X-Ray Beam Position Monitor in TPS 24A Beamline | |
|
||
| 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. | ||
