  The secondary source slits have been developed for specific hard X-ray beam-lines at Taiwan Photon Source. Especially for Coherent X-ray Scattering and X-ray Nanoprobe beam-lines, severe specifications of the slits are more necessary to define proper beam sizes in horizontal and vertical directions at sample. The opening size of each pair of slits assembled orthogonally is usually needed to range within several microns, so the UHV-compatible piezo-driven stages with closed-loop system were adopted for the purposes of fine adjustment, precise positional accuracy and repeatability. To reduce X-ray scattering effect, the rectangular single-crystal film was bonded on the edge of the slit blade. The machined rotary weak-link structure and piezo-driven actuators were used to slightly adjust parallelism of each pair of the blades with the method of single-slit diffraction. To enhance structural and thermal stability, the granite plinths with specified shape were designed and the precise temperature controlling system will be set up recently. The overall design, mechanical specifications and procedure of testing for secondary source slits will be introduced in this paper.

  The TPS 24A, Soft X-ray Tomography (SXT) beamline, is one of the beamlines in the second construction phase at the Taiwan Photon Source (TPS). This bending magnet (BM) beamline has high flux in the range between 260 eV and 2600 eV. It is designed for transmission full-field imaging of frozen-hydrated biological samples. At the exit slit, the beam flux optimized in 520 eV is 282 billion photons/second with resolving power 2000, the beam size is 0.05 mm × 0.06 mm (V × H, FWHM) and the beam divergence is 1.73 mrad × 1.57 mrad (V × H, FWHM). By contributions of the generic beamline components project in recent years, modular mechanisms would be used in this beamline such as mask, X-ray beam position monitor (XBPM), photon absorber (PAB), and screens. However, these beamline components were designed for ID beamlines, so they should be redesigned for BM beamlines. This paper generally introduce these beamline components decided and redesigned for the TPS 24A. They will play important roles at the BM beam-lines in the future.
