SUBSTANCE CHOICE OF THE SCRAPER SYSTEM ELEMENTS

In this paper the functioning of scraper system elements at maximum radiation and thermal loads in different regimes of the system’s work is considering. Substance choice and design of system elements construction are made with pur-pose of prevention their thermal,mechanical and radiation destruction. The advantage of using scraper system with scattering target is shown. By simulation of the real scrap-ing process in UNK the maximum heating elements is de-fined during many circles and at different beam energies. The designed scraper system with W target and Cu scraper can scrape up to 10 % of full intensity 61014p at the en-ergy E = 70 GeV and up to 1 % at E = 600 GeV.
