The CRG beamline was commissioned in June 2000. This paper presents the res
ults of the first resolution and flux measurements. The monochromator resol
ution was evaluated using gas cell absorbtion measurements for argon, nitro
gen and neon. The results of the nitrogen measurements demonstrate a resolv
ing power of 10,000. The monochromator flux measurements were made using a
GaAs diode and show that the beamline can deliver 10(13) photons s(-1) at 1
00 eV for a 140 mum exit slit. (C) 2001 Elsevier Science B.V. All rights re
