Oriented Crystal Applications in High Energy Physics

Effective fields of atomic strings and planes, which govern fast particle motion in oriented crystals, hundreds and thousands times exceed that of superconducting magnets. These fields naturally find unique applications in high energy physics. Channeling effect of oscillatory particle motion in the field of crystal planes can be used for both high energy beam deflection and collimation. Strong crystal fields also can enhance both the gamma-radiation by electrons and electron-positron pair production by gamma-quanta. We consider possible crystal applications for the beam collimation of the Large Hadron Collider and Future Circular Collider and acceleration of electromagnetic shower development in lead tungstate crystals of the Compact Muon Solenoid of the Large Hadron Collider.
