LHC Machine Protection challenges for 2011 — •Tobias Bär — CERN, Genf, Schweiz — Universität Hamburg, Deutschland

The Large Hadron Collider has an unprecedented stored beam energy of up to 362MJ per beam. In 2011, 100MJ could be reached. In this talk, crucial machine protection challenges for 2011 and beyond are discussed. Especially, UFOs as potential show-stoppers are addressed. UFOs or "Unidentified Falling Objects" were first observed in July 2010 and are since then a major source of emergency beam dumps. They are prospectively micrometer sized dust particles that lead to fast beam losses when they interact with the beam. The state of knowledge and mitigation strategies are presented.
