Arthur Carpenter joined LLNL in 2010 after earning an MS in Electrical Engineering from UC Davis, specializing in solid-state device electronics. His thesis focused on developing a carbon nanotube-based field emission triode for X-ray imaging systems.

At LLNL, Arthur has contributed to over 25 X-ray, gamma-ray, and neutron diagnostic systems, as well as the Advanced Radiographic Capability (ARC) laser. He became the lead engineer for the Detector group in 2017 and an administrative group leader in 2019. From 2019 to 2021, he led a project on Germanium photodiode arrays for high-speed imaging.

Arthur collaborates with UC Davis, CEA/Laser Megajoule, and SLAC/FANL on advanced detector technologies. His technical interests include high-speed optical communication, micro/nano-fabrication, radiation-tolerant electronics, ultrafast CMOS sensors, and high-energy X-ray diode design. He is also passionate about systems engineering, facility integration, operations, and project management.
