Accurate measurement of the intense pulse electron beam transverse position is not only related to the technology of beam position monitor (BPM) design, machining and assembly, but also related to calibration of BPM. This paper describes the physical design of the calibrated device based on the measuring principle of intense pulse electron beam position monitor in linear induction accelerator. A coaxial line structure is used as the calibrated device. The axial length that affects the electromagnetic field at a given location and the position measurement affected by coaxial line with displaced inner conductor are analyzed in theory, the results determine the length and the characteristic impedance of the coaxial line. The extent of inner conductor displacement is determined by the calculated errors of beam position measurement. Pulse signal mismatch transmission in calibration, the PSpice simulation and experimental measurement are performed, and results show that a required pulse waveform is obtained.
