Project Number: 262010
Duration: September 1, 2010 - September 1, 2014

Access Offered to External Research Groups:
The Accelerator Laboratory of the Department of Physics (JYFL) of the University of Jyväskylä (JYU) is one of the European Research Infrastructures within the European Nuclear Science and Applications Research (ENSAR) Integrated Infrastructure Initiative (I3) in EU-FP7. Thereby access is supported for eligible external research teams performing or planning experiments at JYFL. They can also apply for EC funding of their related travel and subsistence expenses. Proposals for experiments will be evaluated and selected on the basis of scientific merit through an independent peer review procedure. For research groups with accepted proposals, the research facilities including accelerators and experimental instrumentation are provided by JYFL free of any charges. Research teams eligible for supported access are those that conduct their research in the EC Member States (except Finland) or Associated States.

Description of the Facility:
Accelerator Facility: The main accelerator facility at JYFL consisting of a K=130 cyclotron with two ECR ion sources and a multi-cusp ion source delivers one of the largest varieties of stable ion beams (from p to Xe) suitable for modern nuclear physics research and applications. Recently the target hall was extended and equipped with an additonal new K=30 MeV light-ion cyclotron and associated beam lines. Commissioning of the system took place in 2009 and it will result in long and difficult experiments, as well as developmental work at both accelerators. A Pelletron accelerator (1.7 MV) is attached to the JYFL target hall and is available to users.

Main available instrumentation:
Nuclear Spectroscopy: The RITU gas-filled recoil separator with detector arrays at the target area (JUROGAM Ge detector array) and the focal plane (GREAT spectrometer) is the most efficient system in the world for tagging studies of proton rich and very heavy nuclei. A new SAGE spectrometer composed of JUROGAMII and a novel in-beam electron spectrometer will be available at the RITU target. A new vacuum mode recoil-separator MARA will enable studies of nuclei close to the N=Z line in 2012.

IGISOL: A large amount of beam time is available for comprehensive studies of nuclear ground and isomeric states, as well as exotic decay modes, at the IGISOL ion-guide facility. IGISOL delivers various species of cooled and bunched radioactive ion beams to beam lines equipped with state-of-the-art ion traps for accurate mass measurements, detector systems for exotic decay modes and laser spectroscopy and ionization systems for hyperfine structure and charge radii studies.

RADEF: There is a dedicated beam line, equipped with a RADiation Effects Facility (RADEF), for studies of single-event effects (SEE) in electronics. The RADEF facility is also available for various radiation hardness tests of materials, sensors and detectors with light ions and heavy-ion cocktail beams delivered by the K=130 cyclotron.

Two beam lines are available for nuclear reaction studies and test experiments. One line is equipped with a scattering chamber of 1.5 meters in diameter.

Pelletron:The Pelletron accelerator is equipped with beam lines for the modification and characterisation of materials and MeV ion beam lithography.

Environment:

The JYFL Accelerator Laboratory is attached to the Department of Physics of JYU. Services of all laboratories at the Department, including the new Nanoscience Centre are available to all users. The Accelerator Laboratory also has close contacts with nuclear structure theory groups (nuclear theory, FIDIPRO) and experts of experimental and theoretical high-energy and materials physics at the Department of Physics.

Procedure to Apply for Beam Time:
There are two calls for proposals per year. Deadlines are September 15 and March 15. Proposals should be sent in written form to the PAC Secretary Dr. Mikael Sandzelius, Accelerator Laboratory, Department of Physics, University of Jyväskylä, P.O.Box 35, FIN-40014 University of Jyväskylä, Finland. The spokespersons are encouraged to contact Dr. Mikael Sandzelius (mikael.sandzelius@jyu.fi) for more detailed information about available instrumentation. The list of authors should preferably comprise in-house physicists.

Program Advisory Committee: 4 in-house, 6 international members

Reporting: The spokesperson of an ENSAR-supported experiment must fill in the experimental summary report.

Accommodation and Transportation in Jyväskylä:
University guest rooms, guest apartments and hotels in Jyväskylä. There is one hotel within 200 m from the Laboratory which can be reserved for external users. The Laboratory is located in the uptown area of Jyväskylä. Jyväskylä has an airport, and daily flights connect the town via Helsinki to most European cities in a few hours. Nowadays a train connection to Tikkurila may offer a more convenient way to catch flights from Helsinki.
