The high heat load at the surfaces of the first x-ray optical elements at the APS requires special measures to be taken to more completely utilize the beam. A conceptually new design for such an element, proposed, realized, and tested by M. Hart and conveniently called {open_quote}{open_quote}matchbox,{close_quote}{close_quote} is to be implemented at the IMCA-CAT BM beamline as the first monochromator crystal. The requirements of the IMCA-CAT companies for the BM beamline dictate that an optimization of the design is made for a given x-ray energy range E=13 keV {plus_minus}1 keV. A modification of the original design to improve the vacuum compatibility of the device was made in collaboration with M. Hart. A FEA optimization of the geometry is made using the ALGOR and ABAQUS programs. Determination of the resulting slopes and the useful crystal surface after the best compensation of the thermal distortions are also made. The surface profile obtained by the FEA study was used to perform a ray-tracing analysis of the IMCA-CAT BM beamline. The results of the ray-tracing study will be presented. {copyright} {ital 1996 American Institute of Physics.}
