ALICE TPC Upgrade Activities for LHC Run 3 and Beyond: "SAMPA ASIC Tests with GEM Detector Prototype"
(Master thesis, 2015-09-11)The Time Projection Chamber (TPC) signal readout of the ALICE detector is being upgraded to accommodate the higher collision rates and -energies during LHC Run 3 in 2018. Due to the increased collision rates, the TPC drift ... -
The ALICE TPC, a large 3-dimensional tracking device with fast readout for ultra-high multiplicity events
(Peer reviewed; Journal article, 2010-10-01)The design, construction, and commissioning of the ALICE Time-Projection Chamber (TPC) is described. It is the main device for pattern recognition, tracking, and identification of charged particles in the ALICE experiment ... -
The ALICE Transition Radiation Detector: Construction, operation, and performance
(Peer reviewed; Journal article, 2018-02)The Transition Radiation Detector (TRD) was designed and built to enhance the capabilities of the ALICE detector at the Large Hadron Collider (LHC). While aimed at providing electron identification and triggering, the TRD ... -
Alignment of the ATLAS Inner Detector in Run 2
(Journal article; Peer reviewed, 2020-12-24)The performance of the ATLAS Inner Detector alignment has been studied using pp collision data at s√=13TeV collected by the ATLAS experiment during Run 2 (2015–2018) of the Large Hadron Collider (LHC). The goal of the ... -

Altering the wetting properties of FEP films by nano-structuring the surface using reactive ion etching
(Master thesis, 2017-10-18)Renewable energy sources has become a large field of research, and in the recent years, methods to harvest energy from rain drops have been developed. This technology is based on rain drops rolling or sliding on a polymer ... -
Alternative gauge for the description of the light-matter interaction in a relativistic framework
(Peer reviewed; Journal article, 2017-08)We present a generalized velocity gauge form of the relativistic laser-matter interaction. In comparison with the (equivalent) regular minimal coupling description, this form of light-matter interaction results in superior ... -
An altitude and distance correction to the initial fluence distribution of TGFs
(Peer reviewed; Journal article, 2014-10)The source fluence distribution of terrestrial gamma ray flashes (TGFs) has been extensively discussed in recent years, but few have considered how the TGF fluence distribution at the source, as estimated from satellite ... -
AME: A Cross-Scale Constellation of CubeSats to Explore Magnetic Reconnection in the Solar–Terrestrial Relation
(Journal article; Peer reviewed, 2020)A major subset of solar–terrestrial relations, responsible, in particular, for the driver of space weather phenomena, is the interaction between the Earth's magnetosphere and the solar wind. As one of the most important ... -
An Assessment of Extreme Mooring Loads for Floating Offshore Wind Structures Using Conditional Waves
(Master thesis, 2022-08-04)Wind power is one of the fastest-growing industries in the world and plays a significant role in the transition to sustainable energy systems. However, the costs of substructures and moorings limit the potential of floating ... -
“An Experimental Study of Bulk Foam Properties with Commercial Surfactants in Saline Environments”
(Master thesis, 2019-06-22)Foam is a fascinating two-phase phenomenon with a wide range of different industrial applications; contaminated-aquifer remediation, separation of waste-waters, enhanced oil recovery, gas leakage prevention and matrix-acidizing ... -

Analysis and Development of Phenomenological Models for the Relative Biological Effectiveness in Proton Therapy
(Doctoral thesis, 2019-08-23)Proton therapy is undergoing a rapid development making it increasingly popular as a treatment of cancer. Protons interact differently with the tissue compared to conventional radiation therapy with photons, resulting in ... -
Analysis of 3D Pixel Detectors for the ATLAS Inner Tracker Upgrade
(Master thesis, 2017-06-16)The silicon 3D pixel detector represent a detector technology that has a higher radiation tolerance compared to the conventional planar pixel detectors. This detector technology is one of the technologies proposed to be ... -
Analysis of a Costly Fiberglass-Polyester Air Filter Fire
(Journal article; Peer reviewed, 2022)In September 2020, a fire at a liquefied natural gas (LNG) plant in the Arctic areas of Norway received national attention. In an unengaged air intake, the heat exchanger designed to prevent ice damage during production ... -
Analysis of Blue Corona Discharges at the Top of Tropical Thunderstorm Clouds in Different Phases of Convection
(Journal article; Peer reviewed, 2022)We report on observations of corona discharges at the uppermost region of clouds characterized by emissions in a blue band of nitrogen molecules at 337 nm, with little activity in the red band of lightning leaders at 777.4 ... -
