Karin Fisher

During her studies, Karin Fisher researched the heating and cooling of ions in a linear Paul trap, specifically how the control of the trap confinement affects the motional state of the trapped ions.  Karin further investigated how the control of the trap confinement can be applied to rovibrational spectroscopy of molecular ions, specifically MgH+. The techniques developed during her studies will be used to improve the resolution of rovibrational spectroscopy of MgH+ by several orders of magnitude, and can be further applied to studies of cold chemistry and cold collisions.

The PhD degree was completed at the Department of Physics and Astronomy, Science and Technology, Aarhus University.

This résumé was prepared by the PhD student.
