Description

This paper presents an overview of the beam intensity measurement system for the C-band photocathode electron gun platform, detailing the observed phenomena during measurements and the associated experimental investigations. The system’s design, operational principles, and key components are introduced, followed by an analysis of critical measurement results and unexpected behaviors, such as dark current interference and beam instability. Corresponding experimental validations and optimization strategies are discussed to enhance measurement accuracy and platform performance, providing insights into the dynamic characteristics and reliability of the electron gun system.
