A new XAFS beamline which uses a pair of bent conical mirrors for collimation and focusing is under construction. A double crystal monochromator is placed between the two mirrors. This beamline is to provide high flux without sacrificing the energy resolution. Ray-trace results indicate that a bent conical mirror is not only a good approximation of a rotating paraboloidal, but also that of rotating ellipsoidal, mirror.
