INDIANA UNIVERSITY CYCLOTRON FACILITY (lUCF) 

 Indiana University 



"Big Science" Descriptor : Nuclear physics 



Description of Facility/Instrument : The Indiana University Cyclotron 



Facility provides high quality beams of protons, deuterons, helium 

 Ions, and lithium Ions In energies up to 200 million electron 

 volts for nuclear physics research. lUCF has been operating as a 

 national users facility since the first beams available for research 

 in the spring of 1976. The current demand is running at a rate 

 about three times that available (5000 hours per year). Comprehen- 

 sive studies are made of nuclear processes, including fundamental 

 nucleon-nucleon interactions, tests of charge-symmetry of the 

 nuclear force, near-threshold production of plons, and detailed 

 nuclear structure efforts throughout the periodic table. 



Date of Construction : 1969-75 (operational 1976). 



Construction Cost ; Original ; $10 million 



1984 $$ ; $30 million 



Present International Cooperation 



Natlonallty(s) of Ownership ; U.S. 

 Nationality(s) of Operational Funding ; U.S. 

 Nationality(8) of Management Staff ; U.S. 



Natlonality(s) of Researchers : 350 scientists from 60 Institutions 

 from 13 countries. 



Potential for Future International Cooperation : The addition of a 

 "Cooler" ring (see below) will enhance the attraction of this 

 facility to foreign scientists. 



Other Information : Construction of a "Cooler" Storage Ring began in 



FY83 (total estimated cost, $6 million) with $5.4 million provided 

 to date and with $0.6 million to be provided in FY86. The "Cooler" 

 will Introduce new technology into nuclear physics by providing 

 charged particle beams of light ions with very low emlttance, 

 small energy spread. It will make practical the use of ultra-thin 

 targets without loss in beam luminosity. 



The application of Cooler ring technology to nuclear physics 

 was initiated at lUCF. Dr. Pollock, who heads the construction 

 projects, has cooperated and consulted with several European 

 laboratories which are undertaking this technology for complemen- 

 tary nuclear physics research facilities.
