WEYBB5	A Crab-Crossing Scheme for Laser-Ion Beam Applications	639
	A.V. Aleksandrov, S.M. Cousineau, T.V. Gorlov, Y. Liu, A. Rakhman, A.P. Shishlo ORNL, Oak Ridge, Tennessee, USA
	Lasers have recently been used in many applications to H⁻ beams, including laser charge exchange, laser wire scanners, and laser temporal pulse patterning. The H⁻ beam in these applications has wide variation ofμpulse length width dependence on focusing of the RF cavities, energy spread of the beam, and space charge forces. Achieving the required laser pulse length for complete overlap with the H⁻ can be challenging in some scenarios when available laser power constrained. The scheme proposed here utilizes a crab-crossing concept between the laser and the ion beam to achieve overlap of a short laser pulse with an arbitrarily long H⁻ beam pulse. An experiment to test the hypothesis in the context of H⁻ charge exchange is described.

WEPLH10	Efficiency Estimation for Sequential Excitation Laser Stripping of H⁻ Beam	827
	T.V. Gorlov, A.V. Aleksandrov, S.M. Cousineau, Y. Liu, A. Rakhman ORNL, Oak Ridge, Tennessee, USA
	Funding: ORNL is managed by UTBattelle, LLC, under contract DEAC0500OR22725 for the U.S. Department of Energy. A new laser stripping scheme for charge exchange injection of H⁻ beam is considered. The sequential scheme for the planned demonstration experiment includes two step excitation that requires much smaller laser power compared to the traditional 1-step excitation. The new scheme can be applied to a wider range of H⁻ beam energies and provides more flexibility on the choice of laser frequency. In this paper we discuss the two-step excitation method and estimate laser stripping parameters and stripping efficiency for the SNS accelerator and its future H⁻ energy upgrade to 1.3 GeV.
