Abstract
Some experiments performed at bending magnet beamlines at the Advanced Photon Source (APS) will benefit from a focused photon beam. A commercial sagittal focusing bender that uses a simple rectangular plate as the diffraction element could be utilized for this purpose. However, the thin rectangular diffracting plate, specified by the manufacturer, is susceptible to anticlastic bending. A simple ribbed plate that utilizes this commercial bender but that reduces anticlastic bending is proposed as a solution. This design uses a pair of sufficiently stiff ribs on the diffracting surface, which substantially suppresses anticlastic bending. The finite element analysis (FEA) method was used to predict the overall structural response of this sagittally bent plate and its anticlastic distortion. Results are compared with unribbed plates showing an effective reduction in anticlastic bending.
