Arbitrary shapes, field content, contours
Opera field data plotted in the midplane for one quadrant and showing spiral sectors.
Tracking in a model non-scaling six-fold symmetric FFAG for horizontal (left pairs) and vertical (right, pairs) with 3rd (top), 5th(middle), and 11th-order (bottom) out of plane expansion, with focusing from an azimuthal field variation expressed as a single Fourier mode as well as edge focusing . With (left) and without (right) Expo symplectification is shown.
Advanced design and simulation of anIsochronous 250-1000 MeVNonscaling FFAG
General Parameters of an initial 0. 250 – 1 GeV non-scaling, near-isochronous FFAG lattice design
Clockwise: Matematica: Ring tune, deviation from isochronous orbit (%), and radius vs. momentum
Dynamic aperture at 250, 585, and1000 MeV – step size is 1.5 cm in the horizontal (left) and 1 mm in the vertical (right).
FACT tool developed by Particle Accelerator Corporation (PAC) and COSY
INFINITY developed by the Beam Theory and Dynamical Systems Group at
Michigan State University (MSU). Specically, it currently allows the analysis
of two types of accelerator specications, Fourier Gauss and Enge Edge, via de-
tailed high-order particle tracking as well as eld data export and visualization.
specications, are performed on a remote server provided and maintained by
PAC. The FACT FFAG GUI uses Oracle JavaWebStart technology to download
and run the COSY JavaGUI program that is capable of displaying the GUI to
the user and communicating her response to the server using industry standard
encrypted SSH channels.
by PAC for the simulation of a variety of FFAG type accelerators. COSYFACT
and the FACT FFAG GUI are built on top of the well known COSY INFINITY
scientic computation environment, consisting of COSY INFINITY, the COSY
INFINITY beam physics package, and the COSY JavaGUI, all developed and
licensed by MSU.
