A previous publication [P. D. McChesney, “Multi-plate interceptive electron beam energy diagnostic—Theoretical design,” AIP Adv. (submitted)] reported a new interceptive electron beam kinetic energy measurement technique based on the beam penetration depth within a stack of conductive plates and gave results on the theoretical design of such a device. This paper expands on this and gives further results on the actual implementation of the diagnostic. The device geometry and measurement electronics system are described in detail. A prototype version of the multi-plate diagnostic was fabricated and tested using an electron linear accelerator at the Idaho Accelerator Center (IAC). A high-precision magnetic spectrometer system was designed and built for the purpose of validating the multi-plate diagnostic’s energy measurement capabilities. It was found that the diagnostic provides electron beam energy estimates that are accurate to better than the 10% level.A previous publication [P. D.
