An 18 cm by 18 cm photo-etch depiction of the High Current Test Facility (HCTF) mounted on a wooden base. The HCTF, located in Bldg. 610 at CRNL, was part of a program investigating electronuclear breeding – a process for producing intense neutron sources by spallation through the collision of high energy protons with heavy elements. The “electrically-produced” neutrons could then be captured in a thorium blanket around the accelerator target to produce fissile material. A retirement gift donated to the Society.
