Kay Chesnut

Kay Chesnut, Engineering Fellow, Radiation Effects Engineering, Raytheon Intelligence & Space at Raytheon Technologies has worked on commercial and military space systems and communication satellite hardware for almost 45 years at Hughes Aircraft, Boeing, and Raytheon.  She developed and delivered over 20 new systems during her career using new technologies that had to operate in harsh radiation environments, including both nuclear and natural environments. 

Kay’s first introduction to radiation effects started with the redesign of a space timing system to mitigate single event effects in 1982.  She started working extensively with the radiation community in 1993, collaborating on the then new technology insertion of a 500MHz digital GaAs direct digital synthesizer (DDS), formed a solid foundation for proper heavy ion testing at speed, and subsequently designing mitigation approaches for the high frequency effects on single event sensitivity (original single event effects tests were done at 100 kHz).  This DDS was used in a critical frequency hopping system.  The spirit of cooperation among key researchers, device manufacturers, and industry practitioners drew Kay to volunteer for other roles in radiation effects.

Kay has served as the Financial Chair for the IEEE’s 2003 NSREC, Local Arrangements Chair for the 2005 NSREC, 2009 NSREC Short Course Instructor (with Dr. Kirk Kohnen), Conference Chair of the 2011 NSREC, 2008 Radiation Effects Steering Group Secretary, and the 2012-2015 Radiation Effects representative on the IEEE Nuclear Plasma Sciences Society AdCom, Short Course Instructor for the 2021 NSREC short course “Challenges and Opportunities for Radiation Hardening in Advanced Technologies” on system-level hardening.  Kay was elected Executive Vice Chair of the Radiation Effects Steering Group in 2021 and became Executive Chair in 2024.
