Photo-Resonance Excitation and Cavity Ionization Spectroscopy Apparatus  

The primary goal of this project is the development of a novel laser spectroscopy experiment which will provide experimental access to the electromagnetic properties of key light nuclear systems that are currently out of reach for state-of-the-art methods. This new apparatus is expected to achieve an unprecedented combination of sensitivity and precision for the study of short-lived nuclei in different unexplored regions of the nuclear chart.

This experimental apparatus requires the integration of technological developments from three different fields: i) laser spectroscopy of exotic isotopes, ii) quantum optics (large-mode high-finesse optical cavities) and iii) photoelectron spectroscopy (electron detector). A simplified scheme (not to scale) is shown in the figure below.



This novel technique, which builds on the techniques that we have developed at CERN [1-4], offers a high degree of versatility and compactness, allowing it to be applied at different facilities worldwide such as FRIB (US), CERN (Switzerland), TRIUMF (Canada), GANIL-SPIRAL2 (France), GSI-FAIR (Germany) and Jyväskylä (Finland). Applications in other fields such as atomic and molecular spectroscopy, as well as applied research, are envisaged.
