Publikováno v: Hyperfine interactions 241(1), 25 (2020). doi:10.1007/s10751-019-1688-2

Ions of the isomer $^{229m}$Th are a topic of high interest for the construction of a "nuclear clock" and in the field of fundamental physics for testing symmetries of nature. They can be efficiently captured in Paul traps which are ideal for perform

Production, isolation and characterization of radiochemically pure 163Ho samples for the ECHo-project

Publikováno v: Radiochim.Acta
Radiochim.Acta, 2018, 106 (7), pp.535-547. ⟨10.1515/ract-2017-2877⟩

Several experiments on the study of the electron neutrino mass are based on high-statistics measurements of the energy spectrum following electron capture of the radionuclide 163Ho. They rely on the availability of large, radiochemically pure samples

Automatisierte Herstellung von gewickelten Formspulen

Autor: Jörg Franke, Raphael Haas, Benjamin Bickel

Publikováno v: Zeitschrift für wirtschaftlichen Fabrikbetrieb. 112:584-587

Kurzfassung Die adaptive Formspulenwicklung bietet das Potenzial, dem wachsenden Bedarf an elektrischen Tranktionsantrieben mit höchster Leis-tungsdichte und Effizienz gerecht zu werden. Für die Herstellung der Spulen wurde eine Wickelanlage zur fl

Hyperfine Interactions

$^{229}$Th is the only nucleus currently under investigation for the development of a nuclear optical clock (NOC) of ultra-high accuracy. The insufficient knowledge of the first nuclear excitation energy of $^{229}$Th has so far hindered direct nucle

Publikováno v: Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms. 376:388-392

The determination of the electron neutrino mass by calorimetric measurement of the 163 Ho electron capture spectrum requires ultra-pure samples. Several collaborations, like ECHo or HOLMES, intend to employ microcalorimeters into which 163 Ho is impl
