(Master thesis, 2009-11-20)
Oppgaven tar for seg mekaniske, elektriske og akustiske målinger i luft på piezoelektriske skiver av typen PZT-5A med et diameter/tykkelsesforhold på 7.5. Målingene blir sammenlignet med teoretiske modeller for skivenes ...
• Birkeland current effects on high-latitude ground magnetic field perturbations ﻿

(Peer reviewed; Journal article, 2015-09-18)
Magnetic perturbations on ground at high latitudes are directly associated only with the divergence-free component of the height-integrated horizontal ionospheric current, J⊥,df. Here we show how J⊥,df can be expressed as ...
• Blind-prediction: estimating the consequences of vented hydrogen deflagrations for inhomogeneous mixtures in 20-foot ISO containers ﻿

(Peer reviewed; Journal article, 2019-09)
This paper summarises the results from a blind-prediction benchmark study for models used for estimating the consequences of vented hydrogen deflagrations, as well as for users of such models. The work was part of the HySEA ...
• Breakdown of the nonrelativistic approximation in superintense laser-matter interactions ﻿

(Peer reviewed; Journal article, 2019)
We study the breakdown of the nonrelativistic approximation in the multiphoton ionization of atomic hydrogen by some intense x-ray laser pulse, in a regime where the dipole approximation is no longer valid. To this end, ...

(Master thesis, 2009-09-01)
The Large Hadron Collider (LHC) is under construction beneath the border between Switzerland and France. If it is successful, it will accelerate and collide protons at 7 T eV per proton in center of mass. Furthermore, it ...
