In the Japan Proton Accelerator Research Complex (J-PARC) 3-GeV rapid cycle synchrotron (RCS), transverse beam halo scraping for the injection beam is required to increase the output beam power. The transverse collimation system at the Linac-RCS beam transport line (L3BT) was utilized in a nominal beam operation because the area of the scraper section was contaminated when scrapers were working. In the summer-autumn period of 2013, we installed a new beam-halo scraper which had optimized scraper heads for mitigation of the radiation around the scraper system. In this poster, we report a preliminary result for a halo scraper at the L3BT.
