Commissioning Results of the BTUC-PGM beamline

Abstract The CRG beamline was commissioned in June 2000. This paper presents the results of the first resolution and flux measurements. The monochromator resolution was evaluated using gas cell absorbtion measurements for argon, nitrogen and neon. The results of the nitrogen measurements demonstrate a resolving 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 100 eV for a 140 μm exit slit.
