  2. 11. The Penning trap mass spectrometer SMILETRAP II and evaporative cooling of highly-charged ions

    Author : Matthias Hobein; Reinhold Schuch; David Lunney; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Penning trap; Precision mass spectrometry; Atomic mass; Highly-charged ions; Evaporative cooling; Coherent oscillation; Ion beam emittance; Atomic physics; Atomfysik; fysik; Physics;

    Abstract : Accurate mass values have wide-ranging applications in physics and metrology, allowing, for example, to test quantum electrodynamics and fundamental symmetries, to determine fundamental constants, and to establish weight standards. This thesis describes the new high-precision double-Penning trap mass spectrometer SMILETRAP II which aims at relative uncertainties in the mass determination of 10-10 and below. READ MORE

  6. 14. New atomic masses related to fundamental physics measured with SMILETRAP

    Author : Szilárd Nagy; Reinhold Schuch; Gunter Werth; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Penning Trap; mass spectrometry; Atomic physics; Atomfysik;

    Abstract : This thesis describes the recent improvements of the SMILETRAP Penning trap mass spectrometer and a number of interesting high precision mass measurements, which have been performed using the improved apparatus, and are relevant in todays fundamental physics problems. The mass of the hydrogen-like 24,26Mg ions as well as the masses of the hydrogen- and lithium-like 40Ca ions are presented in this work that are indispensable input values when evaluating g-factor measurements of the bound electron.
