E. Todesco et al., NERO - A CODE FOR THE NONLINEAR EVALUATION OF RESONANCES IN ONE-TURN MAPPINGS, Computer physics communications, 106(1-2), 1997, pp. 169-180
We describe a code that evaluates the stability, the position and the
width of resonances in four-dimensional symplectic mappings. The code
is based on the computation of the resonant perturbative series throug
h the program ARES, and on the analysis of the resonant orbits of the
interpolating Hamiltonian. The code is dedicated to the study and to t
he comparison of the nonlinear behaviour in one-rum betatronic maps. (
