  A new IR beamline has been scheduled at TPS beam-line construction Phase III. The new beamline optical design is following the structure of the existed TLS IR beamline. However, the focusing mirrors has to be re-deign according to different situation. These KB type mirrors (HFM and VFM) are same thickness flat stain-less plates assembled with bending arms and bended with single motor each to fit quintic polynomial surface pro-files for focusing and also modifying arc source effect of bending section. For a same thickness plate in addition with the bending arms effect to form a desired polynomi-al surface profile, it demands specific width distribution. With the drawing method and FEM iteration simulation, the optimized surface polynomial equation and width distribution design of the mirror plates were defined. The detailed design sequences will be described in this paper.

The next generation light sources will require x-ray optical components capable of handling large instantaneous and average power densities while tailoring the properties of the x-ray beams for a variety of scientific experiments. Diamond being radiation hard, low Z material with outstanding thermal properties is proposed for front pre-focusing optics applications. Euclid Techlabs had been developing x-ray refractive diamond lens to meet this need. Standard deviation of lens shape error figure gradually was decreased to sub-micron values. Post-ablation polishing procedure yields ~ 10nm surface roughness. In this paper we will report on recent developments towards beamline-ready lens including packaging and compound refractive lens stacking. Diamond lens fabrication is done by femtosecond laser micromachining. We had been using this technology for customization of other beamline components. Several application cases will be highlighted in this presentation: diamond anvils, x-ray flow cells and in-beam mirrors.
