104 ACTIVITY REPORT 2021 Fig. 2 : TPS 27A beamline viewed upstream from STXM. Fig. 4 : Photograph of gas cell assemblies in situ to STXM and recorded offline test results. Fig. 3 : Photograph of the epoxy-granite-supported STXM chamber at TPS 27A1 and key components inside the chamber invar struts to diminish the vibration from the ground. The relative motion between the ZP and a sample is another key parameter that requires instant compensation during image acquisition. A differential-type laser interferometer feedback-control system is implemented to maintain the required stability. A photograph of the STXM endstation and key components inside the microscope chamber are shown in Fig. 3 . STXM is a microscope suitable for diverse applications including magnetism, polymer sciences, environmental science, and energy science. In 2021, we implemented several in-operando systems at 27A1 to expand the capabilities of STXM. The photograph shown at the top of Fig. 4 is one experimental configuration in which a gas cell capable of temperature and biasing controls is connected to the sample holder. An initial test result with N 2 gas indicated that the cell can maintain 10,000 pa and reach 500 o C. TPS 27A2 PRINS Station TPS 27A2 is the home of the PRINS station. The core of the station is a microscope that aims to work on photoelectron-related imaging and nano-scale spectra through a combination of an imaging-type electron column integrated with a hemispherical electron-energy analyzer
