The Oak Ridge Detector Laboratory (ORDELA, Inc.) is a privately owned corporation in Oak Ridge, Tennessee. ORDELA, Inc. was formed in 1984 to provide specialized products, services, and systems for the scientific and industrial research community. ORDELA, Inc. produces a line of position-sensitive proportional counter systems for the detection of x-rays, neutrons, and charged particles, and provides custom-made radiation detection instruments. Key staff members are Manfred K. Kopp, President and Daniel M. Kopp, Technical Director.

Manfred K. Kopp is a measurement scientist with over 30 years of experience in the field of nuclear instrumentation. He co-founded ORDELA after retirement from the Oak Ridge National Laboratory (ORNL) where he was a Senior Development Staff Member in the Instrumentation and Controls Division. He holds a B.S. degree in Electrical Engineering from the Buenos Aires University of Argentina and the University of Tennessee, a M.S. degree in Electrical Engineering from the University of Tennessee, and is a Registered Professional Engineer. At ORNL, he pioneered the development of RC-encoded, position-sensitive proportional counters and their associated position-decoding circuitry. Earlier, at the Argentine Atomic Energy Commission, he developed nuclear instrumentation for the industrial application of radioisotopes. At present, Mr. Kopp is responsible for research and development of detectors and instrumentation. He has over 50 publications and 12 patents to his credit and is an internationally recognized expert in the fields of radiation detection instrumentation, and position-sensitive x-ray and neutron proportional counters.

Daniel M. Kopp is a development engineer with over 10 years of experience in the design of radiation measurement instrumentation. Mr. Kopp is the Technical Director of ORDELA, Inc. and is responsible for the design and development of all electronic products. Prior to his work at ORDELA, Inc., he was employed as a design engineer with Technology for Energy Corporation (TEC) for a period of nine years. While at TEC, Mr. Kopp was extensively involved in the development and installation of commercial radiation monitoring systems, reactor coolant-level monitoring systems, and fossil plant monitoring instrumentation. He has vast experience in the development, testing, calibration, and qualification of instrumentation for use in the nuclear industry. Mr. Kopp has authored several publications in the field of radiation detection instrumentation.
