Transverse beam halo is one of the most important beam parameters due to limit the performance of the high intensity beam accelerator. Therefore, the transverse beam halo measurement is required to increase the beam power of the J-PARC 3-GeV RCS. New beam halo monitor, which is combined a wire type beam scraper and some beam loss monitors, are installed in the extraction beam transport line. In order to use some beam loss monitors with a plurality of different sensitivities, it's ultra wide dynamic range can be achieved and beam profile including both of the beam core and halo can be obtained.

Rapid Cycling Synchrotron(RCS) of Japan Proton Accelerator Complex(J-PARC) is providing more than 300 kW of proton beam to Material and Life science Facility(MLF) and Main Ring(MR). Last summer shutdown, a new ion source was installed to increase output power to 1 MW. In order to achieve reliable operation of 1 MW, we need to reduce beam loss as well. Beam quality of such higher output power is also important for users. We present beam monitor systems for these purposes.
