Low-energy electron ionization mass spectrometer for efficient detection of low mass species
Bergin, Matthew; Ward, David J.; Lambrick, Sam; von Jeinsen, N. A.; Holst, Bodil; Ellis, John; Jardine, Andrew P.; Allison, William (Journal article; Peer reviewed, 2021)The design of a high-efficiency mass spectrometer is described, aimed at residual gas detection of low mass species using low-energy electron impact, with particular applications in helium atom microscopy and atomic or ... -
Material properties particularly suited to be measured with helium scattering: selected examples from 2D materials, van der Waals heterostructures, glassy materials, catalytic substrates, topological insulators and superconducting radio frequency materials
Holst, Bodil; Alexandrowicz, Gil; Avidor, Nadav; Benedek, Giorgio; Bracco, Gianangelo; Ernst, Wolfgang E.; Farias, Daniel; Jardine, Andrew P.; Lefmann, Kim; Manson, Joseph R.; Marquardt, Roberto; Artés, Salvador Miret; Sibener, Steven J.; Wells, Justin W; Tamtögl, Anton; Allison, William (Journal article; Peer reviewed, 2021)Helium Atom Scattering (HAS) and Helium Spin-Echo scattering (HeSE), together helium scattering, are well established, but non-commercial surface science techniques. They are characterised by the beam inertness and very ...
