The Resonance Ionization Laser Ion Source (RILIS) is the principal ionization technique for radioactive ion beam production at the CERN-ISOLDE on-line isotope separator facility. We introduce the photoionization spectroscopy apparatus (PISA), a compact atomic beam unit for RILIS ionization scheme development. Samples of the element to be investigated can be evaporated from an oven and ionized using the RILIS lasers. Other additional applications of PISA are envisaged: During setup it provides the means to optimize some laser parameters prior to the availability of an ion beam from the target; During operation it could serve as an additional observable for the RILIS performance monitoring; PISA can be used as a reference while performing in-source laser spectroscopy.
We will present the current status of integration into the RILIS setup and results from first applications of PISA to scheme development and in-source laser spectroscopy. We conclude with an outlook on future upgrades of PISA towards mass selectivity and faster sample switching.
