Public Release: 

The most powerful ion source in the world is now in the JYFL-ACCLAB

University of Jyväskylä - Jyväskylän yliopisto

A new ion source known as HIISI has been developed in the Accelerator Laboratory of the University of Jyväskylä (JYFL-ACCLAB). It is the most powerful room-temperature ion source in the world at the moment. A new facility allows for much higher ion beam intensities and energies from our main cyclotron. It will be used in fundamental research and in testing components of space satellites.

"The solutions is a fantastic achievement for our world-class ion source group and the technical staff of the laboratory. It come as a result of basic experimental research and deeper understanding of the various physical processes going on in the ion source plasma", says the leader of the Accelerator Laboratory, Professor Paul Greenlees.

HIISI was taken in use in January.

"These are fantastic results that make RADEF a top-class facility for the space industry in Europe, for the test of new high-tech components which are increasingly used for space applications", says Veronique Ferlet-Cavrois, the Head of the Power Systems and Space Environments Division of the European Space Agency (ESA).


The development- and construction work of HIISI was been co-financed by the Academy of Finland (FIRI), the European Space Agency and the University of Jyväskylä.

The solutions, experience and technology gained through the HIISI will be transferred to university's international partners, such as at GSI-FAIR in Darmstadt. A copy of HIISI will be constructed for joint research projects.
