EUROPEAN ORGANIZATION FOR NUCLEAR RESEARCH CERN{PS/96{12 (PA) 6 February 1996 PLATO: A PROGRAM LIBRARY FOR THE ANALYSIS OF NONLINEAR BETATRONIC MOTION

Plato: a Program Library for the Analysis of 4d Nonlinear Transverse Motion

The PLATO (Perturbative Lattice Analysis and Tracking tOols) program, a program library for analyzing fourdimensional betatronic motion in circular particle accelerators is presented. The routines included in this library provide both the resonant and the nonresonant perturbative series that approximate nonlinear motion (normal forms); standard numerical tools such as the Lyapunov exponent, fre...

European Laboratory for Particle Physics Cern -sl Division Dynamic Aperture Estimates and Phase Space Distortions in Nonlinear Betatronic Motion

Symplectic mappings which modelize the 4D betatronic motion in a magnetic lattice are considered. We deene the dynamic aperture in terms of the connected volume in phase space of initial conditions which are bounded for a given number of iterations. Diierent methods for a fast estimate of this quantity are given; the analysis of the associated errors and the optimization of the integration step...

European Organization for Nuclear Research Cern - Ps Division (rf) Tomographic Measurements of Longitudinal Phase Space Density

Tomography is now a very broad topic with a wealth of algorithms for the reconstruction of both qualitative and quantitative images. One of the simplest algorithms has been modified to take into account the non-linearity of large-amplitude synchrotron motion. This permits the accurate reconstruction of longitudinal phase space density from one-dimensional bunch profile data. The method is a hyb...

Beam parameters in CERN’s Proton Synchrotron (PS) accelerator must be controlled (and measured) with tighter precision than ever before to meet the stringent requirements of the Large Hadron Collider (LHC) programme. A non-destructive beam profile measurement system would be a valuable diagnostic tool. To this end, we measured N2 and Xe gas scintillation absolute cross-sections and lifetimes fo...
