Ultra-Sensitive Collinear Fast Ion Beam Trace Detection of Kr Conference Paper uri icon

abstract

  • A novel scheme of collinear fast beam laser spectroscopy for the detection of the long lived rare isotope 85Kr by observing the optical hyperfine structure spectrum is presented. The technique utilizes cascade two-step excitation to pump metastable krypton atoms to a high-lying Rydberg level. The present work on krypton was motivated by the fact that 85 Kr is a major tracer gas for exploring the reservoir structure of large oil fields. 85Kr detection in ambient air is also of importance for monitoring nuclear activities on a world wide scale. The technique has been successfully applied to stable krypton isotopes and to 85Kr. The selectivity is at the one part in 10 10 level and the sensitivity at a few hundred ions/s. 2009 American Institute of Physics.
