Objective

The research program aims to develop a high-efficiency technique for steering of halo particles in a large hadron collider using bent channeling crystal. The technique can be used to strongly enhance the efficiency of beam cleaning system if a bent crystal serves as a primary element in the LHC beam collimation system, reducing the beam-related backgrounds in the collider experiments by an order of magnitude as estimated. Whenever required, the same technique can be used for slow parasitic extraction from the LHC halo without interfering with collider work, with extraction efficiency between 50-90% according to simulations.
