Research Abstract

In order to improve the beam intensity and quality of high intensity proton accelerator, the beam diagnostic systems have been developed. A laser based photo neutralization beam profile monitor was constructed in J-PARC Linac. Beam current, position and profile had be confirmed to obtain the specifications of laser based beam profile monitor. Spatial profile of magnetic field to collect the photo ionized electrons was evaluated. Feedthrough and vacuum vessels were composed of radiation resistant materials for high intensity operation. Large current and low emittance negative ion beam have been obtained by fine tuning using the beam diagnostic system. Neutral particle component of negative ion beam by residual gas impact was also measured in Linac dump line. Beam diagnostic system have been played important role for high intensity beam operation, and these results are indispensable for development of laser based profile monitor.
