ABSTRACT

  BL43IR is dedicated to infrared microspectroscopy. Although Foulier transform Infrared spectrometer (FTIR) is found in many scientific institutes, an FTIR with the synchrotron radiation instead of the thermal radiation light source have the benefit of high brilliance. The high brilliance property in turn leads us to the advantages in microscopy. We have three microscopes in the beamline.

AREA OF RESEARCH

• Infrared microspectroscopy

KEYWORDS

• High brilliance infrared synchrotron radiation, Minute samples, Mapping measurement with high spatial resolution, Low (high) temperature + high pressure

SOURCE AND OPTICS

EXPERIMENTAL STATIONS

High spatial resolution microscope (Bruker Hyperion2000)

  We introduced new Hyperion microscope in 2011. Improved optics and computers give us higher spatial resolution, improved quality of observation and fast mapping capability.

• Beam splitter: Ge/KBr, Mylar
• Detector: MCT, Si Bolometer
• Spatial resolution: smaller than 5 micrometer at mid infrared
• Optional instruments:
  • Cryostat (Oxford Microstat-He)
    • Temperatures: 4.2-400 K
    • Windows: Quartz, KRS-5, BaF₂, PP
  • Temperature controlled stage (Japan High Tech 10036L)
    • Temperature: -190-600°C
