• Fabrication and characterisation of a miniature Helium-4 evaporation pot made from single crystal silicon 

  Agar, David (2002)

• Minimum detection limits and applications of proton and helium induced X-ray emission using transition-edge sensor array 

  Käyhkö, Marko; Palosaari, M. R. J.; Laitinen, Mikko; Arstila, Kai; Maasilta, Ilari; Fowler, J. W.; Doriese, W. B.; Ullom, J. N.; Sajavaara, Timo (Elsevier B.V., 2017)

  We have determined minimum detection limits, MDLs, for elements 14 ≤ Z ≤ 86 using a transition-edge sensor array, TES array, and as a comparison using an Amptek X-123SDD silicon drift detector, SDD. This was done using ...

• Imaging Bacterial Colonies and Phage-Bacterium Interaction at Sub-Nanometer Resolution Using Helium-Ion Microscopy 

  Leppänen, Miika; Sundberg, Lotta-Riina; Laanto, Elina; De Freitas Almeida, Gabriel; Papponen, Petri; Maasilta, Ilari (Wiley, 2017)

  Imaging of microbial interactions has so far been based on well‐established electron microscopy methods. This study presents a new way to study bacterial colonies and interactions between bacteria and their viruses, ...

• Observation of a superfluid component within solid helium 

  Lauter, Hans; Apaja, Vesa; Kalinin, I.; Kats, E.; Koza, M.; Krotscheck, E.; Lauter, V.V.; Puchkov, A.V. (American Physical Society, 2011)

  We demonstrate by neutron scattering that a localized superfluid component exists at high pressures within solid helium in aerogel. Its existence is deduced from the observation of two sharp phonon-roton spectra which ...

• Direct writing of Josephson junctions in superconducting nitrides with focused helium ion beam 

  Ruhtinas, Aki (2020)

  Vuonna 2015 Cybart et al. osoittivat että Josephsonin liitoksia voi tehdä kuvioimalla suoraan heliumionisuihkulla YBCO ohutkalvoja. Tämä menetelmä on hyvin lupaava, sillä se voisi mahdollistaa Josephsonin liitosten ...
