GENERAL BEAMLINE INFORMATION
Operational Yes

Source characteristics

5.0-cm period elliptical polarization undulator (EPU5)

Energy range

100-2000 eV

Monochromator

Variable-included-angle PGM

Calculated flux (1.9 GeV, 400 mA)

1 x 1013 photons/s/0.1%BW at 800 eV [Value reported is the merit function, flux = total flux x (degree of circular polarization)2.]

Resolving power (E/ΔE)

5,000-10,000 (at source-size limit; energy-dependent)
>25,000 (64 eV, 10-mm entrance/exit slits)

Special notes

Polarization is user selectable; linear polarization continuously variable from horizontal to vertical; left and right elliptical (or circular) polarization.
