Chalk River Plans for Intense, Continuous Neutron Source

Chalk River Nuclear Laboratories of Atomic Energy of Canada, Ltd. hopes to build a device called the “Intense Neutron Generator” that will produce $1016 thermal neutrons/cm2/sec$ continuously. In the design a linear accelerator produces a 65‐milliampere continuous beam of 1‐GeV protons that strikes a target of liquid lead–bismuth eutectic; neutrons come off through spallation reactions.
