydrogen beam. The ... -
Detection of terrestrial gamma-ray flashes with the AGILE/MCAL
(Peer reviewed; Journal article, 2019)AGILE is one of the satellites currently detecting terrestrial gamma-ray flashes (TGFs). In particular, the AGILE MiniCALorimeter detected more than 2000 events in 8 years activity, by exploiting a unique sub-millisecond ... -
Determination of jet calibration and energy resolution in proton–proton collisions at √s=8TeV using the ATLAS detector
(Journal article; Peer reviewed, 2020)The jet energy scale, jet energy resolution, and their systematic uncertainties are measured for jets reconstructed with the ATLAS detector in 2012 using proton–proton data produced at a centre-of-mass energy of 8 TeV with ... -
Determination of the event collision time with the ALICE detector at the LHC
(Peer reviewed; Journal article, 2017-02)Particle identification is an important feature of the ALICE detector at the LHC. In particular, for particle identification via the time-of-flight technique, the precise determination of the event collision time represents ... -
Determination of the minimum ignition energy (MIE) of premixed propane/air
(Master thesis, 2009-06-12)This Master thesis describes an experimental study aimed at determining the minimum ignition energy (MIE) of premixed propane/air mixtures. Two fundamentally different circuits have been employed for creating the sparks ... -
Determination of the parton distribution functions of the proton from ATLAS measurements of differential W± and Z boson production in association with jets
(Journal article; Peer reviewed, 2021)This article presents a new set of proton parton distribution functions, ATLASepWZVjet20, produced in an analysis at next-to-next-to-leading order in QCD. The new data sets considered are the measurements of W+ and W− boson ... -
Determining Latitudinal Extent of Energetic Electron Precipitation Using MEPED On-Board NOAA/POES
(Journal article; Peer reviewed, 2022)Energetic Electron Precipitation (EEP) from the plasma sheet and the radiation belts ionizes the polar lower thermosphere and mesosphere. EEP increases the production of NOx and HOx, which will catalytically destroy ozone, ... -
Determining the fibrillar orientation of bast fibres with polarized light microscopy: the modified Herzog test (red plate test) explained
