Pre-Launch Resources - NIST

5D-6

NIST is a resource leveraged by PSE/Program Science (CWG) in order to provide:

• Review of vendor calibration plans and test setups• Links to primary SI standards• Development of plans for SI-traceable calibrations

NIST is currently involved in the following activities:• Deployment of the Traveling SIRCUS to the ABI Vendor testing

facility• Blackbody characterization using TXR• Characterization of ABI vendor’s integration sp• Validation of the ABI vendor’s FEL lamps• Determining the SRF of ABI filters• End-to-end calibrations of EXIS at SURF-III/Beamline 2• Review of the SUVI vendor
