About Ryuji Maekawa
Ryuji Maekawa is a Senior Cryogenic Research Professional at Oak Ridge National Laboratory, specializing in cryogenic systems since 2022. He has extensive experience in modeling and simulation, having previously worked at ITER Organization for 12 years.
Work at Oak Ridge National Laboratory
Ryuji Maekawa has been employed at Oak Ridge National Laboratory as a Senior Cryogenic Research Professional since 2022. His role involves the modeling of the Spallation Neutron Source (SNS) cryogenic system, which encompasses both 4K and 2K cold boxes. He has utilized two independent software tools for modeling and has successfully performed co-simulation to validate the control strategy for plasma operation scenarios, including fast events. Maekawa is also involved in the upcoming upgrade of a new 2K cold box for the SNS cryogenic system and is benchmarking the SNS cryogenic system model against design specifications, focusing on its validation.
Previous Experience at ITER Organization
Before joining Oak Ridge National Laboratory, Ryuji Maekawa worked at the ITER Organization as a Cryogenic Engineer from 2010 to 2022. During his tenure, he completed a dynamic simulation model of the ITER cryogenic system, which included three 25 kW class helium refrigerators operating in parallel and the Tokamak superconducting magnet system. His extensive experience at ITER contributed to his expertise in cryogenic systems and their operational dynamics.
Education and Expertise
Ryuji Maekawa earned his Doctor of Philosophy (PhD) in Nuclear Engineering and Engineering Physics from the University of Wisconsin-Madison, where he studied from 1989 to 1995. His academic background provides a strong foundation for his work in cryogenic research and engineering, equipping him with the necessary skills to tackle complex challenges in the field.
