Sympathetically cooled molecular ions: from principles to first applications
Bernhard Roth, Stephan Schiller
We review the current status of the field of sympathetically cooled molecular ions, i.e. the method used for cooling the translational degrees of freedom, the techniques applied fo…
Translational cooling and storage of protonated proteins in an ion trap at subkelvin temperatures
D. Offenberg, C. B. Zhang, Ch. Wellers +2
Gas-phase multiply charged proteins have been sympathetically cooled to translational temperatures below 1 K by Coulomb interaction with laser-cooled barium ions in a linear ion tr…
Measurement of small photodestruction rates of cold, charged biomolecules in an ion trap
D. Offenberg, Ch. Wellers, C. B. Zhang +2
In this work, we demonstrate measurements of photodestruction rates of translationally cold, charged biomolecules. The long-term stable storage of the molecular ions in an ion trap…
Precision Spectroscopy of Molecular Hydrogen Ions: Towards Frequency Metrology of Particle Masses
B. Roth, J. Koelemeij, S. Schiller +4
We describe the current status of high-precision ab initio calculations of the spectra of molecular hydrogen ions (H_2^+ and HD^+) and of two experiments for vibrational spectrosco…
Ellipsoidal Coulomb Crystals in a Linear Radiofrequency Trap
U. Fröhlich, B. Roth, S. Schiller
A static quadrupole potential breaks the cylindrical symmetry of the effective potential of a linear rf trap. For a one-component fluid plasma at low temperature, the resulting equ…
Sympathetic cooling of He ions in a radiofrequency trap
B. Roth, U. Fröhlich, S. Schiller
We have generated Coulomb crystals of ultracold He ions in a linear radiofrequency trap, by sympathetic cooling via laser--cooled Be. Stable crystals containing up…
