Influence of high energy electron irradiation on beam parameters measurement system

The paper presents the experimental layout and characteristics of the beam parameters measurement system for linear induction accelerator, and analyzes the change of electronic components of the system under high energy electron irradiation. Then measures for component protection are investigated. Under strong electromagnetic interference, high speed signals can be transmitted by using fiber to maintain the narrow pulse with small delay and jitter; using compact embedded computing can improve the system's immunity to electromagnetic interference.
