Notes:
In this article, the design, fabrication, prepolish coating, and polishing of a reaction-bonded (RB) internally cooled silicon carbide (SiC) mirror is described. The mirror was developed from a mold of SiC powder in a near-net shape and then infused with silicon vapor to make a dense mirror substrate. The mirror surface was then rough polished, coated with a thin layer of SiC, and polished to a final fine finish. The design and manufacturing of this mirror—intended to be used as a multilayer substrate on a high-heat-load undulator beamline—are described, and data on the surface figure and finish are provided. This type of mirror can provide an attractive alternative to internally cooled silicon mirrors. Because the substrate is made in one piece, it avoids the frit or metal bonding that is usually necessary with silicon substrates. Advantages of RB SiC mirrors include lower cost and higher reliability. © 2002 American Institute of Physics.
