High-efficiency beam extraction and collimation using channeling in very short bent crystals.
A silicon crystal was used to channel and extract 70 GeV protons from the U-70 accelerator with an efficiency of 85.3+/-2.8%, as measured for a beam of approximately 10(12) protons directed towards crystals of approximately 2 mm length in spills of approximately 2 s duration. The experimental data follow very well the prediction of Monte Carlo simulations. This demonstration is important in dev...

In the last years a new method of beam extraction from accelerator ring based on using bent crystals is successfully developed. The advantages of the method are simplicity of implementation, possibility to combine with collider mode and internal targets, and small magnitude of intensity pulsations in time. The method is also very convenient for applying in a collimation system, a crystal is use...

متن کاملChanneling of high-energy particles in bent crystals ± Experiments at the CERN SPS
During the latest decade, experiments have been performed at the CERN SPS to investigate the use of high-energy channeled nuclei in bent crystals for extraction, beam splitting and beam bending. An understanding of channeling in a bent crystal with extraction and de ̄ection eciencies for dierent energies, crystal types and ions has been developed. Furthermore, the long-standing question of rad...
متن کاملSelf-collimation and beam splitting in low-index photonic crystals
We study self-collimation and beam splitting in low-refractive-index photonic crystals created within chalcogenide glass. We propose a beam splitter structure that allows direct experimental verification of photonic-crystal effects at optical wavelengths in a straightforward and definitive manner. The beam splitter provides angular separation of 90 using a highly compact spatial footprint, thus...
