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 vendors
integration sp Validation of the ABI vendors FEL lamps Determining
the SRF of ABI filters End-to-end calibrations of EXIS at
SURF-III/Beamline 2 Review of the SUVI vendor NIST SURF-III
