  The beamline group is actively doing two new projects. One project is developing of standardization and modularization beamline components for the Taiwan Photon Source (TPS) and Taiwan Light Source (TLS) beamlines. The components including the high heat load masks, white/mono beam slits, phosphor screens type beam monitor system, beam shutters, common chambers, and support tables/stands, are selected as the standards so far. Many advanced concepts and materials are applied for the developing components to improve their stability and reliability. The other project is planning to design a monitor and control system for the beamline components. Some EPICS compatible instruments are being partially tested and will be applied to the new beamlines at TPS.[1-3] The log of beamline status for all beamlines will be recorded and stored in an archive. The purpose of these projects will save not only the cost but also the manpower on construction for several beamlines in time.

  By contributions of the generic beamline components project in recent years, modular mechanisms such as mask, X-ray beam position monitor (XBPM), photon absorber (PAB), and screens were used in every beamline of the Taiwan Photon Source (TPS). However, these beamline components were designed for ID beamlines, so they should be redesigned for bending magnet (BM) beamlines. The TPS 24A, Soft X-ray Tomography (SXT) beamline, is one of the bending magnet (BM) beamlines in the second construction phase at the TPS. This 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 2.82·1011 photons/second with resolving power 2000, the beam size is 50 um × 60 um (V × H, FWHM) and the beam divergence is 1.73 mrad × 1.57 mrad (V × H, FWHM). Since the TPS 24A is commissioning during these months, this paper generally makes a discussion about the XBPM in TPS 24A to help further improvement in the future.
