BATES LINEAR ACCELERATOR CENTER 

 Massachusetts Institute of Technology 

 U.S. Dept. of Energy 



"Big Science" Descriptor ; Nuclear physics 



Description of Facility/Instrument ; This facility supplies very high 

 quality electron beams with energies up to 750 million electron 

 volts. The beams are generated by a linear accelerator and a 

 beam recirculation system. The experimental program has centered 

 on high-preclslon experiments which resolve complicated nuclear 

 structures. A growing program of coincidence measurements is 

 addressing a variety of important questions including nuclear 

 collective motion at high excitation energy, nuclear reaction 

 mechanisms, and fundamental properties of few-nucleon systems.

Because nuclear physics is an International activity, 

 with knowledge freely shared among its practitioners, this 

 laboratory has extensive interactions with people and insti- 

 tutions In foreign countries. 



More than 95 percent of researchers working at DOE 

 nuclear physics accelerators are from U.S. institutions. On 

 approximately equal and reciprocal bases, U.S. nuclear sci- 

 entists use foreign facilities. 



A current collaboration involves investigators from 

 the University of Alberta, Canada, and from SATURNE in 

 France. Foreign contribution to detector equipment Includes 

 a polarization polarlmeter and scintillation detectors. 



Potential for Future International Cooperation ; Beam time at this 

 facility is available %rtthout charge for the best research 

 proposals worldwide.
