Brief description of the accelerator infrastr:

The accelerator facility at JYFL consisting of a K=130 cyclotron with two ECR and a multi-cusp ion sources delivers one of the largest variety of stable-ion beams suitable for nuclear physics research and applications in Europe. Its reliability is reflected in the annual operation time, which during the last years has been close to 7000 hours. As a university laboratory attached to the Department of Physics it also forms an ideal training site for PhD students and young researchers.

At the JYFL accelerator laboratory, access can be offered also to the new 1.5MV Pelletron accelerator.

A new K=35 light-ion cyclotron will be commissioned in 2009 at JYFL. Consequently, more beam time will be available for the users and for the development of high-intensity heavy-ion beams as well as various tests needed in the development of new instrumentation.

Major instrumentation The main experimental facilities available for the users are the RITU recoil separator with detector arrays at the target (JUROGAM Ge detector array) and the focal plane (GREAT spectrometer) and the IGISOL separator with ion traps and laser spectroscopy systems. The former uses heavy ions and is at the moment the most efficient system in the world for tagging experiments of heavy exotic nuclei. The latter mainly uses high-intensity proton beams to produce various species of cooled and bunched radioactive ion beams via fission for studies of ground-state and decay properties of exotic nuclei. Beam lines and instrumentation for nuclear reaction studies are also available. Special beam lines have been designed for various applications and test experiments.
