    "abstract": "We present theory for coherent effects observed in crystal collimation\nexperiments that is in good quantitative agreement with RHIC and Tevatron data.\nWe show that coherent scattering in a bent crystal strongly amplifies beam\ndiffusion, with an effective radiation length shortened by orders of magnitude\ncompared to amorphous material. This coherent scattering could replace the\ntraditional amorphous scattering in accelerator collimation systems. We predict\nthat crystal collimation for negative particles can be as strong as for\npositives, unlike with channeling effect. This opens a principle way for\nefficient crystal steering of negative particles at accelerators. It can be\ndemonstrated with antiproton crystal collimation at the Tevatron. We predict\nstrong effects for the upcoming Tevatron experiment, for protons and\nantiprotons.",
