Spectrometer Calibration Beamline

Beamline 2 (BL-2) at SURF III is dedicated to spectrometer calibrations, and provides a standard source of irradiance from 4 nm to 400 nm. The beamline is partially sponsored by NASA and is heavily used by its associated programs. The beamline consists primarily of two calibration stations. The first station is a gimbals mounted on a milling table for vertical and horizontal translations transverse to the incident photon beam and pitch and yaw rotations of the user's instrument. The second station, located further away from the storage ring, is a 1.2 m × 1.2 m × 2.49 m vacuum chamber. The chamber itself can be translated 40 cm in the vertical and horizontal directions transverse to the incident photon beam. The user's instrument is mounted to a large gimbals in the chamber, providing pitch and yaw motions. There in no obstruction in the beamline between the radiation source and the user's device.

This beamline is heavily used by many users from government and academia. The beamline schedule for each year is normally set at a user's meeting held in the fall of the previous year. Scheduling for 1998 will occur after the completion of the SURF upgrade and commisioning process. For further scheduling information contact Mitchell Furst.
