Beamline 2: Spectrometer Calibrations


Absolute irradiance calibrations based on the calculability of synchrotron radiation are performed on beamline 2. See GOES-R/EXIS and SDO as examples.

Specifications / Capabilities:

  • Undispersed synchrotron radiation and instrument aperture are used as a standard of irradiance
  • First experimental station is located 11.6 m from the tangent point (2 gimbals mounted on a milling table)
  • Class 10,000 clean room access to large chamber, located 17.9 m from the tangent point (gimbals inside of the chamber allow instrument rotation; the whole chamber can be translated)
  • Calibrations provided from 2 nm to 400 nm with uncertainty from 1.0% to 0.2%
  • Clean, hydrocarbon free vacuum to avoid instrument contamination
  • Calibration of ultraviolet and extreme-ultraviolet detector packages for NASA and NOAA contractors
