Outline of Final Research Achievements

We performed the actual design and partial fabrication of this instrument for high intensity proton beams of the J-PARC Main Ring. The studied contents were summarized to five points as follows. (1) From the examination of the beam condition and the measurement of the background, we confirmed enough higher signal vs. noise ratio. (2) We developed the main optical system made of aluminum alloy to use in a vacuum. (3) We designed a vacuum system and the interlock which did not deteriorate the vacuum environment of the Main Ring. (4) We calculated the impedance of the apparatus for the circulating proton beam and it is confirmed that there was no factor which significant affects the beam. (5) We mounted the measuring equipment of a radiation-hardened image intensifier to other profile monitors and the effectiveness was demonstrated.
The vacuum chamber is under fabrication and the beam measurement will be started by the end of the H28 year with the proton beam of power of over 450kW.
