Allies intelligence agencies

As work proceeded at Los Alamos and elsewhere in America, Allied intelligence agencies had been following the atomic weapons projects underway in both Germany and Japan. In Japan the project was headed by Yoshio Nishina, who had studied under nuclear physicist Niels Bohr in Denmark and had set up the Riken Institute for Physical and Chemical Research in the Japanese capital of Tokyo. Nishina built two cyclotrons at the Riken Institute. Another key scientist was Ryokichi Sagane, who had studied under Emeset O. Lawrence at the University of California at Berkeley. 

The research described in this briefing was prepared for the United States Department of Energy. This research was conducted within the RAND National Security Research Division, which conducts research and analysis for the Office of the Secretary of Defense, the Joint Staff, the Unified Commands, the defense agencies, the Department of the Navy, the U.S. intelligence community, allied foreign governments, and foundations.
