Simulations of Fringe Fields and their Effects in Electrostatic Storage Rings — •Christian Glaessner, Carsten Welsch, Kai Uwe Kühnel, and Alwin Schempp — IAP Frankfurt, Robert-Mayer-Str. 2-4, D-60325 Frankfurt am Main

A quarter ring section of an electrostatic storage ring which is able to store particles up to a total energy of 50 keV is being built up at IAP Frankfurt. The used beam transport elements are dipoles (10circ- and 70circ-deflectors) and quadrupoles. Fringe fields exist in all of these elements. These fringe fields have effects on phase space couplings, the actual useable fields, the angles of deflection and also on the dynamic aperture of the machine.

The poster shows simulations of these fringe fields and their effects as well as possible solutions to reduce all these effects.
