Abstract :
Beyond typical, open-loop or feedback use, fast, turn-by-turn bunch monitors provide recursive data that determines system dimensionality d and K-entropy whose time fluctuations provide useful diagnostic tools. For injection and extraction, one can study variations in the dimensionality of the attractor with matching, jitter, current and tunes. Comparison to dynamical models then helps to optimize control. Experimental and theoretical examples and their signatures are discussed, e.g. the evolution of the distribution function after injection is studied as a solution of Liouville´s equation
