Hadron beams develop intensitydependent transverselongitudinal correlations within radiofrequency quadrupole (RFQ) accelerating structures. These correlations are only visible in sixdimensional phase space and are destroyed by reconstructions from lowdimensional projections. In this work, we estimate the effect of artificial decorrelation on the beam dynamics in the Spallation Neutron Source (SNS) linac and Beam Test Facility (BTF). We show that the evolution of a realistic initial distribution and its decorrelated twin converge during the early acceleration stages; thus, lowdimensional projections are probably sufficient for detailed predictions in highpower linacs.

Basic principles of laser assisted charge exchange injection for H⁻ ion andH^{0} beams are presented. Theoretical aspects of electromagnetic interaction of laser with hydrogen atom and H⁻ ions are discussed. Laser excitation, photoionizatio and interaction of atoms and ions with a strong electromagnetic field are discussed and compared. Different techniques of LACE for stripping of high current stochastic beams are presented. The optimum parameters of LACE are estimated and compared for various ion beam energies. Experimental development of laser stripping at the SNS are reviewed. Future plans of LACE at the SNS and JPARC are discussed.
