Possibility to Measure the Poincar E Section Map of a Circular Accelerator
نویسنده
چکیده
Nonlinear beam dynamics is an important issue in accelerator systems. The Poincar e section map plays a basic role in characterizing and analyzing such a nonlinear system. Although many kinds of nonlinear beam dynamics experiments have been conducted, no direct measurement of a nonlinear map has been reported for an accelerator in normal operation mode. In this paper, we will show that it appears possible to measure the Poincar e section map of a circular accelerator to a surprisingly high order and accuracy based on present technology. Such measurements could signi cantly advance our understanding of the beam dynamics in an accelerator.

LETTER TO THE EDITORSome considerations on Poincar
The standard way to reduce a ow to a time{discrete dynamical system is by the technique of the Poincar e surface of section. We discuss the relationship between Poincar e maps obtained from diierent surfaces of section and give some considerations for practical application for this method.
متن کاملComparison of Heat Transfer Power of the Cooling Panel with Square Cross Section and Circular Cross Section in Electric Arc Furnaces Steelmaking by the use of Computational Fluid Dynamics
Steel pipes with circular cross-sections are usually used in cooling panels of electric arc furnaces. In the present study pipes with square cross-sections under equivalent conditions were used to obtain more information on the possibility of increasing the heat transfer and cooling efficiency. The results showed increased efficiency of the square pipe compared to the circular cross-section pip...
متن کاملPhase Space Reconstruction of Discontinuous Maps
Discontinuous mappings arise naturally in many physical applications, for example impacting oscillators. They also occur as Poincar e maps of smooth ows when the chosen Poincar e section is not everywhere transverse to the ow. We highlight the problems of reconstructing such maps from scalar measurements and propose a modiication of the method of False Nearest Neighbours to identify the minimum...
متن کاملComplete Poincar E Sections and Tangent Sets
Trying to extend a local deenition of a surface of section and the corresponding Poincar e map to a global one, one can encounter severe diiculties. We show that global transverse sections often do not exist for Hamiltonian systems with two degrees of freedom. As a consequence we present a method to generate so called W-section, which by construction will be intersected by (almost) all orbits. ...
متن کاملVisualizing Poincar E Maps Together with the Underlying Ow
We present a set of advanced techniques for the visualization of 2D Poincar e maps. Since 2D Poincar e maps are a mathematical abstraction of periodic or quasiperiodic 3D ows, we propose to embed the 2D visualization with standard 3D techniques to improve the understanding of the Poincar e maps. Methods to enhance the representation of the relation x $ P (x), e.g., the use of spot noise, are pr...
