Description

At Taiwan Photon Source (TPS), the main liquid-nitrogen (LN2) transfer line of length 600 m for beamline endstations was installed in 2015. It formerly supplied LN2 to maximum 24 beamline endstations. Beamline endstation 15A (TPS 15A), of which the aim is to determine 3D crystal structures from micro-scale single crystals and non-ambient conditions. We designed and self-manufactured one LN2 transfer line according to the requirement of TPS 15A, to supply LN2 into the both end station and 50L phase separator. The 50L phase separator was constructed to provide high quality of LN2 and pressure stability to the chiller of double-crystal monochromator (DCM), to prevent the thermal deformation of the crystal. In this paper, we present the design and manufacturing of LN2 pipeline, 50L phase separator and pressure regulator. The heat-load measurement and performance test was also presented and discussed.
