The following 2 notes relate to orbit calculations in FFAG's.
Summary: This uses constant field on the orbit as Bruno does in his Mathematica implementation. It works just as well for FFAG's, of course.
Summary: This also works just as well for FFAG's. It gives expressions for orbit properties of separated-sector FFAG's which have reverse-field regions on either side of the dipole, called "gullies". This therefore applies particularly to the FFAG's considered by Mori's group, but is actually more general, since it also considers spiral.
The following were written at the early stages when different concepts were being considered for the TRIUMF KAON factory. They relate to the problem of matching a cw cyclotron to a pulsed synchrotron, and so are particularly relevant to the RIKEN application.
Summary: This is a proposal similar to ASTOR, for matching the cw TRIUMF beam to a 30 Hz synchrotron.
Summary: The purpose of this study was to determine the feasibility of stacking the TRIUMF cyclotron beam at radius about 300 inches (500MeV) by a controlled deviation from isochronism. Possible application to RIKEN. This is a different technique than "RF stacking" as in the ASTOR proposal, but has a similar effect.
Summary: As above.
