National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

RFOFO Cooling Ring: Simulation Results.

DE200415006429

Publication Date	2003
Personal Author	Berg, J. S.; Fernow, R. C.; Gallardo, J. C.; Palmer, R. B.
Page Count	12
Abstract	Designs for neutrino factories and muon colliders use ionization cooling to reduce the emittance of the muon beam prior to acceleration. Current baseline designs make use of linear channels that only cool the beam in transverse phase space. However, there has been considerable progress over the past two years in achieving 6-dimensional ionization cooling in cooling rings. At present the most realistic modeling has been done for the RFOFO ring. Alternating polarity solenoids provide transverse focusing. The bending field is provided by alternately tipping the axis of the solenoids above and below the orbital midplane. A short cell length is used to obtain a small beta function with a reasonable value of the solenoid field strength. Wedge-shaped absorbers are placed in the beam path at locations where the solenoidal field changes direction. Most of the lattice cell is filled by RF cavities to restore the energy lost in the absorbers.
