Electrostatic toroidal bender and its fringe fields

Accelerator Physics 2025-07-30 v1 High Energy Physics - Phenomenology

Abstract

I describe the COSY-Infinity code GES that we have developed and used in various forms in the past 30 years to calculate maps to third order through electrostatic bend elements. It has been a mystery that COSY's in-built procedures ES, ESP and ECL disagreed with our own code. This note is intended to clarify the issue.
