Description

We have conducted the scraper irradiation test with the 3 MeV linac. The test piece of the scraper was irradiated by the H- beam up to particle number of 1.2E20. We measured the surface temperature of more than 3000degC using a high-speed radiation thermometer and observed the irradiation damage on the scraper by using the laser microscope. When the surface temperature exceeded 2900degC, the ionic current of carbon and the irradiation damage on the surface of the test piece rapidly increased. This paper describes beam irradiation test results of the scraper. (author)
