FP7 Unione Europea

University of Jyväskylä

The University of Jyväskylä with its 7 faculties is one of the largest universities in Finland. The Department of Physics (JYFL) belongs to the Faculty of Mathematics and Science.

Its research covers theoretical and experimental subatomic and material physics and their applications.

The JYFL Accelerator Laboratory (http://www.jyu.fi/accelerator) is part of the Department of Physics. The laboratory consists of a modern cyclotron (since 1995), which is capable to accelerate large variety of light and heavy ions. The use of the cyclotron provides beam time of around 7000 hours a year. In a short time the laboratory has grown to be one of the leading accelerator facilities in Europe. Its status is recognized in the Long Range Plan of NuPECC (ESF expert committee). It is also an official test site of space electronics of European Space Agency, ESA, and one of the access infrastructures in the EU-FP6-I3 –EURONS project. It has also the status of the Centre of Excellences of the Academy of Finland for the years 2006-2017.

The increased demands for radiation testing in Europe attracted ESA to the JYFL-Accelerator Laboratory. In 2004 an ESTEC/Contract No. 18197/04/NL/CP between ESA and JYFL was signed:”Utilisation of the High Energy Heavy Ion Test Facility for Component Radiation Studies”. The upgrade of the station was completed for the acceptance test campaign in April 2005. In the inauguration, held along with the RADECS Thematic meeting on European SEE Accelerators in May 2005, laboratory’s RADiation Effects Facility, RADEF, was qualified to one of ESA’s External European Component Irradiation Facilities (ECIF).

RADEF includes heavy-ion and proton beam lines for irradiation of space electronics. It consists of vacuum chamber and equipment for beam quality and intensity analysis. A special beam cocktail and user interface for monitoring flux and fluence was developed. RADEF provides both heavy ions and protons in the same facility. Its other specialty is the high penetration ion cocktail, developed during the upgrade, with the maximum energy of 1.22 GeV for xenon.

 

 

Dr. Ari Virtanen is the Research Director in the Accelerator Laboratory of the University of Jyväskylä. He received his Ph.D. in nuclear structure physics in January 1990.

Dr. Virtanen was promoted to Docent in 1995 and during the same year he was as a project manager in Jyväskylä Science Park Ltd. Since 1996 he has managed Nuclear— and Accelerator Application program started in the Accelerator Laboratory. Since that about 30 industry related projects have been performed under his guidance. The three most important on-going commercial projects are the radioisotope production for a Finnish medical company, the final product being used in biggest hospitals in Finland, radiation tolerance tests for ESA and European space industry and the production of porous membranes for a Swiss-German company. In addition to these his research activities include applications for radiation— and accelerator physics, radiotherapy and related R&D projects, neutron generator physics and developing of radiographic methods for Finnish energy and paper industry.

He heads his own research group in the Accelerator Laboratory. The group operates a heavy ion radiation effects facility, RADEF, which has been used by several European companies and NASA. Dr. Virtanen is a member of IEEE and belongs to the council of the European Radiation Effects Association, RADECS. He has been invited speaker, reviewer, session chair and scientific and awarding committee member in several international conferences, like NSREC, RADECS and RASEDA. Dr. Virtanen organized and was the general chair of the 8th international RADECS workshop, held in Jyväskylä, September 2008. He has been founding three companies in Finland and has acted as a chairman and member in their boards as well as in many steering groups for National Technology Agency and Technical Research Centre of Finland, Renewable Energy Programme of the University of Jyväskylä and has held a chair of Accelerator Physics Division of the Finnish Physical Society.
