| Source |

| Average Beam Lifetime |
20-40 hours, fill every 12 hours |
| Spot Size |
Automated slits allow the beam size to be match to the crystal size or reduced to minimize spatial overlap of diffraction spots.

| Optics |
a parabolic collimating mirror placed upstream of the monochromator, focusing mirror
|
| Flux |
10E(10), X-Ray photons per second through a 200 um aperture, 300 mA, 2.6 GeV,
lambda 1 Ang
|
| Flux Details |
flux measured in 1997 corresponds to NSLS x-ray ring emittance of 90 nm-rad;
NSLS x-ray ring emittance has improved to 45 nm-rad,
and this has resulted in about a factor of 2 increase
in the delivered fluxes;
A more up-to-date sampling of the flux
is not yet available.
