(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)We study cosmic-ray-atmosphere collisions as a permanent production source of exotic millicharged particles (MCPs) for all terrestrial experiments. [MCPs are also known as charged massive particles (CHAMPs).] Based on data ...

A new dosimetric protocol for high energy photon radiotherapy beams in Norway using radiochromic filmRestricted Access (Master thesis / Masteroppgave, 2008)The continual development of high energy photon beam radiotherapy in Norway urges for a revision in dosimetric quality controls. It is favorable to use sharply defined fields, but existing routines for quality assurance ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The Cu-Pd-Sn material system has a (Cu, Pd) 3 Sn phase region that shows an interesting and unexplored marten- sitic phase transformation. Literature on this system is limited and the description of the phases present is ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Plasmonically active nanoparticles offer a promising pathway to extend the absorption range of photocatalysts. While not necessarily catalytically active themselves, these particles allow the absorption of lower energy ...
