    "abstract": "While particle beam steering (and in particular, \"scraping\") in accelerators\nby bent channeling crystals is an established technique extensively tested at\nIHEP Protvino and other major high-energy labs, an interesting question is how\none could improve channeling capabilities by applying modern nanotechnology.\nTheoretical research of nanotube channeling was in progress over recent years.\nIn this work, we assess potential benefits from nanotube channeling for real\naccelerator systems. We report simulation studies of channeling in\nnanostructured material (carbon SWNT and MWNT) tested for possible serving as a\nprimary scraper for the collimation systems of hadron colliders. The advantages\nof nanostructured material as a potential choice for a primary scraper in a\nhigh-energy accelerator such as LHC or the Tevatron are discussed in comparison\nto crystal lattices and amorphous material. We evaluate physical processes\nrelevant to this application and reveal nanotechnology requirements.",
