Abstract: This paper presents voltage pulse and electron beam current measurement on the 10MeV LIA. The 10MeV LIA consists of an 1MV injector of 4 accelerating cavities and a post accelerator of 28 cavities. It’s electron beam transport line is more than 20m long. The cavity voltage pulses are measured with capacitive voltage probes and resistive voltage dividers. The voltage pulse of the injector and the post accelerator are measured by summing passively the signals from the capacitive voltage probes at the injector and the post accelerator respectively and then integrating them with RC integrators respectively. The electron beam currents along the accelerator are measured with resistance ring. By monitoring the image current on the inner pope wall, the beam intensity and position are obtained.
