Inverse logarithm decay of long-term dynamic aperture in hadron colliders

The long-term behaviour of the non-linear single-particle dynamic aperture is considered for the 4D Henon map. The dynamic aperture is defined as the average of the particle loss boundary over several ratios of emittances. Using this definition, survival plots turn out to decay with the inverse of t...

description The long-term behaviour of the non-linear single-particle dynamic aperture is considered for the 4D Henon map. The dynamic aperture is defined as the average of the particle loss boundary over several ratios of emittances. Using this definition, survival plots turn out to decay with the inverse of the logarithm of the number of turns. We also compare the extrapolation of the dynamic aperture with the prediction of the maximal Lyapunov exponent.
