Abstract
A completely new approach to measure beam emittance is examined. It is based on measuring the decay rate of the coherent betatron-oscillation through nonlinear filamentation caused by lattice nonlinearity. Experimental results, computer simulations and an analytic approach using differential algebra are presented. This method may provide useful tools in measuring emittance at high brightness light sources, high luminosity particle factories and damping rings for linear colliders where emittance and coupling are expected to be very small
