A 4.3 Tesla superconducting wiggler will be used to produced x-rays of total power of approximately 56 kW in 8 keV ' 200 keV range. The nominal horizontal fan of ~ 10 mrad will be split into three closely spaced beams of 0.2 mrad, 1.0 mrad and 0.2 mrad fans. Each beam is required to have a frontend slit with four distinct apertures. The conventional L-shape design of the slit is not feasible for these closely spaced beams because of constraints on side cooling and horizontal travel of the slits. In this paper we propose two solutions for these slits using a beam pass-through design, vertical-only travel and optimized cooling configurations.
