Donald S. Hall, PhD. is a Canadian retired theoretical physicist who has worked in the nuclear power industry. Working in Instrumentation and control he first did research in the design of self-powered neutron detectors. These measure the power distribution in reactors. That involved simulations of the detector response to various compositions. He then developed software for the travelling flux detector used to map neutron flux in a reactor. It meant a lot of night shift work at the NRU reactor testing things along with his technicians. Ultimately they successfully tested it on one of the running Bruce power reactors.

Don then worked in on industrial tomography. That is like the CAT scans they have in hospital, except it is for valves and pipes. He developed the computer programs to run it and analyze the results and sometimes helped the technicians assemble the equipment.



Don then shifted to Artificial Intelligence first working on development of The Intelligent Colony Counter, a way for biologists to scan petri dishes. This combined computer vision and artificial intelligence

He then shifted to the use of AI in industrial risk assessment where he was the lead coder in a major international project called REX (Risk Expert). This had him collaborating with some of Canada’s leading experts in Artificial Intelligence.
Prior to retirement he was a member of the Canadian Association of Physicists.

Don has presented papers at, or attended, scientific conferences including the Canadian Association of Physicists, the Canadian Nuclear Society, the Institute of Electrical and Elecronic Engineers, and the International Symposium on Laboratory Robotics.
In addition to conference proceedings, Don has published a number of public papers including publishing in the IEEE Transactions in Nuclear Science, Molecular Physics, the Canadian Journal of Physics, and AECL papers. But most of the work he authored was restricted at a limited to named distribution level or commercial proprietary.
