ISOLDE Seminar

From CRIS to Artemis: spinning out Laser spectroscopy

by Kieran Flanagan (University of Manchester (GB))

ISOLDE's visitor room

The Collinear resonance ionization spectroscopy (CRIS) technique has now been used at ISOLDE to study isotopes far from stability. The goal of the method is to enable measurements of isotopes previously inaccessible due to low production yields and contamination of isobars. This technique has applications beyond nuclear physics and can be combined with existing mass spectrometry tools such as gas chromatography (GC), isotope ratio mass spectrometry (IRMS) and inductively coupled mass spectrometry (ICP-MS) to efficiently remove interferences (isobars) which will enhance the mass abundance sensitivity by more than 3 orders of magnitude. By improving the limit of detection of these techniques beyond the part per trillion level it becomes possible to detect cosmogenic isotopes in environmental samples using a “table top” device. This talk will present progress towards a table top radiocarbon detection device and commercialization project at the University of Manchester.
