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
Beamline 2 end-station and clean room.
