  DESCRIPTION  This series contains the technical and 
               administrative records of the Medium Energy  
               Physics Division, which conducted basic physics 
               research in collaboration with universities 
               throughout the world. Most of the collection deals 
               with basic physics research,  however, some 
               information on biomedical research, particularly a 
               pion therapy program is included. Pion therapy was 
               a treatment at the Los Alamos Mason Physics  
               Facility (LAMPF) using subatomic particles called 
               pions to treat 225 cancer patients  between 1974 
               1981. The series contains project proposals, 
               construction records, and  biomedical research 
               records. A folder title listing is available. 
               Collection number  A 91 011.
