Channeling & Crystal Collimation
The report presents an overview the results of IHEP activity in the field of study and using bent crystals to steer high-energy particle beams obtained during 1987-2012. The hardware installed to study crystal beam splitting, collimation and extraction is described. It has been shown that the crystal deflectors developed are capable of sustaining long-term operation to deliver high-energy...

Channeling & Crystal Collimation
Study of crystal assisted collimation has been continued at the CERN SPS for different energies of stored beams using 120 GeV/c and 270 GeV/c protons and Pb ions with 270 GeV/c per charge. A bent silicon crystal used as a primary collimator deflected halo particles in channeling regime directing them into the tungsten absorber. A strong correlation of the beam losses in the crystal and...

Channeling Radiation & Related Phenomena
ABSTRACT
The motion of a charged particle in a one-dimensional periodic potential of the Krönig-Penney type is considered. The energy band structure, Bloch wave functions in coordinate and momentum representation are investigated in detail. Two sharply distinguished groups of states, i.e. below-barrier and above-barrier, are extracted and the role of both of them in the channeling of...
