Description
The JYFL Accelerator Laboratory (JYFL-ACCLAB) is one of the leading stable beam facilities in Europe, conducting world class research on basic natural phenomena. Presently the laboratory hosts four accelerators with a variety of ion sources and innovative instrumentation for fundamental research, ion-beam based materials physics and applications. The current main research facilities includes the on-line isotope separator IGISOL producing low-energy radioactive ion beams (RIBs) which are coupled to ion/atom traps and laser systems, two recoil separators (gas-filled, RITU, and vacuum mode, MARA) with novel multi-detector systems for low cross-section in-beam and stopped-beam spectroscopy experiments, infrastructure for a variety of ion beam analysis methods and a RADiation Effects Facility, RADEF.
The IGISOL facility explores ground- and isomeric state properties of nuclei via mass spectrometry as well as laser and decay spectroscopy for nuclear structure and astrophysics, and fundamental interactions. Recent developments include combining laser resonance ionization with sensitive mass separation and detection resulting in almost background free measurements at the N = Z line. New international projects MORA and SEASON are under commissioning or data taking. Future programs include novel laser- and sympathetic cooling techniques for ultra-high precision measurements, coupling the MR-TOF mass spectrometer for collinear laser spectroscopy as well as a decay spectroscopy station.
The nuclear spectroscopy team, with state-of-the-art detector systems coupled with recoil separators, have produced a wealth of in-beam and decay studies, probing structures and phenomena in proton drip-line nuclei and heavy elements produced via heavy-ion fusion-evaporation reactions. The JUROGAM3 array of Ge detectors can be moved with ease between the target positions of both separators, and ongoing developments towards realizing a gas cell at the focal plane of MARA to deliver exotic beams to a new low-energy branch continues.
In this presentation I will present an overview of the status of the facility and will highlight the current research activities as well as new projects underway and soon to be realized. I will also endeavor to show the important complementarity with the ISOLDE facility, through our joint physics programs and infrastructure development.
