Abstract The Collinear Resonance Ionization Spectroscopy (CRIS) experiment, located at the ISOLDE facility, has recently performed high-resolution laser spectroscopy, with linewidths down to 20 MHz. In this article, we present the modifications to the beam line and the newly-installed laser systems that have made sensitive, high-resolution measurements possible. Highlights of recent experimental campaigns are presented. Keywords CRIS · ISOLDE · Laser spectroscopy · Resonance ionization
1 Introduction The Collinear Resonance Ionization Spectroscopy (CRIS) experiment combines the two standard techniques of laser spectroscopy. The collinear geometry of fast-beam laser spectroscopy, allowing high resolution measurements, is combined with the high-detection efficiency of the resonance-ionization technique. With the CRIS experiment located at the radioactive beam facility ISOLDE, this provides the ability to perform highly-sensitive laser spectroscopy measurements on exotic isotopes.
