Subcommittee Encourages U.S. to Join Canadian Kaon Factory

Since the mid‐1970s, “pion factories” in Vancouver, Los Alamos and Zurich have been providing medium‐energy experimenters in nuclear and elementary‐particle physics with π mesons in great profusion. These small accelerators generate high‐intensity beams of protons just energetic enough to make pions when they hit a fixed targe.
