Description: 
This institute possesses some outstanding equipments that enable it 
to carry out a variety of studies in the field of high-energy physics and 
nuclear physics. The Institute has a M-2 computer, a cyclotron, and a 7-Bev 
strong-focusing proton synchrotron. They are presently engaged in studies of 
nuclear reactions, structure of nucleons, and beta decay, and have undertaken 
bubble-chamber studies and neutronographic studies of alloys. Much of the 
high-energy-physics equipment used at the Institute was developed there.
