Abstract White-beam slits are precision high heat load devices used on beamlines of the Advanced Photon Source (APS) to trim and shape the incoming x-ray beam before the beam is transmitted to other optical components. At the APS, the insertion devices that generate the x-ray beams are very powerful. For example, the heat flux associated with an x-ray beam generated by undulator A will be on the order of 220 W/mm{sup 2}at the L5-20 slit location (about 27.5 m away from the insertion device) at normal incidence. The total power is about 6 kW. Optical slits with micron-level precision are very difficult to design under such heat flux and total power considerations. A novel two-metal composite slit has been designed to meet the diverse thermal, structural, and precision requirements. A commercial code, ANSYS, has been used as the finite element source for the analysis of the optimized design for the set. {copyright} {ital 1996 American Institute of Physics.}
