BEAMLINE GUIDE
NSRRC TPS 05A

Beamline Description

TPS 05A aims for difficult structures as well as routine data collection. The X-ray source of TPS 05A is a three meters long in-vacuum undulator (IU22), producing a high-brilliant X-ray beam. The X-rays are monochromated by a liquid-nitrogen-cooling Si double-crystal monochromator, and focused by a pair of Kirkpatrick–Baez mirrors. The focused beam size at the sample is 65 μm (H) x 36 μm (V) with photon flux of 1.1 x1013 photons/s at 12.4keV. Apertures are used to collimate the beam in the range of 50–5 μm. The beam divergence at the sample is less than 500 μrad (H) and 100 μrad (V), and the energy range is from 5.7 to 20 keV (wavelength 2.175-0.62 Å). Equipped with a high speed CCD area detector and a micro-diffractometer, TPS 05A is capable of not only shutterless data collection for much higher throughput and helical scan to mitigate the radiation damage but also grid scan to find the best diffraction areas or to locate micro crystals. The optional mini-κ goniometer of the high precision micro-diffractometer enables crystal reorientation. A robotic sample changer for automatically sample mounting and centering in installed, making the data acquisition more efficient. Substantial user-support, remote access and mail-in service are also provided.1 TPS Beamlines (n.d.) Retrieved May 13, 2020 from http://tpsbl.nsrrc.org.tw/bd_page.aspx?lang=en&port=05A&pid=1000
