Abstract :
As a part of the RHIC Spin project, the KEK optically pumped polarized ion source (OPPIS) is being upgraded at TRIUMF, and will then be installed at BNL. This new source will deliver >100 times more current than the existing BNL polarized H- source. In order to transport and accelerate this more intense polarized beam efficiently, a new 35 keV low energy beam transport (LEBT) line has been designed. Each beamline element has been designed to minimize aberrations using 2D and 3D-field analysis. Spin motion and beam optics were tracked from the ionizer cell in the source to the 200 MHz RFQ, including 3D-field effects
