Oral presentation from Dr. Manfred on Workshop on Plasma Spectroscopy in Oxford

Dr. Manfred also presented at the 8th International Workshop on Plasma Spectroscopy in Oxford, UK. She gave an oral presentation on cavity ring-down Faraday rotation spectroscopy (CRD-FRS), a technique with close ties to cavity-based polarimetry. The technique is useful for selectively measuring paramagnetic species, such as the HO2 radical, since only molecules with a non-zero magnetic moment will exhibit the Faraday effect, causing a rotation in the polarization of intracavity light in the presence of an external magnetic field. A high sensitivity is achieved using a high finesse optical cavity. Dr. Manfred’s conference paper included HO2 measurements by a previous postdoctoral research as well as her new work on Verdet constants.
