Raymond Klann has been with Argonne for more than 21 years and is currently the manager of the Radiological Detection and Response Section of the Nuclear Engineering Division. He is an expert in radiation detector development and testing, and algorithm development for radiological search. His area of expertise is also in experimental nuclear techniques, nuclear measurements, radiation transport analysis, and reactor physics.
Klann’s recent area of research has focused on gamma-ray and neutron detectors, detection systems, and algorithms for radiological search applications for homeland security. His work on semiconductor-based neutron detectors and systems for detecting and tracking radioactive sources in real-time has resulted in four patented technologies with three more pending.
Previously, Klann led an international research collaboration between the U.S. Department of Energy (DOE), Argonne, and the Commissariat a l’Energie Atomique Cadarache Research Center. This program, called OSMOSE, was conducted to improve integral neutron cross-sections of minor actinides. It included experimental measurements of reactivity-worth of minor actinide samples in different reactor spectrum to improve neutronic predictions of advanced nuclear fuels.
Klann also led the experimental program for the DOE Advanced Accelerator Applications Program. Argonne collaborated with Los Alamos National Laboratory, and the University of Nevada-Las Vegas to measure neutron production rates, neutron reaction rates, and neutron cross-sections of uranium, plutonium, minor actinides, and other materials of interest for development of accelerator-driven systems for power production and minor actinide burning concepts.
Klann’s earliest research focused on experimental nuclear techniques for the measurement of uranium and plutonium content in spent nuclear fuel elements, neutron radiography of highly-radioactive samples, and development of fast neutron radiography.
