First observation of luminosity-driven extraction using channeling with a bent crystal
Luminosity-driven channeling extraction has been observed for the first time using a 900 GeV circulating proton beam at the superconducting Fermilab Tevatron. The extraction efficiency was found to be about 30%. A 150 kHz beam was obtained during luminosity-driven extraction with a tolerable background rate at the collider experiments. A 900 kHz beam was obtained when the background limits were...
متن کاملExperimental evidence of planar channeling in a periodically bent crystal
The usage of a crystalline undulator (CU) has been identified as a promising solution for generating powerful and monochromatic γ -rays. A CU was fabricated at Sensors and Semiconductors Lab (SSL) through the grooving method, i.e., by the manufacturing of a series of periodical grooves on the major surfaces of a crystal. The CU was extensively characterized both morphologically via optical inte...
متن کاملHigh-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...
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 کاملSpontaneous and stimulated undulator radiation by an ultra-relativistic positron channeling in a periodically bent crystal ?,??
We discuss the radiation generated by positrons channeling in a crystalline undulator. The undulator is produced by periodically bending a single crystal with an amplitude much larger than the interplanar spacing. Different approaches for bending the crystal are described and the restrictions on the parameters of the bending are discussed. We also present numeric calculations of the spontaneous...
