Recent Progress on FFAGS for Rapid Acceleration

چکیده
Muon acceleration is one of the more difficult stages to develop for a Neutrino Factory or Muon Collider. The large transverse and longitudinal admittances which must be designed into the system and the rapidity with which acceleration must take place because of muon decay preclude the use of conventional synchrotron design. The approach here employs fixed-field architectures for muon acceleration; specifically, a fixed-field alternating gradient or FFAG accelerator. This paper explores the FFAG option, in particular addressing an adjustment in the rf phase which, although characteristic of fixed-field machines, becomes problematic in the context of rapid acceleration.

1.1 FFAGs for Muon Acceleration
Muons present unique challenges for acceleration. First of all, muons decay: this means that any acceleration must be rapid. A practical minimum is around 1 MV/m. This rules out traditional synchrotron designs, which contain a relatively small amount of RF per turn. One could have more RF per turn in a synchrotron, but then one runs into the challenge of ramping the magnetic fields sufficiently...
متن کاملRecent Results from Optimization Studies of Linear Non-Scaling FFAGs for Muon Acceleration
Because of the highly repetitive nature and simple cell structure of FFAG lattices, it is possible to automatically design these lattices. In designing an FFAG lattice, one will try to meet certain constraints and then minimize some cost function by varying any remaining free parameters. I will first review previously published work on optimized FFAG design. Then I will describe recent advances...
متن کاملID : 1088 ! Fixed Field Alternating Gradient Accelerators ( FFAG ) for Fast Hadron Cancer Therapy
Cancer accelerator therapy continues to be ever more prevalent with new facilities being constructed at a rapid rate. Some of these facilities are synchrotrons, but many are cyclotrons and, of these, a number are FFAG cyclotrons. The therapy method of “spot scanning” requires many pulses per second (typically 200 Hz), which can be accomplished with a cyclotron (in contrast with a synchrotron). ...

Recently, there has been a great interest in ultrahigh "eld particle acceleration driven by ultraintense laser pulses in plasmas. Although particle acceleration by laser "elds has been proposed since the beginning of the laser evolution, there has been tremendous progress in recent years. The laser-driven particle acceleration concepts are reviewed on the physics mechanism. In particular, the e...
متن کاملVERTICAL ORBIT-EXCURSION FIXED FIELD ALTERNATING GRADIENT ACCELERATORS (V-FFAGs) AND 3D CYCLOTRONS
FFAGs with vertical orbit excursion (VFFAGs) provide a promising alternative design for rings with fixed-field (e.g. superconducting) magnets. They have a vertical magnetic field component that increases with height in the vertical aperture, yielding a skew quadrupole focussing structure. Scaling type VFFAGs have fixed tunes and no intrinsic limitation on momentum range; they are also isochrono...
