Abstract :
When a beam undergoes a collective oscillation its emittance tends to grow because of variations in betatron tune which are due to energy spread and chromaticity and to nonlinear lattice characteristics. The authors estimate the emittance growth in the SSC (Superconducting Super Collider) caused by the measured ground motions at the SSC site and by beam-beam effects in the Jostlein beam-centering scheme.<>
