Abstract

The optimum collimator location and the choice of their apertures with the purpose of decreasing the flux of outscattered protons in a circle is considered. The analytical and computer graphic methods are used for the solution of this task. Statistical modeling of the beam forming process is made for the UNK and sources of lost protons are defined. With the help of the scattered proton traces from the system and special curves for the correct installation of collimators can be defined. The optimum set and efficiency of collimators can be defined by showing collimator jaws on the phase planes in the scraper. Also the advantages of systems with an scattering target are considered. It is shown, that the losses in the circle are ~0 05% from all scraped protons at UNK
